Understanding how images are created in your camera is important to understanding how the final image may appear.

Learn to use the different focus modes available in your camera.

The goal of exposure is to accurately render the tonal values of the scene you are photographing.

In addition to rendering the correct tonal values in an image the tools that we use to control the exposure (ISO, aperture and shutter speed) have an impact on the final image. We can use these tools to improve the quality of the image, control depth-of-field and to freeze or blur motion.
