2. Create another layer, call it "rectangle", make a yellow rectangle behind it (select the shape and fill alt+f). Color: #CEBA66.
3. On your pictures layer. Go to Image > Adjust > Hue/Saturation.
4. Now, on your layers tab, create a Layer mask, clicking on that button (a rectangle with a circle inside) on the bottom of the layers tab.
5. Ctrl+Click on this layer to get the selection. Go to the Gradient Tool (Pressing G). And make a gradient pushing from left to the right.
The trick here is that on the mask layer, the white appears and the black not.

7. An example of turning it into a signature or a magazine photo:
