That is my experience, Henning, and I work exactly the same way, even down to using Photokit for final sharpening. There is a definite difference when you apply the same steps in LR and in PS. Applying the changes as one step of instructions instead of successive steps seems to make a difference. Thanks for explaining it better than I could! Tina Tina Manley www.tinamanley.com
