True, however the full precision of the calculation can be seen in the 16 output bits, they aren't just 16bits padded to 12bits. This is an important point and can be likened to oversampling in that it leads to a greater number of transitions colour to colour etc. Rob Studdert HURSTVILLE AUSTRALIA Tel +61-2-9554-4110 UTC(GMT) +10 Hours [EMAIL PROTECTED] http://members.ozemail.com.au/~distudio/publications/ Pentax user since 1986, PDMLer since 1998
