 Getting More out Of Your Camera







 Exposure

Exposure is the anount of light which is collected by the sensor in your camera in a single picture.
If a shot is exposed for too long then it looks washed out. (Example to the left)
 This is the same picture but with no expure, this picture is not affected and really doen't need exposure.

 This is a picture that has exposure on low and it makes the picture really dark and unappealing to viewers
 Flash
A flash is a device used in photography producing a flash.
The picture to your right is a poor use of flash as the reflective surface is highlighting the light. Flash should only be used in dark atmospheres and if the subject is close.
 With no flash on the reflective object it only shows what is front of the object.
In the pictures taken the flash affect was used to show the difference between flash and no flash. In the picture to your right we see the object with digital light being shown as it reflect of her eyes more than the picture below.
In the picture to your left we the same object with no flash which help proove that flash wasn't needed in this image.
White Balance
"White balance (WB) is the process of removing unrealistic color casts, so that objects which appear white in person are rendered white in your photo.
(AWB) — and can create unsightly blue, orange, or even green color casts. Understanding digital white balance can help you avoid these color casts, thereby improving your photos under a wider range of lighting conditions."
This function did not damage my work but it made my pictures very decieving, it was hard for viewrs to guess the time period due to the lighting

Colour Mode
Allows a photographer to be able to make the picture warmer,cooler, sepia, black and white just by changing the tint.
My pictures were not damaged by this color mode but it was seen as unsightly to other views eyes.
In the picture taken (right hand side) displays a playground with the colour effect, the affect makes it hard for the viewer to acknowledge what type of weather is being shown.



Auto Focus
Auto focus relates to which part of the subject you want your camera to focus on.
Autofocus systems rely on one or more sensors in the camera to determine correct focus. Some AF in other cameras systems rely on a single sensor, while others use an array of sensors.
In more expensive cameras like SLR Cameras they use through-the-lens optical AF sensors, with a separate sensor array providing light metering.
Through-the-lens optical autofocusing is now often faster and more precise than can be achieved manually with an ordinary viewfinder which is in cheaper cameras.
Some AF cameras are able to detect whether the subject is moving towards or away from the camera, including speed and acceleration data, and keep focus on the subject. A function used mainly in sports and other action photography. On Canon cameras this is known as AI servo, while on Nikon cameras it is known as "continuous focus".
Burst
Burst is a shooting mode in still cameras, most of the digital cameras have single-lens reflex which allow several photographs to be captured in quick succession by either single pressing the shutter button or holding it down.
This is used mainly in mixed-light conditions or when the subject is in successive motion, such as sports.
successive photographs can be captured depends on a variety of factors, mainly the processing power of the camera. Disabling certain features such as post processing which the camera applies automatically after capturing each image will usually allow a faster rate of capture.
While some cheaper point and shoot cameras may have a multi-image burst function which allows them to capture a certain amount of frames within a second with a single shutter button press
More expensive cameras like SLR cameras will will continue to actuate the shutter for as long as the button is held down, until the memory card is full or the battery runs out
The picture i have  taken have not been damaged and help iilustrate the technique to the fullest using the burst mode.
