Images of textures have many uses in post processing. Perhaps the easiest way to use them is to employ them as backgrounds in glamour composites. Here are a few examples with model Tiffany Felisha. It is readily apparent that adding a slightly blurred drop shadow makes it appear as though Tiffany is standing in front of a colorful wall:
If a fun, surreal background is chosen as in this example, a drop shadow should not be used. After all, it's surreal:
Some textures look good in black and white. In this example, the drop shadow has returned. This image was converted to black and white using Nik's Silver Efex Pro 2. A White Frame vignette was chosen before hitting the OK button:
The first three textures shown above were purchased from Mark S. Johnson - a true Photoshop guru who is one of my heroes. To me, his images are so very evocative. His website is: http://www.msjphotography.com. Of course, anyone can compile a library of textures. One of mine is shown below. I chose it because the colors matched Tiffany's top. However, they matched so well they competed with one another, so I desaturated the textured background quite a bit using a Hue/Saturation adjustment layer:
Textures are an easy way to add interest to any glamour composite. They can be rotated, darkened, lightened, stretched, desaturated, supersaturated, blurred, altered by blending modes and even layered using different layer opacities. Start building your texture library today!
