Use
STYLES to Make a Border
Easy PhotoShop Tutorials
This Photoshop Tutorial will help you to make a border using Photoshop Styles.Styles is located in your tool Pallet along with Colors, and Swatches. If you can't see your STYLES, you need to click on the Styles Tab. If you click on the Styles Tab, and there aren't any Styles there, you will have to load them. So click on the little arrow right next to the Styles Tab and browse to your folder with a variety of Styles.
Make sure your BACKGROUND COPY is selected. If you do not have a background copy you need a new layer so click here.

What
you see in this picture is the BACKGROUND COPY selected. See where the
right Arrow is pointing?
I am picking this STYLE out of my
group of STYLES in this tool pallet. When I click on it, look what happens to
my picture. It created an automatic black border with a drop down shadow. Too
Cool!
Also you can see that the BACKGROUND COPY added the EFFECTS of that STYLE. It added a DROP SHADOW and a STROKE.
What if your Drop Shadow and Stroke doesn't look like mine? Then you need to click the little "f " in the left corner of your LAYERS panel and adjust the drop shadow to 120 instead of 30, and the stroke should be 1px instead of 3px. (which is another tutorial I should start working on)
What happens if you click on some other STYLE? Most of them will totally change your picture to a STYLE which won't work for this tutorial. Now let's learn how to crop the picture with the border.
You can actually click on any area in the HISTORY PANEL and it will take you back in time. So if you make a mistake you don't have to totally start over, or you can click the CNTRL >> Z to go back a step.
