Exposure: This is the amount of light your camera sensor or film receives, and is mainly controlled by three systems. Aperture (f-stop): This determines the maximum aperture of the lens. A larger aperture (smaller f-number) lets in more light and creates a shallower depth of field, which means the background is blurry. A smaller aperture (large f-number) lets in less light and a deeper depth of field, which means more focus on the area. Shutter Speed: This determines how long the camera shutter stays open. Faster shutter speeds (e.g. 1/1000 second) stop motion, while slower shutter speeds (e.g. 1/30 second) can blur movement and create a sense of movement ISO: This measures the sensitivity of the sensor to light. Low ISOs (e.g. 100 or 200) are used in bright conditions and produce little noise, while higher ISOs (e.g. 1600 or 3200) are used in low light conditions but can produce more noise yields (granularity). Composition: This is about organizing objects in your photo to make them
