Over the years I have developed a number of different size negatives in
trays using brush development. I use oversize flat bottom (Cescolite) trays
and, depending on size, do one or two at a time. For 5x12 and 7x17, I do two
at a time. For 11x14 and 12x20 I do a single sheet at a time. I have found
the best brush for me to be the Kodak 2" camel hair (?) lens brush. I brush
the film surface completely once every minute. For two negatives, I keep
them separated with one hand, holding down the film I am brushing by the
edge only. Be careful not to touch the image area of the film, as it can
leave a finger (glove) print. I am currently developing in PMK. Tests
have shown that there is no variation in edge density or stain, and never
any streaking. I have never had any scratches processing film by this
method. For 5x7 and 8x10 I still use Jobo drums and have lately been using
Rollo Pyro, especially for Tri X, as it has reduced base fog considerably.
