That is interesting! I can't see how I let alone any law enforcement agency would trust that if the method is secret - the only reliable way of doing that would be embedding a cryptographically secure digital signature to the file, and there's no way to verify its security without knowing the algorithm used. I haven't found anything suitable-looking in 10D's RAW files but there's stuff in there whose significance I don't know, and of course it's possible the 1Ds puts something more in there. It might be an interesting project to figure out... -- Tapani Tarvainen * **** ******* *********************************************************** * For list instructions, including unsubscribe, see: * http://www.a1.nl/phomepag/markerink/eos_list.htm ***********************************************************
