After all of the attention my post showing photos of lightbulbs burning out received last week, I thought I’d post another one. This capture shows the burning bulb a moment later than my earlier shots. The mushroom looking cloud (we’ll ignore other similarities) has floated up and is beginning to dissipate in this version. It is interesting to note that in nearly all of the photos the smoke plume is drifting to the right. I would guess that subtle airflow in the room is the reason.
To photograph this, I fired 8-10 shot bursts with my camera at 5 frames per second to increase my odds of capturing an interesting photo. I manually calculated the exposure after taking a few test shots. The only post processing I have done to this image is cropping, noise reduction and contrast adjustment (all in Photoshop CS2).
