No disrespect and I probably don't know anymore than you do, but let's make that guess a bit more informed. If you look at the link below, you will find that the RAW does not have all the processing you mentioned applied. If it was, then the camera could simply output a TIFF (lossless) file. And that would also be why a JPG thumbnail is saved alongwith so that the file can be quickly previewed without waiting to apply the (lengthy) process of intepolation etc. to get the actual color pixels to render the image for view/preview. Also the author specifically mentions that the RAW is *not* a TIFF type file - only the header is similar to TIFF. http://www.cybercom.net/~dcoffin/dcraw/secrets.html - Harman __________________________________ Do you Yahoo!?
