Elements of Photography:
The use of lighting to bring out details of an object, making it easy to see whether a surface is smooth or soft. How things look like they feel.
Texture represents the details that are present on the surface of an object. You can use texture to create photographs that are visually interesting.
Direction of light plays an important role in bringing out the textures. Based on the mood you want to convey in your photograph, you will either wait for the light that will emphasize the roughness or softness of an object.
