I've been working on a general S-curve preset. I've found a pretty basic formula that I like, though it really only works on landscapes and inanimate objects. It's too contrasty for people. I think the curve adds a bit more pop. From the Develop module, In the Tone Curve panel (2nd panel down on the right), I just did the following: Highlights +30 Lights +10 Darks -10 Shadows -30 Here's a shot cropped the same way, but the less contrasty one is LR default. The more contrasty one only has the above applied. This is from RAW on an EPL5 in LR4.4RC. If anyone wants to play with the RAW, and try your own, drop me a PM and I'll send you a link to a dropbox folder, or e-mail it to you (though the file is 14.5MB) What do other folks do for favorite presets?
