You just took your 13-month-old granddaughter Madison (and her mommy and daddy) out to dinner at a Japanese hibachi restaurant.  It was Madison's first experience with the sturm und drang of Japanese hibachi cooking, and here's a peek at some of what happened:

The little inset image is created, of course, by making a rectangular selection (with zero feather) of the granddaughter, pressing Ctrl+J to turn the selection into a new layer, and then pressing Ctrl+T to enlarge the new layer and move it to a desired location.  No mystery there.

Nor is there any mystery about how to create the white stroke around the new layer.  But if there's one thing that SONOPP photographers really want to do, it's to use Photoshop as efficiently as possible, with the fewest number of operations.  Each keystroke or mouseclick costs time in production mode, and SONOPP photographers want to be one-click experts.

Looking at the layer closely, we can see that the stroke is white, about 8 pixels wide, and positioned inside rather than outside so that the corners are square rather than rounded.  None of these are standard default values for a stroke.  So how can it be accomplished with one click?

Easy: create a Stroke Style.  Start by making a layer and giving it a stroke.  Select a color you use often for strokes, like black or white.  Select a size you use often, say 8 pixels.  And select the position you use often, like "inside".  Don't click OK yet.

At this point the stroke Layer Style dialog should look something like this:

See the third button labeled New Style... in the top-left corner?  If you press that button Photoshop will take all your settings and preserve them in a new Layer Style:

Here you've named it "Stroke, Inside White" and checked the box to Include Layer Effects.  (You need to name it appropriately because every Stroke Layer Style gets the same dark icon, with a faint whiff of the default values.)  Here's what the Styles palette looks like now:

Well, no, it doesn't look like this right away.  The new Stroke Style will be at the bottom, and maybe you don't have your styles displayed this way.  (If you just have the icons showing it's hard to tell one Stroke Style icon from another, or from any other icon for that matter.)

So how do you get the list looking like this, with the new Stroke Style at the top?  Well, first you click on the little flyout menu icon and on the menu that appears, check "Small List".  Then click on the menu icon again and select "Preset Manager...".  The Preset Manager dialog will pop up, looking like this:

 

Using the mouse you can drag any little square to a new position and it will stay there.  Here the new Stroke Style has been moved to the upper left, i.e., to the top of the list.  Click "Done" and your Styles palette will have a new appearance.

And you're a One-Click champion again!  Next time you create a layer that needs a stroke, just click on your topmost layer style and it's there!

Obviously if you have several different strokes that you use a lot, you can make a layer style for each of them and add to the list in the same fashion.  And once a stroke is added, it can be altered from the Layers palette just the same as always.

Enjoy!
