Development Stats: Two reel stainless steel tank, invert and twist agitation.
1. No Pre-soaking 2. Dilution mixed from concentrate. 3. Initial agitation for 1 minute then 5 seconds every minute, (2 inversions per minute). 3. Stop with water, four dumps about one minute 4. Fix 6 min TF-4. Agitation 30 seconds per minute 5. Wash 20 min 6. Distilled H2O sprayed on while film is hanging, (works great) 7. Hang dry
Densitometry - Measurements taken from center of negative using Macbeth TD-502. Edge densities greater then center densities. This is a function of the lens. Other lens have different patterns.
