For photographers the camera is a tool that is used to record light.
It’s what you use to visually communicate facts or opinions through a photograph.
In order to be an effective photographer and visual communicator It is important that you feel at ease with using whatever camera you choose to use.
You should be as comfortable communicating through your camera as you are communicating through your words. Understanding what your camera does and how it does it allows for an ease of use that allows your “visual voice” to flow freely from your camera.
