    12X16 developing trays

    I wanted to buy 11x14 developing trays from B&H but they didn't offer them by Paterson, and had the 12X16 on special. So I bought them to develop my 8X10 negatives. Alas! They work fine but you need at least 2 liters of liquid for me to feel comfortable keeping the negatives covered. I only developed 4 negatives and since this was my first time with 8X10 and using D76, I wanted to use it as a one shot process. So I wound up discarding a lot of chemical. Does anyone else have this problem or what do you do?
    Thanks in advance
    Jim

    B&H is inconsistent in how they describe the trays. Some are described by the print size and some by the actual size. A 12x16 tray is for 11x14 prints. An 8x10 tray is actually 10.25x12. You need the Paterson 8x10 trays.

    You could just get one 8x10 for developer and use the larger ones you have now for stop/fix/wash.

    The reason I wanted 11x14 is after reading Ansel Adam's "The Negative" he says use the next size larger tray. So that is what prompted my search.

    Does this mean dispose of the developer and save the stop and fix?

    Paterson is a UK company; they offer 12x16 trays because 12x16 is a standard paper size in the UK.

    Perhaps look for a flat bottomed tray and develop one sheet at a time? That way, you shouldn't need too much developer. I use a non-stick oven tray for 8x10 film myself. It's about 10x12" I think; large enough to leave a substantial margin between the edges of the film and the walls of the tray.
    I find the standard ribbed processing trays virtually useless for anything but washing.

    Curved bottom trays such as the old Heath Color Canoe enable developing one sheet of film at a time with very little developer. The 8x10 Color Canoe works fine with less than 2 ounces of developer. A pre-wash is advisable. I've switched to liquid concentrated developer such as Kodak HC-110 or T-Max to permit mixing a barely sufficient amount of one-shot developer.

    Those trays are 8x10 in size -- too small for 8x10 negatives, The 10.25 x 12 is the size box they come in. Just buy or find an 11x14 tray...a 10x12 will work fine, also.

    Here is a photo of an 8x10 sheet of paper in a Paterson 8x10 tray. You may or may not want more room around the edges depending on your method of agitation.
