Well, in remote sensing it was mostly 8-bit data per frequency range, then each satellite or instrument by name (LANDSAT, GOES, SPOT, etc.) has its own file format. Sometimes a CCD bit was stuck, so we would process around that, etc. The terms "HDR" and "photo" are not commonly used. The Perkin-Elmer military system has fortran source, so all the file formats are documented there (if you can get access), as well as a minimal Scottish university system.
