Jimmy;(posted 8909 days ago)I experimented with copy film for some time a while back. I believe I ended up using the ethol TEC "A" solution only to tame the contrast. But after using up about 3/4 of a 100 foot roll of kodilth, I gave up and defaulted to Tech Pan. I ended up having an effective E.I. of 3 and still lost detail in the shadows. I currently shoot tech pan in 35mm and develop in Diafine, the "A" solution for 3+ minutes as per the instructions and exactly 60 seconds in the "B" solution. TEC in the two solution fromula also works and is a lot less $ than Technidol.
The added bonus to Diafine and TEC development is I get an E.I. of 100, which makes tech pan a general purpose film for many applications. 16x20 inch prints look very good.
