Fujifilm's Instax SQ10 is already available if you want to take square-format instant photos, but what if its half-digital technology is still too close to Instagram for your tastes? Don't worry, you're covered. The company has unveiled the Instax Square SQ6, its first analog camera to take (you guessed it) square shots. The closest you get to digital is the programmable electronic shutter release -- otherwise, it''s mostly a throwback to the pre-digital days. Not that you go without some creature comforts.
