NAME
       pfstmo_reinhard02 - Photographic Tone Reproduction for Digital Images

SYNOPSIS
       pfstmo_reinhard02 [--scales] [--key <val>] [--phi <val>] [--range
       <val>] [--lower <val>] [--upper <val>] [--temporal-coherent] [--border
       <val>] [--verbose] [--help]

DESCRIPTION
       This command implements a tone mapping operator as described in:

       Photographic Tone Reproduction for Digital Images.  E. Reinhard, M.
       Stark, P. Shirley, and J. Ferwerda.  In ACM Transactions on Graphics,
       2002.

       According to the paper, results of this TMO require gamma correction.

OPTIONS
       [--scales] [-s]

              Use scales to calculate local adaptation. That means: use local
              version of this operator. By default, global version is used.

       [--key <val>] [-k <val>]

              Set key value for the image (refer to paper for details).
              Default value: 0.18, accepted range <0..1>.

       [--phi <val>] [-p <val>]

              Set phi value (refer to paper for details).  Default value: 1.0,
              accepted range >=0.0.

       [--range <val>] [-r <val>]

              Set range size (refer to paper for details).  Default value: 8,
              accepted range >1.

       [--lower <val>] [-l <val>]

              Set lower scale size (refer to paper for details).  Default
              value: 1, accepted range >=1.

       [--upper <val>] [-u <val>]

              Set upper scale size (refer to paper for details).  Default
              value: 43, accepted range >=1.

       [--temporal-coherent], [-t]

              When this option is specified, tone mapping is time coherent for
              video sequences. Currently the option imposes that the average
              and maximum luminance value can change at most by 1% between two
              consecutive frames.

       [--border <val>] [-b <val>]

              Use border mechanism with specified relative border width.
              Actual border size will be calculated as the minimal size of the
              image (width or height) multiplied on relative border width.
              Default value: 0 (don't use border mechanism), accepted range: 0
              >= b < 0.5.

       --verbose

              Print additional information during program execution.

       --help

              Print list of commandline options.

EXAMPLES
       pfsin memorial.hdr | pfstmo_reinhard02 -s | pfsout memorial.png

              Tone map image and save it in png format.
