Happy New Year to all my readers!

Let me start the new year with a very simple diagram; one that is at the basis of all exposure:

There are three, and only three, variables that define how light or dark your image is. ISO, shutter speed, and aperture. Get that straight and you can start using the camera, knowing what it is doing and why. Want brighter? Increase ISO, use slower shutter, or use larger aperture (lower “f-number”). Darker? The opposite.

In the  next year I will continue to mix basics like this with advanced techniques, often centered around flash and creative light. Keep reading and keep learning – and keep having fun!
