I used to do continuity on film shoots and we always used Polaroids to make sure everyone's costumes, hair-lengths, make-up (especially bruises and fake tattoos), cigarettes, drinks, etc. were all properly in place from day to day. Everything you see in film and television is shot out of sync, unless it's one long take. So now do people use digital cameras for this? You'd have to have a pretty big view-finder to tell how long someone's cigarette butt should be for the next day's shoot/smoke. I guess you could plug everything into a printer and print out the day's photos; one more step to deal with in your long work-day. I will miss watching the development of instant, square-framed, oddly saturated Polaroids.
