Kodak is an integral part of PIMA and the TIFF/EP spec (http://www.pima.net/standards/iso/tc42/documents/N4378.pdf) which they themselves have implemented in their DCS 5xx/6xx cameras. It would be pretty scary if some group in Kodak is still using TIFF/OJPEG when most of the company has gone out of its way to avoid it. If you're talking about what used to be the Wang Imaging crapplication, then this is a different story. -- Kenneth Murchison Oceana Matrix Ltd.
