Difference between EXR and TIFF

Steps causing the bug to occur

  1. Run supplied composition
  2. Exported TIFF and EXR have different colours
  3. When viewed in an EXR viewer (Natron) red is still present at bottom left corner (0,0) of UV map

If you view the images side-by-side in Vuo, they look identical.

It looks like the difference arises in Natron. It appears to be tonemapping the EXR file and not the TIFF file. (Vuo doesn’t automatically do tonemapping.)

Thanks for taking the time to look into this @jstrecker!
