Basics of Digital Photo
Pixel: The smallest unit of a digital image that can be represented or controlled.
Megapixel: One million pixels gridded into a pattern in the shape of a rectangle.
Resolution: The number of pixels that make up an image. Pixels are like tiny boxes of color that when you put them together, form a picture.

Aperture: Diaphramatic opening in lens that controls how much light is let through the lens when taking a picture.
Shutter: It is how long the lens opens and it also determines how much light is let through. These are measured in fractions of seconds.

Exposure: A combination of how much light is let through and how long the light is let through for that determines the lighting of the picture.
Overposure: It is when there is too much light entering the camera, making the picture extremely bright.
Overposure: It is when there is too much light entering the camera, making the picture extremely bright.
Underexposure: There us too little light entering the camera, making the picture seem very dark.
Equivalent Exposure: The amount of light let through the lens and how much light the lens let through which makes the picture have perfect lighting.
Depth of Field: The distance between the nearest and farthest objects in a scene that appear sharp.
