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.
