13 This command implements a tone mapping operator as described in:
14
15 Time-Dependent Visual Adaptation for Realistic Image Display. S.N.
16 Pattanaik, J. Tumblin, H. Yee, and D.P. Greenberg. In Proceedings of
17 ACM SIGGRAPH 2000.
18
19 This operator requires properly calibrated image data (in cd/m2) and
20 its results should be gamma corrected.
21
22 The local version of this operator is based on the following paper:
23
24 Adaptive Gain Control For High Dynamic Range Image Display. S.N. Pat‐
25 tanaik, H. Yee. In proceedings of SCCG 2002.

29 --time-dependence, -t
30
31 Use time dependent model of adaptation. This should be used for
32 tone mapping of an animation. It has no influence on single-
33 frame input. Switched off by default. Note: it is important to
34 correctly set the speed of the input animation (--fps).
35
36 --fps <val>, -f <val>
37
38 Speed of input animation in frames per second. Used when time-
39 dependence is switched on (-t). Default value: 16.0
40
41 --mul <multiplier>, -m <multiplier>
42
43 Multiply input values by a multiplier value. Useful if input
44 data is not calibrated. Default value: 1.0
45
46 --local, -l
47
48 Use local version of the tone mapping. Time-dependent effects
49 are cancelled while using local version, global version is used
50 by default.
51
52 --cone <val>, -c <val>
53
54 Set the adaptation level for cones. If --rod parameter is not
55 used, this will also set the adaptation level for rods. By
56 default, the adaptation level is calculated as a logarithmic
57 average of luminance in the input image.
58
59 --rod <val>, -r <val>
60
61 Set the adaptation level for rods. By default, the adaptation
62 level is calculated as a logarithmic average of luminance in the
63 input image.
64
65 --verbose
66
67 Print additional information during program execution.

69 --help
