Activity 2.4: Camera Accessories (Reposted)
A tripod is a portable three-legged frame used for supporting the weight and keeping the camera stable. It reduces camera shake and allows for a slow shutter speed without any blurs. A monopod is like a tripod except with only one leg.
A flash a camera device used to produce an artificial flash of light. Its main purpose is to illuminate a dark scene. It can be used to capture quickly moving objects or changing the quality of light.
A strobe light is a device used to produce regular flashes of light. Larger strobe lights can be used in a continuous mode where they produce extremely intense illumination.
Most photographers without studios use continuous lights that usually have three parts - stands, reflectors, and bulbs.
A soft box creates soft light. It directs light through a diffusing material or "bounces" light off a second surface to diffuse the light.
Umbrellas with a reflective insides are used as a diffusion device when using artificial lighting. It is also used as a glare shield and shade in most portrait situations.
Barn doors are an accessory used on spotlights and flood lamps. They help control the direction of light and the width of the beam.
Colour gels are a transparent coloured material that are used to colour light and for colour correction.
Gobos are used to film sets. It is a physical template slotted inside or placed in front of a light source to control the shape of emitted light.
A reflector is used as an improvised or specialized reflective surface to redirect light towards a given subject or scene. For example, reflecting sunlight.
A light meter is a device used to determine the proper exposure for a photo. It helps the photographer determine which shutter speed or f-stop should be selected for the best exposure.
A card reader is a data input device that reads data from card-shaped storage mediums. For example, an SD card.

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.
