pfstmo_reinhard02(1)	     General Commands Manual	    pfstmo_reinhard02(1)

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 ver-
	    sion 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, ac-
	    cepted range >=0.0.

     [--range <val>]

	    Set range size (refer to paper for details).  Default value: 8,  ac-
	    cepted 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 consec-
	    utive 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 memor-
     ial.png

	    Tone map image and save it in png format.

     Please  report  bugs  and	comments  on implementation to Grzegorz Krawczyk
