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.
