Photography Exposure Basics

It's good from time to time to review the basics of how a camera works and the adjustments you have at your disposal. So many people go around taking pictures with their cameras set on automatic. Modern digital cameras do a fantastic job in point-and-shoot mode, but there is a whole world of creative opportunity for those who take a few minutes to explore the features. There's even a formula that describes the whole process: H=Et. Where H is the luminous exposure, E is the image-plane luminance and t is the exposure time in seconds. Perhaps a more practical explanation might help.
