Working on the basis that I probably overexposed and under fixed the first roll of Delta 100 I just developed another roll with a shorter development time and a longer fix time. To determine the fix time I put a piece of unprocessed film into the fix solution and waited to see how long it took to go clear. I could see through the film in under a minute. All I have read states that this time should be doubled which would give two minutes fix time. However, working on the assumption that the snow on my images from the last roll could have been due to too little fixing (and that was a five minute fix) I fixed this film for eight minutes. I processed as follows: I developed in in Ilfotec HC (1+31) for 5.5 minutes starting with 10 seconds continuous agitation and then five inversions every minute, used Ilfostop for 30 seconds, then Ilford Hypam fixer for eight minutes with continuous inversions for the first minute and then five inversion every minute, and washed for 15 minutes, adding a little wetting agent at the end to aid drying. Here is a sample of one of the images and, as you can see, the snow is still there. http://www.sclamb.com/temp/Test%20Sample.jpg Can anyone say what is causing this snow on the image? I have scanned many Delta 100 & 400 images on my LS30 and never had this problem, so I can only assume I am doing something wrong in the processing. Thanks again for any advice.
