This is how it changed my picture, using the action.

We then had ago at making our own  'Action'

First we had to open a portrait picture.

Then click on the 'Create new action' button.

Then we named it, and set some function buttons up so that when we wanted to do the same effect to another picture we just had to click those buttons and the effect would happen.
