Green – Edit in Photoshop/Creative Editing

I haven’t found a reason to use the other 2 colors yet, but the possibility is there, like if I wanted to split my Creative Edits (which I mean tinkering with lightroom settings or presets) into one color, and my Edit in Photoshop into another.

Also, Smart Collections is another powerful organization tool with Lightroom 2–it’s as simple as adding a tag to your image, and it will automatically create the collection for you (so instead of color labeling, just create a tag for “Client,” “Personal,” etc. and the smart collection will automatically organize it for you

This is yet another reason I prefer Lightroom to Aperture. Aperture is way sexier looking, but Lightroom gets it done.

I know colour labels are not possible but a quick google search turned this up:

I think this is one of the great secrets of both Photoshop (from CS2 forward) and Lightroom. I work with a newspaper, two agencies and send images to PhotoShelter. Easily keeping track of what’s going where was a nightmare. Back in CS2 days I started using labels for that and it’s been great. Before Lightroom I could open a folder in Bridge and tell at a glance what pics were where. With LR it’s even easier. I have labels for both the agencies, my newspaper, Photoshelter and a “pending” label. Pending are pics I like but which I haven’t quite figured out what to do with yet. I wish there were more labels available to us.

thanks,
