Can require a lot of chemicals, depending on your tray size. Pretty easy to do, very flexible method - develop one sheet or lots. It was the first method I used and I found I always got marks so gave up that one. Really easy to use but you have to modify them to stop sheets from sticking or from getting marks.

I've used four methods for developing 4x5: Even though I use demineralised water at some stages, I still find it very acceptable being cheaper than the C-41 and specially the E-6 even considering 5 l chemistry configurations. However, I use Rodinal in dilutions over 1+100, and Rodinal by itself is cheap and has a very long shelf life. It has worked wonderfully and the glue, to my surprise, withstands the chemicals - after more than 50 uses they are still glued. I glued 4 rubber doorstops with the proper height on the bottom of the lid and that forces the rack to stay at the bottom. There is just one thing that I had to do after my first attempt with the Yankee tank - the rack that holds the sheets floats with the liquids, specially if it has bubbles, and this can give rise to uneven chemistry being applied to the sheets. In my MF I use AP tanks and inversion at the 10 min. Agitation in these rectangular tanks must be carried out in a lateral fashion and if properly done is equivalent to inversions. Development strategies that are more violent might not be as successful although I must confess that when I tried it, higher agitation that is, it worked very well. I soup my sheets in Rodinal-like developer doing semi-stand development that requires 20 min. Now, since I know that some guys here, LF Forums, really hate the Yankee tank I will shortly explain the reasons why it suits my developing style and works exceedingly well.for me.

B&W film developed in Yankee tanks - they are similar to the OPs tank, rectangular parallelepiped, capable of withstanding 12 sheets and using up 1.6 l of chemicals In my case I regularly use three approaches for sheet development: Regarding the OP, I guess the choice of tank are dependent on the type of development carried out and the film process at hand.

I also do my own developing and printing. In a nutshell my name is Raul Carneiro Martins, I am portuguese, live in Portugal and have a 4x5 field camera, although I am considering getting into the 8x10 in the near future. First of all let me just kind of introduce myself since I am new to these forums and there is no specific forum for introductions.
