Title:
  EV value 8 steps off with a "linear" camera

Status in Hugin - Panorama Tools GUI:
  Expired

Bug description:
  (This was with May 2008 "CVS-like" version.)

  When I switch the "camera sensor model" (or whatever it is called) to
  "linear" in the exposure-related tab, then optimize the exposure, and
  go to the preview window, I can (as usual) tune the EV compensation
  value.  However, the value which makes the preview window "good" is
  about 8-9 steps off the value which is "good" for the finally created
  image (e.g., one requires EV9.67, and another EV1).

  Observed on Windows; maybe it is related to a "wrong byteorder"
  somewhere in the pipeline?
