I scanned a photograph using vuescan pro. and a Epson 3490 Perfection scanner. I set vuescan to output a raw compatible file with DNG extension.
The file created had a physical size on the hard drive of 144 Mega-bytes. When opened in camera-RAW 7.3 and simply saved without compression it became 74 Mega-bytes. I open both files in photoshop cs6 and they both read exactly the same in all respects including size on disk i.e. Doc:144/144 all dimensions and resolution are the same. Is file compression taking place silently without my knowledge when I saved from Camera RAW?
If the file's contents expand to the same, then is it possible to get vuescan to save the files in the smaller size?
