Title:
  enblend 4.1 generates brighter images than originals

Status in Enblend:
  Incomplete

Bug description:
  I just notice that the recent versions of enblend (4.1 I think) generates a panorama image which is much more brighter than the original JPEGs.
  When the original JPEGs contain some black or dark areas, they becomes grey (like a problem of gamma).
  I check with Gimp and the histogram no longer contains black or dark colors as if it was compressed at right.

  As I didn't remember this kind of problems with previous enblend versions, I looked in recent options like CIECAM02 which is enabled by default.
  And, when I use --no-ciecam, the problem disappears.

  (In my case, all my original JPEGs are in sRGB and for this test case,
  I haven't done any exposition correction in Hugin : I just compare the
  result by adding and removing --no-ciecam).

  So, is it a regression or an expected behaviour ?
