There are many different techniques and tools photographers can use to creatively process their images in the digital dark room. I often use Adobe Photoshop to add texture to my photographs. I use this technique when I want to create an atmosphere, add depth, or embellish an element of my photograph.
Photoshop allows for layers to be blended together through blending modes. You can use blending modes to control and change the way layers interact. A layer’s blending modes can be changed using the drop-down at the top of the layer’s palette.
To see any effect of layer blending modes, you need two or more layers. The blending mode will react with the layer below it. If you have only a background layer, the blend mode popup will be greyed out, as these modes cannot be applied to backgrounds.
One of my favourite blending modes for textures is Screen. The Screen layer creates an effect similar to projecting multiple photographic slides on top of each other.
For example, using a photograph I took of a couple of trout, I’ve layered a photograph of concrete on top of the trout photograph, and set the layer mode to Screen. I also added a Curves Adjustment layer and increased the saturation for a little pop. I think the texture ads depth and richness to the final image.
