I was playing with the latest beta of lightroom (fantastic, btw) and visually the results seemed to be far superior from past experiments with my p65 files. I couldn't detect the problem of the image being divided into fourths with each section a slightly different density but didn't try printing any of them.
Anyone care to comment? I've been converting to DNG and using LR (I'm terrible with C1 ... user skill not software problem), just curious about the current status here.
