How to Add a Relief Texture in Photoshop
Computer generated textures often appear flat and lifeless. By adding shadows, the texture appears to pop off the page.
Open a new blank document in Photoshop (File > New). Set the size to 500 pixels by 500 pixels at 72 ppi.
Set the Foreground and Background colors to compatible hues.
Fill the image with the Foreground color (Edit > Fill + Foreground color or Opt/Delete (PC-Alt/Delete or Backspace).
Choose Filter > Filter Gallery, then open the Texture section and choose Grain.
Set Intensity to 40 and Contrast to 50. Change the Grain Type to Sprinkles. Click OK.
Choose Filter > Render > Lighting Effects. Set the Light Type to Infinite.
Set Texture Channel to Red, Green or Blue. This uses the specified channel to create the texture. You can always take a look at the channels to determine which will work best. Adjust the Height slider to fine tune the texture, then click OK.
