I have used Apple Aperture in the past and got disgusted with it because the picture resolution is flat, fuzzy and lacking in color ... compared with other software like Canon Digital Photo Professional and Photoshop CS5.
I recently download some picture pre-process in Photoshop CS5 (which look sharp, well saturated - just great looking pictures) ... for the purpose of making a photo book.
When I view the pictures in Apple Aperture for the photo book, I now realize why I was disgusted with the screen resolution. The good looking pictures from Photoshop CS5 look fuzzy, with the lack of color, etc.
I tried to search for possible screen or monitor preferences, but found nothing that seem to work. The only settings I found was in Preferences>Preview ... I have the Photo Preview set at "Don't Limit" and the Photo Preview Quality set at 12.
I really need help on improving the screen preview resolution in Apple Aperture (Yes I use the new Version 3).
