Before and After:

I rotated the photo using the straighten tool in the crop menu and used the camera raw filter to make minimal adjustments to the exposure and contrast of the image. I used the healing brush to remove blemishes from the face and to extend the foliage in the background. I used a gradient map to add a sepia-esque feel to the image so it looks like an old photo. 

Before and After:

I used the camera raw filter to make minimal adjustments and then I used the healing tools to remove people that were in the background. I added another camera raw filter brighten up the skin and enhance the colors of the photo. I used a field blur to keep the focus on my friend.

Before and After:

I first used a camera raw filter to increase the exposure and contrast and to decrease the highlights and shadows. I used the healing brush tool to remove distracting spots on the playground and to remove tree branches. I then added a color balance, vibrance, curves, and selective color adjustment layer to the image to improve the colors and brightness of the image. I grouped the layers into a smart object and added another camera raw filter to brighten the skin of my friend.
