Dune trees - Rotate image tutorial

Dune trees, originally uploaded by foto-art.

Trees near the beach at Formby Point. This little group of trees stood a little in isolation from surrounding trees and they stood out to me. I like the contrast between the softness of the grass and the hardness of the trees, and the complimentary colours of the grass against the sky. if I was going to do anything else to this, I would increase the colour saturation to make that contrast of colour more effective using Photoshop in Image/Adjust/HueSaturation. What is important in this shot is that the trees are vertical. The slope of the grass bank tends to make us compensate when taking a picture like this so that the trees end up at an angle. If this happens, it can be corrected in Photoshop using Image/Adjust/Rotate canvas/Arbitary. A value can be added here of say 2 or 3 degrees and the image can be rotated clockwise or counterclockwise to get the trees vertical. The image then has to cropped using the crop tool to restore a full image without angled backgound tone.
