http://www.flickr.com/groups/1924221@N25/discuss/72157629528867358/ I developed 2 test strips of Agfaphoto APX 100 for the same times in Fomadon Excel (similar to Xtol) at 23.5C. One strip was stopped and fixed normally in proprietary chemicals. The second strip was stopped with one wash of water at 27C then fixed for 24hrs @ 28 +/- 2 C in a solution comprising 150grams table salt in 600ml water. The tank was kept in a warm cupboard (hot water cylinder) and agitated about every 2hrs except during 8 hrs when it was only agitated once. Conclusion: The print from the negative fixed in table salt solution is entirely satisfactory but held side by side with a print from the proprietary fixer negative it is slightly more grainy. See scans of 0.1 in square sections of negative, processed identically.
