NOTE ON EXPANSION OPERATORS (INVERSE/REVERSE TONE MAPPING):
The majority of EOs require to have as input LDR/SDR images that are NORMALZIED (i.e., in the range [0,1])
and LINEARIZED. To be LINEARIZED means that the camera response function (CRF) or the gamma encoding has been removed.
This operation is MANDATORY in order to generate FAIR comparisons.
NOTE1: Please DO use the gammaRemoval parameter to remove gamma encoding if you do not have the CRF of the input image. Note
that this is an approximation.
NOTE2: RAW files do not require this step because they are already linear. Therefore, for ONLY these
images set gammaRemoval = 1.0.
NOTE ON TONE MAPPING:
The majority of TMOs return tone mapped images with linear values (i.e., withouth a CRF or gamma encoding).
This means that gamma encoding needs to be applied to the output of these TMOs before visualization or before
writing tone mapped images on the disk; otherwise these images will appear dark.
A few operators (e.g., Mertens et al.'s operator) return gamma encoded values,
so there is no need to apply gamma to them; in this case a message (e.g., a Warning) is displayed
after tone mapping alerting that there is no need of gamma encoding.
