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] [--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]

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

       [--key <val>]

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

       [--phi <val>]

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

       [--range <val>]

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

       [--lower <val>]

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

       [--upper <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.

       --verbose

              Print additional information during program execution.

       --help

              Print list of commandline options.

EXAMPLES

       pfsin memorial.hdr | pfstmo_reinhard02 -s | pfsgamma -g 2.2 | pfsout memorial.png

              Tone map image and save it in png format.
