Guys A little advise. I have been using Nik Software suite in Aperture now for 6 weeks and it's fantastic! But it is missing a way to say remove a complete blue sky from a photo and add one back that has some interest.. I know you can do this with PS but to be honest I haven't the time for the PS learning experience.....and I really like Apertures work flow anyway. Been doing research and came across OnOne's Perfect Mask 5, which seems like it would do the trick! Any comments, personal reviews, pros/cons people have got? this is from Silver Effex!!
