Thanks for your comments Eric and I keep the idea of using a larger tray than the short'n deep one. I'll definetely need some help during the development to manipulate the print. Before thinking of washing it, I'm trying to figure how to develop it ... :-) More seriously, I'll probably use the sink for washing although it is not large enough to let the paper flat.

I have used trays ; ) Although the small canal/deep tray works OK for some, I though it hard to see the image. working slightly more dilute we did do some bigger images. Flat in part of the tray to get the chemical on the paper then, rolling it up one way, and then the other. I'd adapt to the space available. How do you plan to wash it? I use a tray siphon.

I know the following methods: - roll forth and back the paper in a home-made "canal" deep tray. This one looks ok. - the sponge (let the paper on the floor on a large plastic sheet and apply the chemicals with a sponge). I know some that did it but don't see myself doing it ... - the home-made drum seems unpractical due to its weight Thaniks in advance, Claudio Bonavolta http://www.bonavolta.ch ======= Email scanned by PC Tools - No viruses or spyware found.
