Erik – thank you for jumping in. I was going to suggest the same thing.
David – Though the names are the same, the underlying RAW Power H&S algorithm is different than the one in Aperture’s H&S. Most of the filters in Aperture are private to that application, so there are not available for me to use.
Deepen and Lighten are different from either. One of the key differences between those and either of the H&S filters is that Deepen and Lighten maintain contrast (among other benefits) which keeps images from becoming washed out.
