Editing Images in Post

For our final photography lesson this week, we're going to talk about the final step: editing your images. We'll take a look at different kinds of techniques for color correction, touch ups, and a few other fun effects.
This lesson is really more of a roundup than anything because we've covered tons of photo editing tips and tricks in the past that it would be kind of redundant to re-write them all here. First things first, we have entire night school on Photoshop, including a lesson on color correction and touch ups, so you might want to start there. If you're looking for more, here are a bunch of handy tips and tricks to get your photos into shape.
Note: A lot of these tips are demonstrated in Photoshop, but not all of them are and many can be replciated in other (cheaper) image editors.
