Hello all, I am working at a small design agency, and we're working on a design concept for which I'd like to get some professional advice. We have been commissioned to come up with an invitation card concept for which the theme is time, and we came up with the idea of using large format polaroids--the ones which require the peeling of a protective film to trigger image formation--that contain the necessary party details. The idea is that we'll have a photographer shoot an image with the polaroid, leave the protective film untouched, and send it to the guests, who will have instructions to peel away the film and see the image appear slowly before their eyes. Unfortunately--and this might be evident already from my language--we are quite unfamiliar with the characteristics of these polaroids, and are not sure at all whether this might work. Will the polaroid still retain its image even if say--the protective film is peeled quite a few days after the image is shot? If so, how might its image be affected or altered?
