My sister-in-law got married over a year ago, and the disk she bought from her photographer did not include any edited photos (which she was rather bummed about). She has asked me if I would edit a few of her photos for her so she can print them and hang them around her house.
Here is just one of the photo's I edited. It goes to show that even just a little bit of editing can greatly improve the appearance of a photo.
I repeat - I did NOT take this photo (although it is gorgeous and I wish I could claim it), but I did enhance it.
