I've been trying to come up with a good Aperture workflow and it's been a challenge. My library has grown to a ridiculous size at some 48 gigs or so. I'm going to archive everything older than a year, stick it on a backup drive and start over. I need to make better use of stacks, I think that will help me process things a bit faster. Also I didn't even know about Vaults until today, it's a separate backup system just for Aperture, which is probably a good idea to have.
Anyway, I've put up a few new photos to Flickr and I think they came out pretty well. There'll be more to come as I work out this whole workflow thing.
