Karl You sound very confused I'm afraid :o( A single bit can capture an (almost) infinite dynamic range But with no gradation of tones As long as you know what on and off refer to. 8 bits can hold 256 levels of tone - and those tones can be whatever you want them to be. They don't have to be a simple gamma curve. Bob ___________________________________________________________ Tiscali Broadband from 14.99 with free setup! http://www.tiscali.co.uk/products/broadband/
