Jack Davis, co-author of the Photoshop WOW! and and How To Wow: Photoshop for Photography has teamed up with onOne Software to release a free set of Develop presets for Photoshop Lightroom. This is a sizable collection of presets varying from basic tonal correction to B&W conversion and vignetting. Since they are presets, you can modify the settings once you have applied them. Not only that, it’s a great way to really get familiar with how Lightroom works. Just apply a preset to different images and then study the settings for each. It’s definitely worth checking out.
