Creating a photo with a pure white background


Love it or hate it, a popular style of shooting in stock photography is the photographing of models or objects against a pure white background. By pure white I mean a background with absolutely NO detail, RBG values of 255,255,255 - Nothing!

There are an abundance of ways to create this look from simply cutting out the subject in Photoshop to doing it entirely 'in camera'. I prefer to go for the latter method.

For today's featured image of Michelle holding a weight, I relied on a studio setup to create the majority of the 'pure white background' in camera and then finished off the look in post-processing. To setup the shot, I placed two monolights shooting through white umbrellas onto the background of white seamless paper.

Picture 8

I set the monolights so that the exposure on the background was in the range between f/11 and f/16. For me, using lights of different power it took a small bit of adjustment to get it right.

The next step was to place Michelle in front of the white background at a distance that would give a nice rimlight from the background reflection but not overpower her. Since this photo was for a stock purpose I allowed the light to reflect a bit aggressively onto the left side of her face. Had this been for a portrait, I would have adjusted differently to eliminate this.

I lit Michelle with a combination of a large softbox and a reflector. The exposure metering for her was f/8. This is what I set my camera on. By doing so, I had a background that was sufficiently over-exposed but not so much that it caused excessive blow-back which can lead to problems like lens flare, blown edges and such.

In post-processing, I shoot RAW so the first step is to convert the RAW file in AdobeCameraRaw (ACR). My default setting in ACR is to show pure white highlights as red and pure black lowlights as blue. As can be seen in the screenshot, my shot came close to having a pure white background with very little adjustment.

Picture 4

Now, with the majority of the work done, I open the image to complete editing in Photoshop. I know from what I saw in ACR that I will have a few areas to clean up to guarantee a pure white background.

After opening the image in Photoshop, the first thing I do is create a temporary Brightness/Contrast adjustment layer and pull the brightness slider all the way to the left. What this does is show me the areas that I have to finish cleaning up to get the desired white background. Any area that is not absolute white (255,255,255) will be immediately apparent.

Picture 6

To clean up these areas, I will use one of a couple methods. If it is an easy spot in a corner or two, I will simply create a new layer and paint the area(s) white. If it requires a bit more finesse because it's around the model (like this image), I will use a levels adjustment layer along with some vector masking. Once I get the background how I want it, I then delete the temporary Brightness/Contrast adjustment layer that I created.

After creating my white background, I then go on to complete my processing including other steps like facial retouching, whitening eyes and teeth, sharpening, etc.

As you can see by this example, the easiest way to create the background and my preferred method is to do as much as possible in camera. In doing so, the Photoshop work required for a series of images is minimized and this dramatically drops the time needed sitting in front of the Mac.

Calling Photoshoppers II - The Results


Last week I put out a second call for readers who would like to put their photo editing skills to work on one of my images (original post). Within an hour I received email from four volunteers wanting to take on the task.

I have since received the four edited images. In addition to doing a great job applying their editing chops to the image, they each wrote a narrative on what they did and why they did it. While the results are similar in many ways (no one cropped the shot?), they each added a little variation.

Each person was provided with an unedited JPG and RAW image (shown above) of the model standing on the rock at the Great Salt Lake. The only guideline given was that they could do whatever they wanted. Here are their results in no particular order.

Jake Spurlock

Calling Photoshoppers 1

I was really excited when I saw that this was going to be the photo to work from, especially after I was unable attend the Photowalk at the Great Salt Lake a few weeks ago, and was further depressed when I saw the breathtaking images that came back to Flickr as a result. So, how cool is it then to get the chance to edit this image, and get to put a little bit of Jake Spurlock into it.

To Start:
I do all of my processing by starting with Apple Aperture. Beginning with the RAW 2.0 processing, I delved into the levels adjustments. I pulled black to black, crushing the blacks a little, created some highlights in white, and the made a nice midpoint. I did this on all three of the color channels respectively.

After levels, I moved into contrast, definitions, saturation, and vibrancy. When I take pictures, and then edit, reality isn't at the top of my list of rules to follow. If I was going to make movies, 300, Batman Begins, and Speed Racer would be the inspiration. That being said, this photo evokes the idea of a warrior princess, standing guard over a kingdom. So, contrast is pushed, super saturation, and the image gains a lot of character.

One cool Aperture feature is the shadow recovery tool. Basically, it selectively adds some gain to the black areas of the photo. For video people, similar to setting the knee level for broadcasting equipment. Boosting this brought a lot of detail in from the rocks, and really shows off their awesome texture.

With these adjustments, I was really satisfied with the clouds, rocks and water. Yet, the warrior princess was a little dim, and lacking the glow that she deserved. So, I created a new version from the master, and went to work again creating the same look for her. When I was content with how she looked, I exported versions of both images, and brought them into photoshop for some blending.

This was a pretty simple, yet laborious process. I am sure that everyone reading this has had to do this before, so I won't go into to much detail. I had my darker layer as the background, and then pasted the other on top. I went to work with the eraser/lasso/marquee tool getting rid of the excess. If you look at my image and contrast to the original, she is clearly a blond in the original, but I really like the look of her with dark hair and used the darker background source for that.

When all of the erasing was done, I used the dodge tool around her outline on the background layer to give her a little bit of an angelic glow. Followed up with spot healing brush for some legs, arm and face. I don't bother too much, after all this is a warrior, not a cover model. ;) After that, save as a .PSD, and reimport back into Aperture.

Once back in Aperture, I added another round of vignette. It created those dark and foreboding clouds, and added to the rock detail at the bottom. Part of the post process is to send revisions back and forth to my wife who has a great eye for detail. Wrote up a summary, and off to Rich for posting!

Thanks, what a fun process!

How I Did It:

1. Adjust the RAW image using Adobe RAW for white balance and contrast. Most of this was done in the basic panel of sliders. Some additional HSL panel adjustments for color, especially the skies. Opened in Adobe Photoshop CS3.

2. Placed a second copy of the same image as a layer with RAW exposure adjustments for the model (ignoring the background). Masked this layer to block everything but the model. Rasterized this layer.

3. Made a copy of the second layer and changed to "Screen" mode for even more lightening of the model. Adjusted opacity of this layer to 27%.

4. Added a layer for cloning and healing tools. Used the "sample all layers" option to adjust the models dress to hide the seam in the middle. Felt like the leg showing and uneven shadows of the dress were distracting. I also removed some of the brighter splotches of white on the rock for the same reason.

5. Added a "Dodge & Burn" layer, which is a new layer filled with 50% gray. Using a larger brush set at 8% brushed in white and black alternately in varying places for contrast and emphasis. This was mainly used to darken the rock base and even out the exposure on the rest of it. I also increased the cloud dramatic contrast.

6. Added another masked dodge & burn to give a glow around the model for a kind of other-worldly glow, like the heavenly lights are pouring down on her. Cheesy I know, but it seemed to fit.

7. Added a photo filer layer to warm up the image a bit overall. Default warm (85%) color with a little added density.

8. For the web resized image, I downsized, added some Smart Sharpen filter on a copied layer (72%, 0.3 radius). Masked the layer and brushed on where I wanted the selective sharpening applied.

Thank you for the chance to work on this challenge. As a beginner, I appreciate the opportunity to concentrate on the post-processing only, while knowing that the result will be critiqued by a gifted and experienced photographer.

The picture has a very interesting composition and a lot of detail. This abundance of detail, especially in the rock, made me decide to go B&W. I also liked how the model's dress stands out in the original, so I ended up going with selective desaturation.

To obtain the B&W, I output the red channel to gray using a channel mixer layer. I also added a Curves layer to darken the shadows a bit. Still wanting more contrast in the rock, I isolated it, copied it onto a new layer, and applied an overlay blend mode.

The red dress was isolated using a color range select, and then tweaking that selection with mostly the eraser. I then brightened the red a little by turning the cyan down in the red channel of a selective color adjustment layer.

I hope to have done justice to your great photo.

The original image itself had a very nice contrast to it so I decided not to tamper with it too much. To me, this was one of those images that needed very little modifications to make it look the way it should. So below are some changes that I thought would make the image look better.

1. I started off by adjusting the color curves in GIMP to enhance the overall temperature of the image.

2. I then adjusted the color levels to enhance the contrast of the models bright red outfit to the cloudy background.

3. I sharpened it to make the image crisp.

Thanks for giving me this opportunity and would like to participate in another one if possible.

Calling Photoshoppers, Take 2


Last January we had a bit of Photoshop fun here on the blog with the Calling Photoshoppers post. In it I invited a few photographers to give a shot at editing one of my images. I then posted the results for everyone to see. It was pretty cool to see the different take each photographer took in editing the image.

Well, it's time to do it again.

I am looking for four blog readers that would like to put their photo editing chops (Photoshop, Gimp, Lightroom, Aperture, etc.) to work on an image that I supply. They will each have one week to do whatever they would like to the image. In the end, I will post all the edited images along with the photographer's commentary on what they did and why.

If you are interested in participating, please email me at rich(at)leggnet.com with the subject of "COUNT ME IN!". I will take the first four respondents (plus one alternate).

UPDATE: We've got our participants. Thanks for the speedy replies.

Mirrored Imagination


Today's image is a concept shot I did after last week's White Bedroom shoot. I like the idea, but I think I'm going to photograph it again in a more natural setting (bedroom, store, etc.).

Muted Color


One effect that I use occasionally on portraits is Muted Color. This treatment can help to give an antique feel to the image similar to sepia-tone while still retaining color.

The young couple in today's image wanted an old-fashioned look to their engagement photos. Their initial thought was to go with black & white or sepia-tone. However, upon seeing the muted color version it immediately became their favorite.

There are several methods available to create this look. The method I use is simple and straightforward. I process the original RAW image in three ways: color, sepia-tone and cross-processed (I use Linge's Photoshop Actions for the sepia and cross-processed effect). I then create a Photoshop layer of each version of the file. Once I have the three layers, I use the color layer as my base and blend the other two layers over it, adjusting the transparency until I get my desired result.

If you have a process you use to create a similar effect, please share it.

Photoshop Tip: An Alternative to Brightness/Contrast


When editing my images in Photoshop, I always begin with a couple simple adjustment steps before venturing into the more advanced edits. Since I shoot most of my shots around 1/3 f/stop underexposed (to preserve highlights), the first simple editing step I do is an adjustment to the brightness/contrast of the image. But guess what? I don't use the brightness/contrast adjustment to do this. I use LEVELS.

By using the LEVELS adjustment, I am able to fine tune the brightness of the image while causing very little damage. This is extremely important in my stock images since they have to go through a rigorous inspection process to be included in my portfolio. Here are the simple steps I use:

1. Create a new LEVELS adjust layer.

2. Slide the upper clipping adjustment (red circle below) down until it is just above the upper end of the histogram.

3. Slide the lower clipping adjustment (blue circle below) up until it is just below the lower end of the histogram.

4. Inspect image and fine tune the adjustments as needed


Levels 2

As you can see in today's featured image, the sample on the right 'pops' quite a bit more than the original on the left. This was done strictly using the levels adjustment. Once I complete this step, I then go on and finish my editing of the image.

If you haven't tried adjusting brightness/contrast this way, give it a shot and see how well it works for you.

Calling Photoshoppers - My Version


It was great to see the response to the Calling Photoshoppers project we featured this week (original post). I received a few suggestions that I give a shot at editing the image, so I spent a few minutes with it this morning. Here is my version.

I didn't keep a detailed list of my editing steps (like the others did so well), but I will touch on a few highlights.

- Cropped and leveled
- Removed rock (thanks Brian)
- Blended two versions of the images, one sepia and one color
- Warmed up and softened using an action
- Brightened faces
- Vignette

My goal was to create a sepia image with a subtle color on the couple (especially the jeans and her top). Similar to others, I sought to create an old-fashioned feel to the image.

So, how'd I do?

Calling Photoshoppers - The Results


Last week I put out a call for Photoshop users who would like to put their skills to work on one of my images (original post). I received a very nice response and selected the first five to participate.

I have since received the four edited images (one person was unable to complete the assignment). In addition to doing a great job applying their Photoshop chops to the image, they each wrote a narrative on what they did and why they did it. It is very interesting for me to see the different style and approach each artist took.

Each person was provided with an unedited JPG and RAW image (shown above) of the couple walking on abandoned railroad tracks. The only guideline given was that they could do whatever they wanted. Here are their results in no particular order.

ANN TORRENCE

Technically

In short - two Adobe Camera Raw interpretations of the same image,
over and under exposed. The diffusion is simulated by copying the
over-exposed image, blurring it, and using the Screen mode.
Calling Photoshoppers - Results
The under-exposed ACR conversion is blended with Multipy at a partial
opacity to bring back the dark zones. A Curves Adjustment Layer
introduces the Cross Processing look; search on-line for many cross
processing curve examples to download. One more thought: edit in 16-
bit mode when making dramatic shifts and expect a spiky histogram.
Down-sampling to 8-bit will smooth much of the spikiness out.
Cropped to 8x10, light sharpening for Rich to resize and sharpen for
printing.

Artistically

I imagined this couple would like one image from their engagement
session styled for fashion. I wanted to give them an image that they
will like now, their kids will laugh at on their 25th wedding
anniversary, and treasure on their 50th.

I liked the pose, motion and expressions, and how the color of her
shirt pops out of the image. But their beautiful skin and hair tones
get lost in the muddy colors of the tree leaves. And the unfocused
weeds at the bottom of the image have to go (Rich was smart to keep
the camera plane parallel to the couple, and allow some room in the
composition for cropping.)

Cross-processing refers to an old-school color film technque of
processing slide film as if it were color negative or vice versa. It
gives a characteristic color shift and contrast transformation to the
film, and has been used a lot in fashion photography. Another tool
fashion photographers might use is a diffusion filter. Since Rich
didn't use one on his lens, I faked one. I wanted to use both ideas;
retaining a full range of brightness called upon a bit of Photoshop.


BRIAN AUER

Calling Photoshoppers - Results

Technically

I processed the RAW file using Adobe Camera Raw 4.3.1. I left the white balance as shot, and I started with the “Auto” adjustment for the exposure settings. I tweaked a few minor things, then I got started in Photoshop CS3. Once in Photoshop, I applied a curves adjustment layer to increase contrast. Then I converted to black and white using the Channel Mixer adjustment layer at 34% red, 66% green, and 0% blue. I set the blending mode of this adjustment layer to “Overlay” and dropped the opacity to 80%. Then I desaturated the image using a Hue/Saturation adjustment layer by dropping the Saturation slider to -35. The final adjustment step was a Photo Filter adjustment layer using an LBA Warming Filter at a density of 35%. Then I cropped the image (see why in the next section). And finally, the rock in the foreground was a little off for me, so I cloned it out. No sharpening was applied.

Artistically

I felt the scene had a lot of potential and I knew I wanted the image to have a kind of timeless and carefree look and feel to it. The adjustment layers got the overall mood where I wanted it, but the composition was off for me. I loved the slight tilt in the image, but the upper half of the scene wasn’t working for me – the background was too dark on the left and too light on the right. It added too much tension and took away from the “carefree” feeling I wanted. So I played around with different crops and I finally landed on a 3:2 aspect that cut off just below the cuff of the white shirt on the left arm. To me, this was the most interesting part of the image (no offense to the models… or Rich for that matter). The photo was suddenly more timeless and relatable. It wasn’t about the two specific people in the photo -- it was about the carefree feeling of walking down the old tracks on a sunny summer afternoon, hand-in-hand with the person you love.


RICHARD MILES

Technically

My first step was to eliminate some of the empty space around the couple, so I cropped the image to bring the couple forward. I then tilted the image to take away the linear power that the original had, and also in hopes adding a more visual element to the picture. Overall, I felt the image had too much space around it, and was too much on the straight and upright!

Artistically

I bumped the contrast a little! I also played with different levels of contrast and decided that since the couple are wearing jeans containing pattern and texture , to bring out that element and use that as a unifier that this is a "couple"!

I then added a soften glow to the shot, and then layered a sepia toned layer on top. I took a black paint brush at around 2% opacity and painted over the whole image to achieve that black/sepia combo and add a little warmth and hopes of a romantic flair.


TIM MILLER

Calling Photoshoppers - Results

Calling Photoshoppers - Results

ARTISTICALLY

I looked at the photo and it seemed to be a pretty candid shot snapped mid action, but when I thought about it from the perspective of the couple, there was obviously going to be some memories associated with the event. It was obviously a staged candid shot. The railway tracks and the way they were dressed and walking holding hands suggested that a photographer had set this shot up for them – maybe as a anniversary special photo occasion or something. So while wild fantasies of photo shopping an old fashioned steam train in behind them to make them look as if they were in danger crossed my mind (in fact I even found some suitable photos) I didn’t attempt this. Instead I reasoned that the couple would be interested in framing this photo on their wall as a memory of this event or time in their lives. So I created two different looks and borders that would lend themselves to printing on canvas or photo paper and framing with a nice frame.

TECHNICALLY

Shot 1 – the sepia image. First I tightened the shot by cropping substantially. I then copied this onto a larger white canvas to create a large margin. I then changed the image to black and white using a gradient adjustment layer and then added a colour adjustment layer of sepia. I then created a slightly larger selection in the background and filled this with black to give the old time real photo look of the black edges and sepia tone. I then added the text at the bottom. This would look good in an old wooden frame – probably 2-3 inches in width in an old fashioned style.

Shot 2 – the soft edges. Once again I tightened the shot by cropping the extraneous material. I then create a border inside the edge and feathered this by 170 pixels. I then selected the inverse and deleted to create the soft edges. This would look good on a matt photo paper and framed in a thin metal frame, gold or maybe silver.

____________

And there you have it. I would again like to personally thank each participant for taking the time and energy to be involved in this little project. Based on the response, we will be doing this again in the future.

Calling Photoshoppers


My college age son spent some time with us over Christmas break and offered up a suggestion for a blog post here on LeggNet's Digital Capture. He thought that it would be interesting to see different photographers' final version of the same photograph after editing. I agreed that it would be cool, so we are going to do it.

I am looking for five blog readers that would like to put their Photoshop chops to work on an image that I supply. They will each have one week to do whatever they would like to the image. In the end, I will post all five images along with the photographer's commentary on what they did and why.

If you are interested in participating, please email me at rich(at)leggnet.com with the subject of "COUNT ME IN!". I will take the first five respondents.

This will be fun!


UPDATE


We've got our participants who will each be receiving the un-edited image in the next day. I can't wait to see the results.

UPDATE 2

The image file has been delivered to each of the participants. I anticipate posting the results along with their comments by the middle of next week.

Photoshop Tip: An Alternative to Unsharp Mask


Earlier this week, I mentioned my recipe for having a high percentage of my photographs accepted into my portfolio on istockphoto.com. One of the key ingredients to my system is NOT using the popular UNSHARP MASK filter in Photoshop for sharpening. While this filter does a nice job for sharpening images to be printed, I find that it can be detrimental to the quality of stock photos which get inspected with a fine-tooth-comb before begin accepted.

The alternative method I use for sharpening is the HIGH PASS FILTER method. This method provides good sharpening while minimizing image degradation. Here are the steps:


1. Create a COPY of the layer you wish to sharpen

2. Select FILTER, OTHER, HIGH PASS

3. Set the radius to 4 PIXELS (then click okay)

4. Change the blending options of the new layer (by double-clicking on the layer) to SOFT LIGHT for mild sharpening or OVERLAY for stronger sharpening


It's a very simple method for clean sharpening of photos. To make it even easier, I have recorded the steps as an action that I can run with the press of one function key.

If you haven't tried sharpening this way, give it a shot and see how well it works for you.


Additional Note (Added on 15 November)

In response to a comment about this method causing an undesired "HALO" effect, let me add a clarification (that I should have included originally). This method is intended to be used on FULL RESOLUTION images of 8+ megapixels. Using it without tweaking the 'RADIUS' on smaller images will give an undesired result.

Down on Mainstreet


I made this capture while crossing Salt Lake City's Main Street on a rainy Saturday night . The saturated color and high contrast were added using a Cross Processing effect in Photoshop. My favorite parts of this image are the the reflection created by the wet asphalt and the lines leading from the lower corners. The fact that the technical quality (noise, blur, etc.) of the image is rather low but the visual appeal is high is simply a bonus.

Cross Processing with Photoshop


The term Cross Processing is a hold-over from the film era. Before digital, it referred to the act of using the wrong chemicals to develop film. For example, a photographer would develop transparency film (E-6) with developer intended for color negative film (C-41). The distortion this caused in the image's color and contrast could lead to some rather stunning images.

In today's digital world, we can reproduce this technique in our editing software. In the past when I wanted this effect, I followed some step-by-step instructions I found on the web. In an effort to simplify my post processing workflow, I am now using a Photoshop Action Set to create the effect. I purchased the set at a seminar I attended taught by Kenneth Linge. Now I can consistently create this affect to my images with one click.

Today's image of Erik has the cross processed effect applied. The stark contrast and colors add to the moody feeling in the capture. For comparison, here is a link to a black & white version from the same shoot.

Alaskan Window Boxes


I'm in Anchorage for a few days before heading north on the Alaska Railroad. I spent some time wandering around the downtown area yesterday afternoon where I captured these window boxes. The window was located on the second floor and the image had a distinct 'looking up' feel to it. To compensate for this, I adjusted the vertical perspective in Photoshop to make it appear to have been shot more straight on.

Play Ball


For this capture of an empty baseball diamond, I used some fairly aggressive settings in Photoshop CS2's CHANNEL MIXER tool to convert the shot to black & white. I pushed the BLUE slider to the 200% level and then used a negative 100% setting on the GREEN slider to even out the levels. This technique resulted in the very dark dirt and the washed out sky.

Soon though, I won't be using the CHANNEL MIXER adjustment layer for my black & white conversions. My upgrade to Photoshop CS3 should arrive this week and I will begin using the new BLACK & WHITE adjustment layer feature. This is just one of the (many) reasons I opted for the upgrade.

Want Greater Photographic Flexibility? - Shoot RAW


One of the choices that face digital photographers is the format in which to save their images. Most advanced digital cameras offer several choices of format to choose from. A typical selection would be something like this:

- Small .JPG
- Medium .JPG
- Large .JPG
- RAW

Today I am going to talk a bit about the last selection on the list - RAW. A RAW image is essentially the unprocessed capture taken directly from the camera's sensor. When the camera captures an image in the JPG format, the on-camera software processes the file before saving it. This processing includes such things as contrast, color saturation, sharpening, etc. The RAW image has had very little, if any, processing applied. Hence, the name RAW. It is essentially a digital negative, ready to be developed.

"Why would you not want the camera to improve the pictures you've taken?" I've been asked. The simple answer is that many photographers (myself included) prefer not to have the camera make the image enhancements. Instead, they opt to do it themselves on the computer. Also, the RAW format allows for much greater latitude in adjustment that can be applied.

For an example of this adjustment latitude, I walked into the field behind my home and purposely made a capture that was +2 f/stops overexposed. I set my camera to record both a JPG and a RAW image simultaneously. This would allow me the opportunity to edit two identical exposures, one RAW and one JPG, and compare the results.

Here is the unedited (other than a small crop) JPG, straight from the camera:

2 Stops Overexposed

As you can see, the image is pretty much blown out with a very bland look to it. The highlights are completely washed out. If you were to look at the histogram (more on this in another post) of the photo, it would look like a ski ramp.

For my first go at salvaging this overexposed image, I used the JPG version. I used Photoshop's BRIGHTNESS/CONTRAST tool along with the magical SHADOW/HIGHLIGHT tool to attempt to bring the levels into shape. I also worked on the color with a SATURATION layer and did a bit of sharpening. Here is the result I achieved with the JPG:

2 Stops Overexposed JPG edited

The result is not too bad. It could be used in a pinch, though it is not an image I would be pleased with.

I then took the RAW version of the capture and began editing it. The first thing I did was to open it with Photoshop's Adobe Camera RAW tool. This nifty interface allowed me to fine-tune the image's color and exposure before opening it in Photoshop proper. Once in Photoshop, I adjusted the Curves, Saturation & Levels using adjustment layers. After a brief period of editing this is the result I achieved:

2 Stops Overexposed RAW edited

I feel that this image looks much better than the edited JPG version. Other than the section on the top/left of the wooden post, there is very little "blown out" area within the shot. This edited photo is much more pleasing. Also, it took much less effort in editing to achieve this.

Finally, still not being satisfied with the capture, I went a bit further. To complete the editing, I converted the image to black & white and added a sepia tint to it along with a bit of vignetting. The final result is the capture at the top of the page.

For me, making the switch to RAW was a no-brainer. Once I got over the initial learning curve of the extra steps required in editing, I fell in love with the greater control I received in editing. Today, if I shoot in JPG I simply don't feel comfortable. I would much rather have the control and latitude offered by Shooting RAW.

Through the Viewfinder Photography


A commenter on one of my photos on Flickr suggested that I should apply a TTV Layer to this capture of an old mill I took in Salt Lake City. I read the comment and then had to admit that I didn't know what TTV photography was. A quick trip to Google and I discovered that TTV stands for "Through the Viewfinder". Here is a definition found on a Flickr group dedicated to the art:

"Through the Viewfinder photography is defined as taking a picture of any subject through the viewfinder of any camera with another camera."

The technique intrigued me. But since I didn't have the option of re-taking the photo of the mill through an old camera's viewfinder, I sought to re-create the effect in Photoshop. After a bit more searching via Flickr, I found another group - this one dedicated to images that can be used as layers to create this technique.

Once I had the viewfinder image, the rest was fairly simple. I used Photoshop's MOVE tool to drag the viewfinder image onto my original photo. I then adjusted the new viewfinder layer's blending mode to MULTIPLY. This allowed the layer with the mill photo to appear as though it is being seen through the viewfinder layer.

I am not too sure of the usefulness of this type of image, but I do think it adds a nostalgic quality to the photograph.

I'm Still Photoshopping My Photos


Adobe, the creator of the highly popular image editing software Photoshop (the program I use for editing my captures), has recently stated that the name Photoshop is not to be used as a verb. In fact, they have a whole section on their website detailing the company's policy on this.

Here is a snippet from Adobe.com:

The Photoshop trademark must never be used as a common verb or as a noun. The Photoshop trademark should always be capitalized and should never be used in possessive form, or as a slang term. It should be used as an adjective to describe the product, and should never be used in abbreviated form. The following examples illustrate these rules:

Trademarks are not verbs.

CORRECT: The image was enhanced using Adobe® Photoshop® software.

INCORRECT: The image was photoshopped.


I think it is a bit late to enforce this policy on a large scale. The word photoshop has become synonymous in the photography community and increasingly in mainstream speech with the word edit. Just this past weekend I overheard the following exchange:

person #1: "Check out this picture of a giant dog."
person #2: "I already saw that. The dog's not really that big, it's photoshopped."

To further illustrate my belief that it is too late for Adobe to prevail in this area, one only has to go as far as Dictionary.com. A quick search on the popular site for the definition of "photoshop" yielded this result:

"...to edit an image using a computer program," 1992..."

What I suspect is really going on here is that Adobe is required to have a policy in effect to protect their trademark. Without this effort, they run the risk of losing the claim to ownership of the name Photoshop. Google had a similar problem last year since their name was increasingly being used as a generic term for search (i.e. "just google for the answer").

I can understand why companies like Adobe and Google don't want their trademarked names to go the way of Xerox & Kleenex and become generic terms. But in the photography community I think it is too late.

As for me, I will continue photoshopping my photos. What about you?

An Experiment in Post-Processing


This image is the result of some recent post-processing experimentation. I had seen a similar style applied to portraits and sought to create the effect myself. I wanted the eyes to remain fairly sharp while having much of the remaining image appear almost animated with a blurred glow. My workflow on the shot was mostly trial and error. The resulting photo came very close to what I desired.

Now, if I could only remember the steps I took to create it... :)

Creating a Cross-Processed look in Photoshop


Sometimes an "Oops!" can give you an unexpected good result. This is the case with Cross Processing.

"What is this Cross Processing you speak of?" you ask. Simply put, it is the processing of film in chemicals that are not intended for the type of film being processed. An example is developing slide film (E-6) in chemicals intended for negative film (C-41), or vice versa. I can imagine the first photographer's reaction upon discovering that he (or she) mistakenly created this process when looking at their developed film. The resulting effect that this gives an image can vary quite a bit but one common result is blown-out highlights and colors that just "aren't right".

In seeking to create a cross-processed effect in Photoshop, it took a short trip to Google. The search resulted in a couple of tutorials on the subject. The easiest instruction set I found was located at PhotshopSupport.com. The tutorial there was easy to follow and included screen shots of the Photoshop steps. I created the image of Michelle in this post using their formula. Notice the yellow-green tint to the skin tone and the bright color of the lips. The effect can be a bit surreal.

Here is another example of the process on a similar shot. On this photo, I added a film border as recommended in the tutorial to add to the effect.

And finally, here is one more example applied to an image of an old mailbox.

If you have given Cross-Processing a try (either with film or digital), please share you results - I'd love to see them.

My Post Processing Technique


I have received a couple of questions about my technique in processing images. To assist in showing how I do it, I thought I'd detail the steps I took in processing a photo such as the one posted yesterday. This photo was taken on the spur-of-the-moment when Michelle walked by. I was playing with a soft-box and asked her to stop and pose for the shot. I am self taught in all of my post-processing so I am sure that the 'pros' have better techniques, but this is what works for me.

ORIGINAL IMAGE

Here is the original image after doing the RAW conversion from the camera file:

STEP ONE

I use the CLONE tool to remove her necklace, earring holes, skin blemishes and background distractions.

Step 1


STEP TWO

I apply noise reduction, slight sharpening (via Unsharp Mask) and crop the image.
