Jorge: I hoped you'd respond to my answer to P. Krentz. I think ther's some confusion here. As I read his Forum ?, He indicates that he is testing an ASA 25 film under the enlarger and further cites P. Davis's Delta 100 exposure at EV 3.4. His ? is what is the EV exposure for ASA 25. You're correct that more exposure is needed and my direct answer is An EV of 5.3 or 2 stops more than that for ASA 100. I didn't get that direct answer from your response and thought you were suggesting he expose the film at EV 1.4. Hope this clarifies the issue. Regards, Ben Wilbur
