This is an interesting technique. You shot a roll of E-6 Ektachrome super 8 either the Super-85 or the Super-80(Kodak 64T) and then process as if it was color negative. This produces a negative from your film. Then you transfer reversing out the negative and restoring as best you can to correct color. We usually charge $100.00 extra to do this set-up but if you purchase the film from Pro8mm and mention this post I'll do it at no charge.
