I don't quite get this. We are taking a picture of a fully backlit transparent object. My understanding is that all the film layers act as a filter for the light. So all layers will be equally involved regardless which one is in the front.
Anyway I did some research: https://www.google.com/search?q=dslr+film+scanning+emulsion+up+or+down What I understood from people's comments is that for flatbed and filmscanners it does indeed make a difference, i.e. avoiding newton rings, and possibly other benefits, but it seems so to me that with dslr film scanning most people agree that they see no noticeable benefit of having the emulsion side down. thanks: m On Thu, Aug 13, 2020 at 10:36 AM <[email protected]> wrote: > Hi, > > you want to take an image of the emulsion layer (which contains the > photographic information).
