I like the idea to guide members via video and share tips from spotters experiences with different photo editing programs.
I use Lightroom 3.6 64 bits with, as I think, good results, but only the basic settings and adjustments and the sharpening-effect.
I took me some time to get used to the program since it differs quite a lot from the older adobe photoshop I worked with before. However, in my opinion the results I achieved with Lightroom beat the ones I managed to get with photoshop (7.0).
