Color Depth & Quality
http://en.wikipedia.org/wiki/Color_depth 1 bit 8 bits 4 bits 24 bits
(true color) Space considerations
Space considerations Quality depends on: resolution color depth (how many bits per pixel) Space required depends on:
resolution, color depth. Bits Needed = num pixels x bits/pixel e.g. 600x600, truecolor > 6002 x 24
= 8,640,000 bits
= 1,080,000 bytes (8 bits to a byte)
= 1.08 Mb file (.bmp) More on Resolutions….

– resolutions greater than 300dpi refer to individual color dots used to make up a single pixel. http://www.earthboundlight.com/phototips/digitalvers
– “grain size” for film comparable to resolution on high
end digital camera (about 5 microns). http://www.hdtvinfoport.com/HDTVResolution.html
– sdtv versus hdtv (various versions) Compression
