Mark and Kaye, sorry about being so late in responding!
Mark, I upgraded to Lightroom 5 to learn some of the new tools available in 4 and 5 such as the improved Basic Module.
Kaye, I don't see enough improvement in CC over CS5 to warrant a monthly 'tax' to use the features I paid for in CS5. That will likely change down the road but for now, the improvements in Lightroom did entice me to upgrade from 3 to 5.7.
Somewhere I was asked if I had a photo of the inside of the Lockheed SR-71 Blackbird cockpit similar to the one in my Avatar. A pilot friend of just sent me this shot.
I am hoping to get back to my Project 52 images soon!
