Learning how do use 'Photoshop'

I learned to use the program 'Photoshop' in fridays lesson by another member of my practical group. This is a great benefit to our practical and technical work, such as, producing a film poster which i can now edit photos and other images. Also our web page for our teaser trailer, where film stills will be necessary to upload and edit.

-Click 'file','new', then 'image from clipboard'.
-Right click on small image in the right hand corner
-Click 'Duplicate layer'
-Click 'Enhance' along the tool bar
