    D76 and Asprin

    On another site some posted that he increased "sharpness" with D 76 by adding an asprin tablet to a gallon of stock D 76. News to me, but I do not use a lot of D 76. Any idea if there is any science behind it?

    The aspirin is to prevent heart attacks when you see that your negative isn't sharp. Grin.

    just a guess, but if it's an aspirin with added vitamin c, it might have something to do with that.

    Are you sure it wasn't Tylenol? You can make a developer similar to Rodinal from acetaminophen, but it involves mixing the Tylenol with lye to convert it to something akin to the developing agent in Rodinal.

    No the claim was asprin, 1 tablet, I guess will buy a bottle along with a power line filter.

    Where's Gadget? Maybe acetylsalycylic acid and ascorbic acid have something in common other than being acids.

    Salycilic acid is Ryuji Suzuki's territory, but IIRC it had to do with sequestering a certain valence of iron that could cause the sudden death of some ascorbate developers. It's hard to see how 5 mg of aspirin in a gallon of D-76 could have any effect on any of its characteristics. I'm pretty sure not even 5 mg of ascorbic acid would have any measurable effect on a gallon of D-76.

    It may be that the science of it was that of putting us on.

    Asprin is acetyl salicylic acid, a derivative of the salisylic acid parent. When asprin decomposes, it forms salicylic acid + acetic acid and that is why bad aspring smells like vinegar.

    Salicylic acid or even asprin may be a complexing agent for iron salts but there are far better ones.

    I agree with Patrick that any effect would be tiny, if there was an effect at all. But who knows, try it! That is what research is all about.

    Aspirin is also supposed to help keep your Christmas tree green a bit longer. Add a couple to the water in the bucket that your tree is is in. If it can keep your tree green, who knows what it can do for your film. Hey, just think what an aspirin could do for digital!
