    Re: Quick Question Tray Processing

    Nothing unusual about that. It's the water-soluble anti-halation dye from the back of the film.

    If you use a pre-wash, the dye ends up in it.
    If not, it ends up in the developer.

    The image circle of the 90 SWD is 236mm, while the diagonal of 5x7 is 218mm.
