Start Photoshop. Navigate to the layer styles files on your hard disk and right-click/Option-click, then select Open. Photoshop automatically loads the style set.

A lot of Photoshop problems can be fixed by dumping the Preferences file. While launching Photoshop, hold down Alt+Ctrl+Shift on the PC or Cmd+Option+Shift on the Mac. When asked to reset the preferences, choose Yes.
But before you do this, save your custom Patterns, actions, styles, brushes, gradients, shapes, and color palettes. These will also be reset, and you don’t want to lose them forever. You can even create an action to do this, so you have a one click backup! (Don’t forget to save the backup action first.)
To change the color of an image, press Cmd/Ctrl+U to open the Hue/Saturation dialog box (Figure 1). Then move the Hue slider to change the color. Use the Saturation control to adjust color intensity, and Lightness to adjust… well, the lightness. Click on Colorize to add color to a grayscale image or to add a duotone effect to an RGB/CMYK image.
You can incrementally adjust a highlighted option box value in just about any dialog box by pressing an arrow key. Press the Up or Down Arrow key to raise or lower the value by 1. Press Shift-Up Arrow or Shift-Down Arrow to raise or lower the value by 10.
Palettes are often in the way. One method of quickly moving a palette out of the way is to send it to the edge of the screen. To do so, press Shift and click the palette’s title bar to snap the palette to the nearest edge of the screen, away from the centre of the image window.
When you are making a new color gradient and you want to use the same color more than once, don’t recreate it. Just hold down the Option/Alt key and drag a copy of the slider.
