yes they all are, it's part of what the medium is, it's like being a little pregnant.
sure OK, the latent image is fake too, I can live with that, but sadly, I don't think you can
the latent image is the result of invisible rays of light that brushed upon the light sensitive materials, and have "indexed" the thing in front of the camera. they haven't been preserved in any means so im not sure how they are manipulated
as seen here and on other photographic forums people develop latent images years, sometimes decades after they impregnated the film (or plate ) .. but I guess it's a physical reaction so sure, it's fake ..
as Edgar Allen poe said soon after the invention of photography: believe half of what you hear and none of what you see ...
