    Re: Dark Clouds on Negative Development

    fwiw, I used to Permawash my negs but have stopped doing that. Think over the years, the consensus what that it wasn't necessary, with a proper longish wash. When I wash in the Expert tank, I do a number of exchanges, similar to the Ilford method of fill and dump. I'm also looking at starting to use hangers and wash with a Gravity Works washer, but at low flows.
    notch codes ? I only use one film...

    Thank you Fred. That helps provide another reference.

    Here's a good thread on film washing. https://www.photrio.com/forum/thread...ng-test.69416/

    Greg Davis has done a number of tests. You can decide which method suits you best, but the bottom line is you need to wash film 30 minutes if you don't use a hypo-clearing agent (which, BTW is not recommended for staining developers) or 15 minutes with a hypo-clearing agent.

    This ends up being slightly more (five minutes more) than Ilford recommends.

    Have fun,

    Doremus

    Thank you very much. I am religious about the use of hypo-clearing agent but I will look at that link.
