Ok, so I've made the leap and have decided to go full out with a color printer (Pro 9000 Mark II) and colorimeter to print out my photos at home from Aperture 3. However, I'm having a mess of a time understanding how it all actually works together. If anyone know of a WELL-WRITTEN explanation of color spaces, profiles, proofs, and their interactions with each other I would like that because I can't seem to find one. Specifically, this is my current setup: 1. Import images into Aperture using sRGB profile 2. May do light edits in aperture or heavy edits in CS5 but always retaining sRGB profile on export/import 3. I'm using a software-calibrated monitor (Acer H233H calibrated profile I believe I called it) Now, how do I calibrate my monitor and then which settings do I use to print to my printer: 1. I want to get an external colorimeter -> does this replace my Acer H233H profile for my monitor? 2. When I print from aperture do I choose the printer profile or my monitor profile? A somewhat unrelated question is what are people's experiences with the eye-photo display 2 vs. the spyder 3 colorimeters?
