BASICS OF PHOTOGRAPHY
Aperture: F-Stop controls the amount of light that is let through the lens of the camera. The smaller the f-stop the more light it lets through the lens when taking a picture. They are measured in f-Stops: f2.8, f4, f5.6, f8, f11, f16, f22

Exposure: A combination of how much light is let through the lens and how fast the camera takes the picture. These combined results in how much light is let through the camera’s lens.
Underexposure: There is not enough light entering the camera nor for a long enough time, often making the picture looks rather dark.
Overexposure: There is too much light entering the camera for too much time often making the picture look very bright.
Equivalent Exposure: The combination of the amount of light let through the lens and how long the light is let in for that allows equal amount of light to enter the camera.
Pixel: The unit of image displayed on a computer or television or electronic device. Pixels are generally arranged in rows and columns; the pixels vary in brightness and color values.
Megapixel: One mega pixel is equal to one million pixels and is shaped into a rectangle.
Resolution: It is the number of pixels that are put together to form an image. Pixel’s are boxes of color that form images. The higher the resolution, the more boxes and the more crisp the image.http://kesslercreative.com/glossary.php

Shutter: It is the time that the shutter opens and it controls the amount of light that that passes through. It is measured of fractions of seconds. The smaller the fraction, the less light is let through and it is normally a crisper image. The larger the fraction the more light it lets through for a longer time and often makes the moving objects in the photo blurry.

Depth of Field: Distance between the nearest and farthest objects that appear in acceptably sharp focus in a photograph. The two main types of depth of field are shallow and extended. Shallow depth of field is when the only the main subject of interest is in focus (normally the closest) and everything else behind it is blurry (the background). Extended depth of field is when the background is sharp and clear and the foreground is blurry.

Another example of depth of field is when the foreground and background are blurred and the mid-ground is in focus.
