I am sure to be in the minority here, but for my medium format activities I have long shot Kodak Tech Pan and I develope it in Ethol. This allows me to rate the Tech Pan @ ISO 100 and the Ethol gives pretty good pictorial negatives. Watch the time in the soup so the contrast does not build up and KEEP THE TEMPERATURE AT 68 DEGREES. I go by the recommended time. The Ethol is much cheaper than Kodak's Tech Pan Developer, but the main advantage is that I can shoot at 2 stops faster and the negatives are very smooth grained.....................piniongear
