One thing I was shown was how to change the info in the metadata tab. I am very excited about this. It's kinda buried, and I was never sure how to add notes. Since I am shooting with different apps on the iPhone that have different filters, I want to note which filter I used. I could use key works but I am not a big fan of them within Aperture. So I was able to find a "Special Instructions" area which I added to my metadata tab. I probably should take a class on Aperture to get the most out of my workflow.
