Ok, just for reference, I said AfterShot includes NOISE NINJA, not PhotoNinja.
AfterShot also has something called Perfectly Clear.
I keep seeing RAW Therapee as a free download for Mac, but the download is an exe file, R Kelly. Do you like it?
I could run it in VMWare.
I did not know until today that Picasa is a RAW processor (per some website I bookmarked).
There's quite a few out there now. I now have about a half dozen.
