 ====== 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).
-Currently only one algorithm is implemented which uses an Exposure and Contrast setting.
+===== 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.
