The crop tool allows you to remove portions of an image to create focus or strengthen your composition.

The wind filter places small horizontal lines in your image to simulate a wind-blown effect.

This filter adds randomly spaced ripples to the surface of your image so that it looks like it's underwater.

A layer mask is used to hide portions of a layer and reveal portions of whatever layer is below it. You can modify the mask by using the brush tool and painting in either black or white.
