“the art or process of producing images by the action of radiant energy and especially light on a sensitive surface (such as film or an optical sensor).” www.merriam-webster.com
I teach photography in up to 14 different sections depending upon the grade level. There is substantial overlap in a number of the sections, so understand that any subject you may be seeking may be addressed in another section. For instance elements of light theory are touched upon in Basic Principles, Art History, Design, and Colour Theory, Cameras and Equipment - Functions and Limits, Technical Shooting, and others. Kindly take advantage of the search option or keywords wherever possible.
