CANVAS COLOR QUICK CHANGE

In previous versions of Photoshop, before you went to the Canvas Size dialog you had to choose your Background color first, and if you didn't have it set to white, you'd have to do the old "cancel Canvas Size, set your Background color, go back to Canvas Size" routine. It was brutal. Luckily, in Photoshop CS you can now choose your canvas color from right within the Canvas Size dialog. If you want a white canvas (which is the most common choice) you can choose it directly from the pop-up menu at the bottom. If you want a different color, just click on the Color Swatch.
