I made this image 13 years ago in the Lower Antelope Corkscrew Slot Canyon near Page, AZ. The canyon walls have a unique appeal that comes from their texture. You can use texture either as a main subject or as a compositional tool.
Why does texture matter? It lends a dimensional quality to photography. Since photography is a 2D medium and we live in a 3D world, photos that show texture have a particular appeal.
Here’s a trick to working with texture. Look for side lighting or light that comes in at an angle (as is the case with the slot canyon photo) to increase the viewer’s awareness of texture.
