I have 35mm colour negative image that I am trying to print onto strips of colour transparency film. My background is in filmmaking so I am using 35mm motion picture colour negative film and printing onto 35mm colour positive film, processing with ECP 2D. I understand these materials and do not have a problem. However, I am not a photographer so I do not have much darkroom experience. The enlarger I am using is a Beseler that does not have a colour head. What I am trying to achieve is to enlarge the 35mm original onto strips of 35mm positive that are butted together on the easel; this produces a large positive image. I am using CC filters in the enlarger but not any contrast filters. I put black paper on the easel so light does not reflect through the base of the film. My problem is with the exposure times. Sometimes the prints are too dark or light but it is never perfect with good contrast. How can I fine tune this process to achieve better results? I know this is an alternative process so maybe i cannot get good results? thanks for your time! oh and any good books or links would be great!
