I've developed lith film with good luck using two developers - D23 diluted 1:3 and a variant of T/O XDR-4 published by Anchell and Troop called TDLC-3. D23 stock utilizes 7.5 gms of metol and 100gms of sulfite in 1 litre of water. TDLC-3 utilizes 1 gm of metol, 5 gms of sulfite and 10gms of sodium bicarbonate in a litre of water. POTA should work well with these kinds of films (althought I've heard people complain about streaking). Good luck, DJ.(posted 8460 days ago)
