This stuff is FujiLith Ortho Film, Type L LO-N100. Does anybody out there
know if this is still available, and in what sizes, and how much? The stuff
I have is eight years old. I hope its not discontinued.

Dick, I used Rodinal because I had it on the shelf. I wanted to do a
quick check on how this film performed. I started with Rodinal 1:100
knowing that I needed to greatly reduce the contrast curve of lith to give
continuous tone. This was too flat so I increased the strength until I got
what I wanted.

Once I had a good positive, the reversal part was your idea. The bleach
formula is pretty common to many proceedures I had been reading about. I
tried to redevelop in the same developer (Rodinol) but I got poor density,
so grabbed some Ilford MG paper developer and used it 1:3, again, because I
had it on the shelf.

Normally I mix my own developers but beacause I had no idea what this film
would do I wanted to quickly determine its usefulness.

I also have some Kodak Accumax AL17 line and plotting film 16 X 20. I
haven't tested this yet, but the fellow who gave it to me tells me that it
should be even better that the Fuji. Has anybody used it for alt process
negs?
