In this photo, I wanted to create an emphasis on the water. To accomplish this, I used the channel mixer to play with the red, green, and blue channels. I than used the levels selection to enhance the shadows in the photo. In another duplicated layer I brightened the whites. I erased the shirt section to expose the brighter shirt.
