Few days ago I borrowed a pen tablet to edit in LR3. I often have to dodge and burn the pictures taken with my D300. The problem is that it is difficult to use mouse to follow the various shape / contour of the object. For some pictures such as landscape photos, I can just apply a GND filter effect to it. Using a pen on tablet greatly improve the editing experience. It is so natural like hand drawing.
See the difference ? But still.. I have problem with the edge of the object. I have to edit them very carefully to avoid aberration like effect.
