====== Tonemapper ======
{{ :tools:tonemapper.png?nolink|}}
This pixel filter applies simple tone mapping to the image, as it renders. It can be edited interactively while VPR renders (but causes VPR to re-render when any of the settings change).


===== Mode =====
Currently three simple algorithms are implemented:
==== Simple ====

Just flattens the image, making sure that there's no values above 1.0.

==== Gamma Compression ====

Exposure multiplies the colour, Contrast is a gamma value.

==== Chaos ====

The same as Gamma Compression but Contrast is identical to the one used by VRay, which tries to preserve more details in dark and bright areas.

===== Enabled =====

Toggles if the pixel filter is being used (useful when used with VPR to check the effect)

===== Affect Final Render =====

If enabled, the Exposure will affect final renders as well (F9/F10). Usually this is off, assuming that a more sophisticated algorithm will be used in post.
