Ancient civilizations developed a rudimentary camera and made many discoveries about light. Years later, around 1430, centuries before anyone suspected it, artists began secretly using cameralike devices, including the lens, the concave mirror and the camera obscura, to help them make realistic-looking paintings. Today we realize that the most basic aspect of photography is the understanding of how light works.

Yet in today's ever-changing technological world, the smart photographer also understands the essentials in his/her field and has kept up with the latest innovations including digital imaging and product developments.

Additionally, the successful photographer knows how to work with several formats, relates well with people, can position an individual or group, and is mindful of the critical features and elements that make up a catalogue, annual report or product shot.
