I’m currently reading through Scott Kelby’s book, The Adobe Photoshop Lightroom 3 Book for Digital Photographers. It’s a fantastic book and classic Scott Kelby. In Chapter 2, Scott makes the case for using flags over ratings or colors to sort photos.
On his blog, Matt Kloskowski, agrees and elaborates. He gives us 3 (and a half) Reasons to Use Flags Instead of Ratings in Lightroom. It was enough to convince me.
If you’re a Lightroom user, check it out, and see if you’re convinced.
