color depth
How many colors are there is a 1-, 2-, 4-, 8-, 24-, and 32-bit graphics? The following table illustrates the color availability of each bit-depth:
Bit Depth Colors Available
1-bit Black and White
4-bit 16 colors
8-bit 256 colors
16-bit Thousands of colors
24-bit Millions of colors
32-bit Millions of colors+*
The bit depth of an image makes up the color value assigned to each pixel in the image. For instance, a 1-bit image assigns each pixel a black or a white value, a 4-bit image assigns each pixel one of the 16 color values, and so on*. The only exception is that a 32-bit image is usually a 24-bit image with additional information encoded in the remaining 8 bits.

in order to preserve as much information as possible when we apply color corrections, filters and other algorithms that affect the dynamic range of the image. we hope that what is left will be well resolved and capable of going out to film.
