Has anyone else tried this? I have six converters mostly freeware, and I've run the same images through each using the 'default' processing. Then I viewed them on the same organizer. They are: Xnview, Raw Therapee, Pentax Lab, the Adobe that came with PSE3, RAW Shooter, and Picasa2. I also used LightRoom but now that it is out of Beta, I'm not going to use it (it wasn't the one I like best). Adobe, RAW Shooter, Picasa2 all were exactly the same. The Pentax Lab was really good but just a little light. The top two in my opinion were XnView and Raw Therapee. They were both a little dark but had a richness that I liked (very much). When I adjusted the light converters (darker) and lightened the the others, my personal favorite was XnView, but I can't figure out how to get 16bit TIFF file so by default RAW Therapee was my top pick. I enjoyed this test and now have a converter that I like.
