Hi everyone!
Okay, so firstly, I DID SEARCH THE FORUM ON THIS, and Googled and whatever, but I thought a post here might help me with a question I can't seem to get a definitive answer on. I am hopeful some of you have experience with this (which you probably do).
I am currently cutting a Red feature (4K 2:1) and we will probably be finishing either 2K or 1080, both for 2.39. I have learned that we will be doing an end-credit sequence using some old photographs (no negatives -- old Polariods, Fotomat prints, that sort of thing). I was planning on building it in After Effects or FCP myself, and providing the DI lab with a completed piece of media. I don't believe that the photos will be "zoomed in" or moved around (a la Ken Burns), but of course we may do that, I don't know for sure.
In any case, I am trying to figure out if there is a standard spec for scanning photographs. Photo people don't speak in pixels, they speak in dots and inches. I understand that video is always 72dpi. For HD, or 2K, would it / should it be more? Would 150dpi or 200dpi, for example, be a bad thing? When the photo labs ask me how many inches I want, I have no idea what to tell them.
Ultimately, I want this feature to be able to have a film-out with no problems, and otherwise look great in all formats. I don't want to scan and then re-scan again, I sort of want to do it once and do it right (if that's possible considering the things I don't know).
Does anyone have any advice on this?
Thank you, and happy new year!
Karl
