Exposure Calculators to Compare Exposures

The most basic definition of Photography is recording how light is reflected from an object or scene. There are also more artistically oriented definitions, such as:

Photography records the gamut of feelings written on the human face, the beauty of the earth and skies that man has inherited, and the wealth and confusion man has created. It is a major force in explaining man to man. – Edward Steichen

Regardless of how you see photography and its purpose, you will still need to understand Exposure and its components Aperture, Shutter Speed, and ISO – also known as the Exposure Triangle – if you want to have any control over your results.
