This would allow one to fill the tube with developer and have the film lying about half and inch or so below the water level. Screw on the tube cap and start the development procedures accordingly.

    I made an error in my previous post - my 5x7 slosher tray holds 6 sheets of film - not 4. Sorry!

    My 4x5 and 5x7 slosher trays are Summitek Cradles:

    http://www.summitek.com/cradle.html

    They are very well made and reasonably priced (less than $50.00). Summitek does not list an 8x10 Cradle.

    My 8x10 slosher tray is made and marketed by Photographer's Formulary. It is of equivalent quality to the Summitek Cradles and the price is in the $80. - $90. range - as I recall.

    To confirm my understanding, it's not a good idea to do this with four sheets of 8x10 stacked up in an 11x14 tray, right?

    It wont work Max. Uneven development will occur as the top ones are forced upwards and out of the developer by those at the bottom when you leave them to stand.

    Thanks.

    I'm going for a record here with stupid questions - I don't have room for slosher trays. Is it just that the top ones won't get even development or that the developer between the sheets gets exhausted?

    In other words, what if you put a few "dummy" sheets of already-developed, fixed, and washed film on top to keep the others down?

    I know, I could always just do one sheet at at time, but I'm just asking...

    You are asking for problems. Trust me I tried with two 5x7 negs just to see if it would work and what a mess. Don't try it. With one tray you are limited to one negative for this, and that is not bad as long as you don't mind sitting in the dark far a long period of time.

    There are no stupid questions!

    You can process 6 sheets of 5x7 with one 16x20 tray and 1 5x7 slosher tray that fits inside it.

    1. Pour 2 liters of tempered water into the 16x20 tray, insert the slosher tray and pre-soak the film. Then add the developer concentrate to the soak water and agitate for 30 seconds.

    2. At the halfway point, agitate for another 30 seconds.

    3. When the development time is up, pour the necessary amount of non-hardening fixer concentrate directly into the developer and agitate (this is a Pat Gainer trick and it works very well).

    4. Dump the used developer/fixer and wash the film in the slosher/16x20 tray combo, using multiple changes of water. The wash water needs to be within a degree or so of the soak/development/fixing chemistry - AVOID THERMAL SHOCKS!

    If you are contemplating stand/semi stand development of large format negs then I would recommend tubes. It is documented on APUG and other places how to build them and it is very simple and cheap. Plus you can work with hte lights on for most of the process. I use them for 4x5 semi stand with pyrocat sucsessfully

    I'm pretty sure that BTZS tubes (at least the 4x5 tubes I have) are NOT made this way. You must agitate fairly often (roll every 10-15 seconds at the least) or you get nice lines on your negative. I get this effect even when overfilling the cap as much as possible. Though I suppose you could fill the entire tube with developer if you wanted, but that defeats the convenience/purpose of the cap.

    Just a warning to those who might try it....

    That is exactly what Fancesco was saying. You fill that sucker up. I have been hesitant to do it this way because of the huge amount of fixer it would require.

    The slosher idea sounds pretty doable though.

    I hope you don't mind if I add a question to this.

    I have been told that you need to dilute the developer more than normal. Is this true and how much.

    Heck if the negs aren't moving I am not screwing them up.
