    Dear Bohngy;
    When processing film in smooth walled tubes I use fiberglass window screen between the film back and tube wall. Just cut some 4x5 pieces to fit and load the tube making certain that the screen is against the back of the film. The screen allows the chemicals to reach the entire film back and problem solved. Be sure to rinse and dry the screen before use.

    [QUOTE=Photo Engineer;831980]The color coming out during the prewash is mainly due to acutance dyes and trimmer dyes. The latter adjust the speeds of the 3 layers or trim them, to assure an exact speed to the film and an exact speed relationship between layers. The acutance dyes enhance sharpness by reducing the effects of turbidity in the coating.

    Nothing in this discussion is related to anything I do in the darkroom and probably never will. I just want to chime in to say I sure am glad you stick to this user's group to provide answers like the above. Thanks.
