Don't worry, I'm definitely going to try it. I had just noticed a batch of unexpired Scala on ebay and didn't know if I should get some for this purpose or if perhaps other films processed as positives would give a better result. For some reason I thought about the contrast issue. I considered pull-processing for lesser contrast, maybe using a low contrast filter, etc. As you said, experimentation is most likely what is needed. I posed the question hoping that someone else had a tried-and-true suggestion. I'm not there yet anyway, just posing a question based on curiosity. Thanks for the info.
