This is a nice article Hortense. I have a disagreement with your terminology. A positive image from a mask when combined with a negative will reduce the contrast of the sandwhich requiring the use of a higher grade paper to restore contrast. Therefore the unsharp mask is a contrast reducing mask not a contrast increasing mask. If one would make a print with and without the mask on the same paper grade the contrast will be reduced. To make a contrast increasing mask one would need to combine a negative mask with a negative or a positive mask with a positive. Good luck with your masking.

I did not sufficiently explain the context to this reference. Using an USM it will increase your need to PRINT on a high grade setting. Typically you want a 1-grade increase (or more depending on what you are seeking. Thank for pointing out need for better clarification.

Thanks for contributing a very useful article. I tried USM this summer with varying degrees of success but this makes me want to give it another go.
