One of the things I most love about landscape photography is the multitude of ways you can edit any image to produce a wide range of moods and creative effects. This excellent video details six editing techniques a landscape photographer uses to put a more personal touch on his images.
Coming to you from Thomas Heaton, this great video details six common editing techniques he uses on his landscape images along with how he uses them. Of them, I think the two most fundamental techniques any landscape photographer should know are dodging and burning and how to remove distractions. Dodging and burning is a rather basic technique when it comes to how it is altering the photo's information, but it is by far one of the most effective ways to sculpt the elements within the frame and draw the viewer's eye to wherever you would like it to go. On a similar note, understanding how to effectively and convincingly remove a distracting element can make a photo much stronger, especially if there was no way to shoot around the object when you took the shot. Check out the video above for lots of helpful tips from Heaton.
