Activity 2.2: Camera Basics (Reposted)

Image Size/Quality
The size of the digital file corresponding to the image that the camera produces depends on the pixel count. These files can be pretty big but can be compressed without a major drop in quality. They can be converted into a JPEG file.

Picture Modes & Custom Colour Modes
There are many different picture modes used for taking certain types of pictures. For example, there is: portrait mode, macro mode, landscape mode, sports mode, and more. These modes are specialized for certain situations. There are also many different custom colour modes. These are used for certain light situations in the location where the photographer is shooting. For example, there is: auto, tungsten, fluorescent, daylight, cloudy, and more.

Burst Shooting and Timer Shooting
Burst shooting is when the camera is set to take several pictures at once (taking one after another). Timer shooting is when the camera takes a photo automatically when set to a specific time limit.

Metering Modes
In metering mode, the camera attempts to take in consideration everything in the frame. It assesses the overall lighting and averages it to determine how to expose the shot.

AF Modes
AF stands for autofocus. It is an optical system that uses a sensor, control system, and a motor to focus fully automatic or on a manually selected point or area.

Histograms
A histogram is a small graph shown on a camera. It graphs the tonal range on the image taken (from left-black to right-white). The higher the graph in these areas, the more pixels of that tone are present.
