The light flicker is caused by slight variations in the camera's automatic settings for each shot. With most DSLRs, you have to pick what dimension you want to control (shutter speed, aperture, exposure, etc.) and then the camera figures out the other parameters based on what you've chosen and the conditions. By using RAW files, I was able to make sure that all the photos used as many of the same settings as possible. To film this, I brought the cactus inside so it wouldn't move with the wind, closed all the blinds, left the room's light on all night, and used the camera's built-in flash. I'm really not sure how to keep the lighting any more stable than that beyond getting a good light source and eschewing the flash. Hopefully I'll have a new desk lamp (mine's <a href="http://erikras.com/2007/12/16/bright-lamp/" rel="nofollow">broken</a>) for the sequel in 2009. That’s good point, Hubbers.
