LR isn't part of the CS suite. When i bought LR I also bought it with Photoshop which entitled me to a discount as I was buying them bundled together. This offer still applies to LR3/CS5. Go to the Adobe online store to see details.Should I just buy an Adobe CS suite of software?
but the question is, are the viewers of the images going to notice these subtle alterations?
As for choice of the pros?? None of the professionals I follow (blogs) or ones I have met personally use it, they're all LR/Aperture/NX/PS users
