I have used it. I am using Light Room so that is the reason In not using Capture now. It does a great job with Ricoh DNG files. It may be the best for Ricoh DNG files. Capture can extract details other processors don't even see. There's a guy named Mitch Alland that is using it now. He seems very happy and is a good, trusted shooter.
I may have spelled his last name wrong and I wont say what forum he hangs at, because it's not polite. You can find him easy enough. Don
