So I was editing photos on Aperture after a recent import. Then I noticed that the dark areas looked as if it was a GIF file, not a TIF. Whatever I tried to improve the lowlight areas, it wouldn't work. Then I reimported in Photoshop CS6. Boom, no problems, no artifacts, almost no noise. But cumbersome as heck. Does anyone else have this problem? Or have I been spoiled by CS6's amazing RAW conversion?
