I'm considering moving from Aperture to Capture One (or Lightroom), but there are some things that I'd like to know. I tried some noise reduction in both Lightroom and Capture One and the reduction in Lightroom is outperforming Capture One very badly. Noise reduction in Capture One wasn't really visible on the pictures I tried. Am I handling those sliders/options so badly, or is noise reduction just not good enough in Capture One. I haven't find any options to quickly display the master/original image. In Aperture I just had to press 'm' key, and in Lightroom there is a button for on the screen. Is there a feature in Lightroom for perspective transform where you can have those aiding lines in two dimensions like in Capture One? Any reasons to considers Lightroom above Capture One or vice versa?
