Hi to all. Until it became near impossible to get in Australia, I have been using Aculux-2 for 4x5 negs. Today I mixed up a fresh batch of X-Tol (5 litre kit, expiry date 2006) to do some film tests with HP-5 Plus and FP4-plus. All films were in deep tanks on Kodak 4x5 hangers, lifted three times per minute as per Ilford instrucions. I also tried a higher degree of agitation at later tests- it didn't make any difference to the problem,WHICH IS- the tones set on Zone 7 or above come out normally i.e dense,(well actually a bit lower than I wanted, but I was running development time tests) but the lower Zones are reversed. They look as though I'm viewing a slide film, not a negative. I have not had this before with Medium or 35mm formats and X-Tol. The film borders which should be clear are also very dense (as though fogged) but this doesn't carry through to the whole image, otherwise I wouldn't be able to see anything on the neg. Any suggetins would be appreciated. Mike
