TIFF

A format for saving image data in a non-compressed format. Image data using this format has a large file size and is not suited for attaching to e- mail, but is suited for processing on your PC.

Color Temperature

This numerically expresses the color of the light source illuminating the subject. This is indicated in absolute temperature, using Kelvin (K) units. The color of light shifts to a bluish color as the color temperature rises, and to a reddish color as the color temperature falls.

Color space

A system that organizes colors. Colors displayed on displays for PCs and televisions are rendered with combinations of RGB (red, green, blue), and those for color printed materials, such as pamphlets, are rendered with combinations of CMYK (cyan, magenta, yellow, black). Color space is the method in which specific colors are rendered through a certain method.

Quality Level

This refers to the image compression ratio. The lower the compression, the more detailed the image. The image becomes rougher as the compression rate rises.

Recorded Pixels

Indicates the size of the image by the number of pixels. The more pixels that compose a picture, the larger the image size.

Histogram

Graphed presentation of a gradation sequence that shows the darkest point in an image to the brightest. The horizontal axis represents the brightness and the vertical axis represents the number of pixels. This is useful when you wish to refer to the exposure status of an image.
