• To use, simply place the graphic you would like to displace in Photoshop. Apply the "Displacement" effect, choose your desired amount by changing the "Scale" parameters, then select any Liquiform map to apply the effect.
• Please note, the scale of your graphic will change the look of the effect. These maps are 3840x2160 resolution, and will work best with your graphic scaled close to that size.
