>That's not exactly correct. Is anything, ever? :o) <If you have a lot of work to do on an image and the output is going to be 8 bit you are still better off to work on it in a higher bit depth, when you take it back down to 8 bits you will not loose nearly as much information on the image as if you had worked on it in 8 bit to begin with.> For many images the differences may well be small. I'm more interested in the other benefits such as - increasing exposure latitude. Beyond 16-bits is more the domain of computer graphics. Most real lenses have far too much flare to do justice to the dynamic range encodable within HDR ! >Still not convinced about DNG! Well, it might not be perfect but it must be better than the 500+ different "raw" formats around at the moment - most of which are undocumented! -- Whatever you Wanadoo: http://www.wanadoo.co.uk/time/ This email has been checked for most known viruses - find out more at: http://www.wanadoo.co.uk/help/id/7098.htm
