I have been trying out LR3 beta 2 and in a hard drive search for some images to try with the new LR3 RAW processing engine I discovered an image I made in a Colorado aspen grove last summer that had some nice angled back-light. The back-light and strong highlights were a challenge to deal with but after some work both in LR and CS4. Here is the result. I for one am ready for summer!
