Beginner's Guide to Photography
Introduction to Exposure
Even if you leave the calculations to the camera,
Understanding the basics of exposure will take
your photography skills to the next level
.

The moment of exposure:
Most of the time, the inside of the camera is totally dark. When a photograph is taken, the camera opens and light from outside floods in through the lens. Light is projected onto film to make the exposure.

Whether you use traditional or digital film, the concepts the same..

Exposure is the measuring and balancing of light

Too much light and the picture will be washed out. Not enough light and the picture will be too dark. A good photograph depends on calculating the exposure settings that will give the film the "right" amount of exposure.

The photographer can control how much natural light reaches film
by adjusting the camera's shutter, aperture, or film speed.

Measuring light (technical exposure)
A good technical exposure will produce a final image that accurately represents the original scene.. Film is light sensitive, and if the exposure is too dark or too bright, the result will not look like "real life".

Balancing light (artistic exposure)
Just to make things interesting, in any situtation there are several camera setting that give exactly the brightness but with very different outcomes. Which to choose is up to you, the photographer.
