Lightroom is amazing for ever so many different tasks. But without a doubt, the presets in the develop panel are the most fun to experiment with. (please ignore my ending a sentence with a preposition. so wrong. i know.) Below & first is my SOOC image. Following the SOOC image are numerous one-click presets. If you mouse-over the picture you'll see the preset that I used.
In this post I have a list of helpful Lightroom links, including some of the places where I've found my presets.
