Saturation and Masking Example

To saturate this photo I added a layer by clicking the black and white circle in the bottom right corner. I drop down menu appeared and I chose "hue/saturation." Then I moved the slider labeled saturation to 50. To mask the photo I chose the brush tool on the left tool bar. In the bottom left there was a black square and a white square. I used the arrows in a corner to switch the dominant color to black. I made sure I was using 100% opacity in the tool bar and that the mode was normal. I began moving my cursor over the girl because I did not want the saturation to affect her. I was careful to only move over the girl. To do the edges of the girl I lowered my brush size. I used the zoom tool on the left tool bar and clicked where I wanted to start doing the edges. I clicked back into the brush tool and began moving my cursor around the edges of the girl making sure to saturate her fully without undoing the saturation of the background. I used the backslash key so where I had gotten rid of the saturation was highlighted red. I use this to make sure all of the girl wasn't saturated and the background was still completely saturated. If I had taken away the saturation where I didn't want to I used the arrows in a corner in the bottom left corner to switch the brush tool to white. I ran my cursor over where I wanted the saturation back. When done I used the arrows in a corner again to switch back and remove more saturation where I wanted. Using the brush tool and zoom tool I worked around the entirety of the girl until I had gotten the result I wanted. Then I clicked file, save as, and saved it as a JPEG image.
