    Looks kinda like a close fit to me. If I only do single sheets it should be fine. I will probably get one and try it.
    Thanks for all the comments.

    I've increased the dilution of my developer to give me more liquid in the trays without using more developer. Using Pyrocat, I dilute 1:1:200 instead of the recommended 1:1:100. Then increase the development time to compensate.

    I also use the "8x10" trays with Pyrocat and D-76 and have never had a problem.

    Use plastic drop cloth and a 2x4. Cut the 2x4 to width and.or length. Put the 2x4 in the tray and lay the plastic drop cloth material over it. Will make the inside dimensions smaller so you use less chemistry. Having the roll of plastic drop cloth means you use it and throw it out if you want. Got a sheet 12 x30 feet for $2.00 on sale at WalMart last week.

    Makes it easier to use larger trays so you don't have to keep a number of different sizes around.

    The reason the same size tray as the negative is not recommended for developing negatives, is that there can be more agitation happening around the outer edge of the negative than the center of the negative (uneven development). A larger tray avoids this -- but as noted, good results are possible with the smaller tray -- agitation might need to be closely watched until one finds the best method.

    B and H stocks 11x14 trays by Kalt, Yankee, Richards, Arkay, Doran and Cescolite.
    I don't know why they'd sell you 12x16s if you asked for 11x14s.

    Alternatively, you could shop for kitty litter trays at Target or The Dollar Store (and take along a tape measure.)

    If the goal is to safe chemicals, the best way to go is to use tubes. These are dirt cheap on the used market, and pretty inexpensive new. For an 8x10 negative or print, you only need about 1.5 oz. of chemical. This will vary slightly by manufacturer. The more important thing is that every negative or print gets completely fresh chemicals and their is no need to try to adjust, somehow, for exhaustion. PLUS, you end up saving a lot of darroom space AND you can work with the lights on, to boot!!!

    put a 12" piece of 1x2" pine under the back end of the tray so your solution tips toward you.

    If you insist on trays, you can buy a ton of them in any size, basically for the cost of shipping on EBAY, etc. You can't do much to damage a plastic tray, although you might need to clean it out with a little bleach and elbow grease. I've got trays from 5x7" to 20x24" and I basically got them all for pennies, BUT:

    As I always say, "Once you try tray, you never will stray"

    I never knew this - I always thought it was recommended as a way to lesson the risk of scratches (easier to shuffle thru the stack of negs).
