Tutorial 1 (Page 2): Playing with Layers and Layer Modes cont...
Setting up the document
Start off by opening the image in Photoshop. It all works exactly the same as other programmes. (File >Open - find the image where it is saved on your computer and select it).
Make sure that your Layers palette is open and positioned where you want it.
(Window >Layers - you can drag the title bar to move it so that it is positioned comfortably for you to access easily).
Another important palette that you may need for this exercise is the history palette. It is really useful for stepping back stages if you want to delete a few of your most recent moves.
(Window >History).
Double click on the highlighted layer in the palette entitled background.
A 'new layer' window pops up, as shown in the diagram above, select the OK button. (this converts the embedded background image into a layer called 'Layer 0' and unlocks it - you will notice the little lock icon on the right disappears).
