Explanation of Terms
EV
A number denotes Exposure Value. The EV is determined by the brightness of the subject and sensitivity (speed) of the film
or CCD. The number is larger for bright subjects and smaller for dark subjects. As the brightness of the subject changes, a
digital camera maintains the amount of light hitting the CCD at a constant level by adjusting the aperture and shutter speed.
When the amount of light striking the CCD doubles, the EV increases by 1. Likewise, when the light is halved, the EV decreases
by 1.
JPEG
Joint Photographic Experts Group
A file format used for compressing and saving color images. The higher the compression rate, the greater the loss of quality in
the decompressed (restored) image.
Smear
A phenomenon specific to CCDs whereby white streaks appear on the image when there is a very strong light source, such as
the sun or reflected sunlight, in the photography screen.
White Balance
Whatever the kind of the light, the human eye adapts to it so that a white object still looks white. On the other hand, devices
such as digital cameras see a white subject as white by first adjusting the color balance to suit the color of the ambient light
around the subject. This adjustment is called matching the white balance.
CCD-RAW
This is the image data prior to signal processing (the reconstruction of the data read in from the CCD as an image). Because
the signal processing is performed on the computer, high levels of control are possible.

Color Temperature
A low-temperature light source, such as a candle flame, is strongly red, while a high-temperature light source, such as a gas
burner flame, is strongly blue. The color of the light for these temperatures is expressed as a color temperature (K = Kelvin).
The light of the sun at midday in a completely clear sky is taken to be 5500K.
