Graphs tones from left to right, black to white. Tells how many pixels are in each tone.
The graphs can be really high (bright) or really low (dark)


Burst Mode

A setting that the camera has that lets you take multiple images continuously.
Works better on fast moving objects.

White Balance

Wrong White Balance
Right White Balance

Removes unrealistic color casts. Can turn the photo slightly blue. Depends on lighting conditions.

Self timer:
Used on digital cameras when you want to take a group photo or a self portrait. A camera can be placed onto a tripod for a clearer photograph.



Also known as picture elements. millions of pixels combine to create a detailed image.

Auto Focus vs Manual Focus: (explain what they are and then explain when you would choose each and why?) With AF it can not take wide open close focusing shots as well as MF.
Manual Focus should be used when doing Macro photography. You need to be incredibly precise with focusing and being just a smidgeon out or having your camera choose to focus on the wrong part of your subject which can completely ruin your shot.
Auto Focus works by using a contrast sensor that is found within the camera or by sending a signal to illuminate or estimate distance from the subject.

Depth of field:

Depth of field is the range of distance within the subject that is acceptably sharp. The depth of field varies depending on camera type, aperture and focusing distance, although print size and viewing distance can influence our perception of it.

Shutter Speed: is the length of time that your image sensor ’sees’ the scene you’re attempting to capture. The shutter speed is measured in seconds or fractions of seconds.
You can freeze an image by choosing a faster shutter speed, and show movement by using a slower speed.

Noise: is a problem in digital camera sensors and in most parts of analogue (electronic) cameras. Noise most commonly appears as either random colored dots sprinkled around the image, or uneven coloration of what should be smoothly-colored areas.

Aperture: The size of the opening in the lens also known as f/stop. (a smaller aperture has a bigger f/stop number--lets in less light) The numbers represent ratios of the lens focal length to opening. The lens focal length is how long the lense is in millimeters. So f/2 is a wider open aperature than f/16 because the numbers are fractions.
