Q. Show the Dynamic Range and Colour Depth?

Dynamic Range is the number of colours a colour scan or number of grays a monochrome scanner can distinguish. The dynamic range is typically given as bit-depth or colour depth.  This is merely the number of bits to distinguish the colours. Most scanners can do 256(8-bit), 1024(10-bit) or 4096(12-bit) for every primary colour. This adds up to and is advertised as 24-bit, 30-bit and 36-bit colour scanners. Essentiallyhowever to utilise Colour Depth, the image under scanning should be properly focused upon and properly illuminated by scanner. 

Subsequently the minimum colour range useful for human vision is 24-bits more bits can seem useful.  Thoughextra bits of scanning give you firm control for filtering image colour to your needs.
