It's hard to see how you can losslessly compress some images to 50% unless the source "information" is hollow to start with. Of course: raw is not raw. Nikon's NEF format has less bits per sensor than the camera does for intance (it's already been processed). The real problem with proprietry raw formats is that they are undocumented, not that one is better than another. At least with TIFFs anyone can read them ... and the private tags too if you have a mind to look inside. Bob
