Hello all... Some of you might remember another thread of mine, where I had problems with the reversal solution. That's sorted, but the dark spot problem persists, so I think a different, aptly named thread would be a good idea. So, let me show you a sample of my latest (3rd) attempt: As you may have noticed, there are 4 dark spots at the sky above the clouds and about 4 more on the water above the boat. I just can't figure out how they form and they're getting hugely annoying, since I generally haven't noticed anything similar when doing normal bw processing. My process is as follows and all steps are at 20°C: 1) 1-2' presoak. 2) 9' development in D19 + 3g/l potassium thiocyanate, agitating 10'' every 30''. Yes, I hit the tank on a firm surface to dislodge any bubbles. 3) 4 water changes with generous, vigorous agitation. 4) Bleach for 7:30. 1g/l permanganate + 50g/l sodium bisulfate. Continuous agitation. 5) Rinse as in step 3. 6) Clearing bath (25g/l sodium metabisulfite) for 3'. Continuous agitation. 7) Rinse as in step 3. 8) Reexposure for 90'' from both sides, 20 to 30cm away from a 75W tungsten lamp. 9) 10' development in D19, agitating 5' every 30''. 10) Rinse as in step 3. 11) Fix in F24 for 10'. 12) Wash. If any of you has any clue, I'm all ears.
