Photographer Jeffrey Vanhoutte of Brussels, Belgium was recently tasked with shooting a series of photos for a coffee creamer company. They ended up doing a mixed photo/video shoot with a professional acrobatic dancer flinging puffs of white powder into the air while doing dance moves.
Last week we shared a guest post by photographer Martin Legeer on how he built a Matrix-style bullet-time camera rig using 50 Canon DSLRs. Shortly afterward, Greek photographer Theodoros Tziatzios of Real Creations sent an email telling us about his own camera rig projects, which use double the number of cameras.
That’s right: a camera rig with 100 cameras for extremely smooth 360-degree views of subjects that freeze time and space.
Last Friday an anonymous poster on the photography board of 4chan sparked a discussion that rippled into the blogosphere after freezing their camera to see whether ISO performance improves at lower temperatures.
They stuck their Sony A350 into the freezer for 15 minutes, and posted the following before and after comparison of noise at ISO 3200:
Regardless of whether or not these results were fabricated, it has long been (though perhaps not widely) known among photographers that digital cameras have better ISO performance (i.e. less noise) at lower temperatures, which is why sensors are often cooled for astro-photography. Other photographers also report improved ISO performance when shooting in very cold environments.
Zodiac Light did an interesting experiment in which a Canon 350D was cooled, and the amount of noise measured. They found that cooling the sensor resulted in a 40% drop in the amount of noise.
Obviously you shouldn’t freeze your nice camera to test this out yourself, but it’s an interesting fact to know, and could be useful if you’re interested in long exposure photography.
