Hi,
I have a question concerning the difference of bleach bypass on the print vs. the negative.
As I understand it the effect of skipping the bleaching is most apparent where most of the silver is developped – the highlight areas in the negative and the shadows in the positive.

On tests with various stocks I saw, the effect looked extremely similar on both types: Increased contrast, desaturised colors, deep blacks and blown out highlights.

How is it possible that the areas not containing metallic silver – the highlights in the positive and the shadows in the negative - seem simlarly affected?

Thanks
G.L

Do you know the test parameters? Perhaps the film was exposed to compensate some for the bb effect which would tend to blow out highlights if the bb is on the print or block up blacks if the bb is on the neg.
