Photos for advertisement (working progress)

These are some photos I took. I plan on using one of them for my magazine advertisement.

To make the image of Luke look darker, I had to edit the saturation.
I did this by clicking on Image, Adjustments and thenHue/Saturation.
I was then able to make changes to the Hue, Saturation and Lightness.

The result was a very moody, but still somewhat light image of Luke standing with his hoodie on.
