Texture photography is all about finding and shooting patterns, details, color and depth. Sometimes in the most boring places! Textures are everywhere. They can be discovered around, in and on everything.
ISO is your camera's sensor sensitivity to available light. The ISO setting on a DSLR or mirrorless camera controls this sensitivity. Along with APERTURE and SHUTTER SPEED, it makes up the exposure of any photograph.
Shutter Speed is the amount of time your camera’s shutter is open. This allows light to pass through to the sensor. It's measured in seconds or fractions of a second. Together with aperture and ISO, it makes up the exposure of any photograph.
Aperture is an opening on your lens (a small hole) that light travels through. There are aperture blades that can be controlled using the aperture dial on the back of your camera or sometimes on the lens itself.
