Interesting; thanks for sharing. Your observations show that I was wrong, thinking that variations of intensity would not be noticeable.

I recently took a slow motion video of a drop forming and falling from a spigot at 410 frames per second. I illuminated the area with a 100 W incandescent light bulb and on playback I noticed the variation in brightness of the white wall in the background, no doubt due to the small but noticeable cooling and warming of the bulb's filament.
