Uneven 8x10 Negs in Pyrocat-HD

[Jay DeFehr]

For the absolute ultimate in even development, I recommend brush development of one sheet at a time. This method doesn't require an excess of development solution, or even oversized trays. You can even process in a single tray, using the developer one shot. The downsides are the tedium of working in the dark, and the time required to develop one sheet at a time. For me, this method is best suited to large sheets of ortho film, but it works with any size and sensitivity. I think the method was introduced by astrophotographers who used glass plates, and require absolutely even development. Brush development works very well with intermittent agitation.

Jay - I actually considered experimenting with brush development but figured that it might be difficult to be consistent in developing to a specific CI. It's a great idea though, and would warrant a brush width wider than a few inches I imagine. Thanks!

Good luck, Mike!
