Advertisement (Gone after free registration)In the excitement surrounding the LR2 release (it is an fantastic upgrade to LR1), I wanted to pass along some links to Lightroom Presets.
Presets -- exuse me if I am repeating old info, but I only recently discovered their usefulness -- are user-generated settings (curves/clarity/sharpening, etc) designed to give a specific look ("old time black and white", "dramatic colors", "awsome sky") to your pictures. Some are very useful, some not at all, but, at the very least, presets give you quick "ideas" on getting creative while processing photos in LR. In the develop module, you can preview them, apply one to a photo, and tweak it to suit.
