Crash Course in Exposure Theory

A word of caution is required here. This page represents my opinion only. The concepts are what I'm trying to get across. For more information, be sure to check out the Exposure Theory and More Info pages.

Light - In order for an image to be captured on film, it must be exposed to light. In photography, it is important to be able to measure light. Too much light can ruin a photograph, and so can too little. Light can be measured and controlled by its brightness- (F-Stops) and by its duration - (Shutter Speed).

Film - Film reacts to light. The more light you give to it, the brighter the image will be. You can buy all types of film for your camera, and they will all have a FILM SPEED. "Fast" films are more sensitive to light than "slow" films.

Camera - Cameras come in all shapes and sizes.Three things all cameras have in common are a lens, an aperture, and a shutter. By adjusting the aperture-( F-Stop ) and shutter settings, you change the way light and film interact.
