Features Of An Ideal Image Editors
It is possible, using software, to change the color depth of images. Common color depths
are 2, 4, 16, 256, 65,536 and 16.7 million colors. The JPEG and PNG image
formats are capable of storing 16.7 million colors (equal to 256 luminance values
per color channel). In addition, grayscale images
of 8 bits or less can be created,
usually via conversion and down-sampling from
a full-color image. Grayscale conversion is
useful for reducing file size dramatically when the original photographic print
was monochrome, but a color tint has been introduced due to aging effects.
