The Importance of Texture in Photography
Texture is an important aspect of photography. It can give your photos more of a 3D look, and change the way the subject is perceived.
I don't mean the texture of the paper you print your photos on, but texture captured in the image. An old person can be photographed to highlight the texture of their wrinkled skin, or they can be photographed with flat lighting to hide this texture and make them look a bit younger.
