How do I preserve my layers and or my CMYK color space when using Sharpener Pro 3.0 in Aperture?
To preserve any information created in an external editor such as layers or a non-RGB color space, please use “Edit a Copy With” and then select Sharpener Pro 3.0. To access “Edit a Copy With” simply hold down the option key on your keyboard and then access the Images menu and select “Edit a Copy With” This will create a new version of the previous version that was already altered in an external editor.
