I've been using XP films since they were introduced and I found an undeveloped roll of XP1 in my studio that was exposed in 1990! When I had it processed yesterday the latent images had faded, but I got some prints. One group of images had reversed, that is printed as a negative image. Does anyone have any experience with what happens to chromgenic films as they age and if the revesal is "normal" chemical changes in the film.
