I just finished another blog entry. This one is on Aperture 3 Workflow. Lots of people have written about this. I am not sure if many have done it in relation to microstock. As I mention in the blog...this is not necessarily the best work flow but it is the one that I have developed for myself over the past 2 years.
So have peek. Let me know if I have it all wrong, am missing something, or if you have any questions.http://www.bobkeenanphoto.com/my-aperture-3-workflow/
