Hi Neal,
Thankyou for your kind welcome, in actual fact I no longer have a dark room facility, the space that I used is now taken up by the computer that has replaced the enlarger as explained in my first post. I am totally committed to film developed in two bath developer because it scans in on a high grade scanner (Epson 4990) so well! The image quality that I can get completely blows away digital, but also I like to use traditional cameras as I find them so much more satisfying to use, mostly 35mm in the past but am now moving into medium format.
As for lith development, this is no longer possible in the particular way that I used it, as the paper has since been re-formulated to remove the heavy metals from the emulsion, also the developer that I was using has ceased to be available.
Stephen.
