    He did mention developer recipe, suggesting a "homebrew" type.

    Sure sounds like two distinct problems, negatives opaquely dark on one side and light on the other is fogging, no rebate visible and thin gray on the light side is a sign of almost "dead" developer and not as much fogging.

    Thanks for the replies everyone. You're right about the homebrewing. I've been trying things out with Caffenol-C. I know this is very experimental and what not, but wanted to know if it was light leaks or too weak/strong of a developer. That way I could fix my brew or my bag accordingly.

    It sounds like it could be the brew so I'll either make it stronger or change my dev or agitation.

    My advice would be to try a developer that you can purchase. A bag of D76 will only be a few dollars, and could help you solve your problem quickly. It could be gross underexposure, gross underdevelopment, or a combination of both.

    Keep the D76 around until you have gotten the activity of your Caffenol up to snuff.

    Doesn't Caffenol require a 30 minute or so developing time?

    I guess i'll try that then. At least that way I'll know if it's my developer for sure. Trial and error and a little bit of know how.

    That's caffenol. I was using caffenol-c. It adds vitamin c to the mix which speeds up the dev process. One problem I could have is tht my vit c might not be pure enough which would make me need a longer time than I used.

    Supposedly it has to be pure ascorbic acid, the vitamin C sold in most stores has a bunch of additives, which may impact negatively the results.

    One or more empty, cleaned out and clearly re-labelled plastic beverage (soda pop or tomato juice) bottles make great containers for darkroom chemistry.

    I use these (inherently Canadian as they are):

    All what the Kodak document says is

    Store stock solutions in tightly closed bottles. Solutions in
    full bottles have a longer shelf life; partially filled bottles
    allow some oxidation of the solution.


    So my best guess is that you don't, but you might wanna get glass marbles or those collapsible bottles.
