    If Ilford Multigrade developer concentrate turns a deep yellow color, is it unusable? I had been away from my darkroom for a few weeks and when I went to make up the developer solution I noticed the concentrate was quite yellow. Altho it did develop my pictures, I am concerned that they will deteriorate rapidly. Should I continue using the product ot toss it?

    If the developer did what it was supposed to do then it is still ok. If you have fixed your pictures properly they should be fine.

    As Hans said, as long as you got an image, the developer has worked fine and will have no effect on print life (all right, you could argue that some of the oxidation products are a problem, but I don't think anyone knows or could make a convincing case).

    Capacity will however be reduced and the developer is on its last legs. You may also find that fresh dev gives you better contrast and deeper blacks.

    Cheers,

    I've used it when it was *turning* yellow, but not when it was fully discolored and dark. I think that as the others have said, if you are OK with the results then you are fine using it, but if you see something lacking it might be a good idea to get a fresh bottle.

    Before you clouse the bottle of the developer, blouw in some air out of the dust-off can. It is a litle heavyer than oxigen and takes its place, so less oxidation.

    Good luck,
    Philippe

    Hans! Thanks so much for the advice. I've only had the darkroom for a year or so and I keep running into situations I haven't encountered before. APUG is wonderful for amatuers like myself! Keeps me up and running. Thanks again.

    Hi Randy - Thanks for your response to my developer dilemma! I've had the darkroom for a year or so, but still run into things that I don't know how to handle. APUG is absolutely wonderful for amatuers like myself. Many thanks...
