[QUOTE="aroy, post: 490724, member: 16090"] 12 bits has the last 4 bits ;of a 16 bit number; zero. Similarly 14 bits have the last 2 bits as zero. The reason to have 16 bit data is that all memory is BYTE aligned and 16 bits is the next nearest to 12 and 14 bit data. Proprietory format like NEF use lesser bits to save storage space and increase throughput speed, but computers rarely use odd bit data. As it is every time normal software has to use data that is not multiple of a byte, it has to translate/format it to byte aligned data. The number of significant bits depends on the accuracy of the A-D converter, and some MF designs have true 16 bit data, but most do not. With higher number of bits you get more shades of colour, hence the transitions are smoother. 12 bits = 4096 shades 14 bits = 16384 shades 16 bits = 65536 shades Whether you can utilise the minor colour variation depend on your output device. The eye can, but most monitors and printers cannot. [/QUOTE]
