EXIF is a way of storing supplementary data in a media file. EXIF data can be stored in JPG, TIFF and RIFF WAV. I'd guess that scanner is generating TIFF files. That is a common scanner output format which supports: "lossless" compression, EXIF, multi-page images, and transparency. To check the file type for TIFF, the first two bytes will be "ll" or "MM" (depending on "endian-ness" and the next two bytes will bebig/little endian "42". -- Stuart On 30 Aug 2011 at 16:13, Gary Kjos wrote: > Mine all have "Exif" not JFIF Checked images from 3 different > cameras. > > GK > > On Tue, Aug 30, 2011 at 3:42 PM, Steve Goodhall <steve at goodhall.info> > wrote: > Open the file in a text editor such as Notepad++.
