 * SLR WORKSHEET**

Depth of field... Depth of range is the range of distance within the subject which is sharpest. It is affected by aperature and focusing distance. The depth of field isn’t an abrupt change, but more gradual.

Shutter Speed...  Shutter speed is the amount of time that the shutter is open, and how long the image sensor for a digital camera sees the image it is being exposed to. The longer it is exposed, the more movement will be caught, and the more blur there will be.

Noise... Noise in photography is the random variation of brightness or color in the image. Generally disrupts clarity and is undesired.

Histogram... A histogram is a graph that shows how many pixels are between black and white. Color histograms do the same with color. These often help determine when something is underexposed or overexposed, or can read white balance.



Burst mode... Also known as continuous shooting mode. It's useful for taking photos of moving objects, and single shots can be chosen out of many. However, you usually need to focus the camera beforehand.

White balance... White balance is the process of readjusting colors cast in a picture to the whites seen in by the viewer in real life. The camera adjusts itself to the background's color temperatures to judge the correct, realistic white balance.

Self timer... Timers are usually used to take self portraits or to take group shots. Self timers create a delay between the time of the shutter release and the shutter firing.

Pixels... A pixel is a single point in a raster image. It is the smallest unit of a screen on which a picture can be controlled

Auto vs Manual focus... Cameras have both automatic and manual shooting modes. In auto mode, the camera makes the decisions. However, manual focusing is helpful in certain situations. Macros, photographs taken in low lighting, action shots, portraits and objects shot through glass or wire often benefit when one controls the focus themselves. Sometimes in auto focus, the camera won't know what to fcous on.

ISO... Also known as International Standardization Organization. An ISO image is an archive file of an optical disc that is in a format defined by the ISO.

File format... .tiff - .jpeg - .raw -
