On the M:/ you'll find a PDF tutorial and several source images. Download the source images and complete the tutorial. There are 3 photos you must complete using layer masks.

I prefer you use layer masking from now on instead of using destructive editing tools like the eraser. Layer masking never deletes any of the pixels- just hides them.

Run a 1x3 contact sheet for your edited photos and turn in to the Photo II folder.
