Camera Settings and "Lingo"

There are several terms which I would like to define.

Exposure: Simply defined exposure is the "brightness" of the photo.  This is changed by the Shutter Speed, Aperture, and ISO.

-Shutter Speed: The time a camera's light sensor is exposed to light.  This changes the exposure of the photo.  This is measured in seconds. i.e. 1/250, 25 15.  The faster the shutter speed the darker or less exposed the photo will be.

-Aperture: The size of the opening in a camera's lens, measured in "f stops." i.e. 3.5, 8, 29  The larger the "f stop" the smaller the opening.  This also determines the exposure. (Aperture is also a photo editing/cataloging software, produced by Apple Computer) 

- ISO: The camera's sensitivity to light. The higher the ISO number the higher the exposure will be.  As the ISO number is increased the photos may become grainy.

White Balance: Simply defined white balance is how the camera sees the color white.  Changing this will change the tint of the picture.

In the next few posts I will show you how these different settings effect the photos.
