But now, it does good post-processing as well. I downloaded the testversion, and I must admit that I like it. I think that one can compare it with Adobe´s Lightroom.
I've used it for just over a week now and I can say that it doesn't stack up to Lightroom at all. Lightroom is still faster when working with large libraries, and I've found adjustment brushes to be a lot more flexible and usable compared to the controls in ACDSee Pro.
Haven't tried DXO so I can't comment about that package.
