Colour adjustment tutorial

For part of the natural forms project involving Andy Small & colour in particular, I have put together a tutorial demonstrating how students can adjust colours in their images in both Photoshop & Pixlr. This is the Photoshop copy along with a final edit. The tutorial for these editing techniques in Photoshop & Pixlr are quite similar, whereas for previous edits the techniques have been different.

 Above is the original image (yellow background) and the edited photograph (turquoise background) achieved by editing a selected area of this image.
