+
+\image Effects-HDRBloomTonemap.png
+
+The \"HDRBloomTonemap\" effect provides two features:
+
+\list 1
+\li
+  Adjust the gamma and exposure of the high-dynamic range rendered
+  content to achieve the image quality you want, and
+\li
+  Apply an adjustable 'bloom' effect to very bright areas (like the sun
+  glinting off a car).
+\endlist
+When you add an HDRBloomTonemap effect to a layer, the following
+properties are available in the Inspector palette:
+
+\list
+\li
+  \b{Gamma} - this affects the non-linear curve of the lighting.
+  Higher values will increase the exposure of mid tones, lightening the
+  image (and decreasing the contrast). A value of \c{1.0} causes no
+  adjustment to the image.
+\li
+  \b{Exposure} - this is a linear multiplier on the lighting,
+  brightening or darkening the image overall. A value of \c{0.0}
+  causes no adjustment to the image.
+\li
+  \b{Bloom Threshold} - lighting greater than this value will
+  bloom. A value of \c{1.0} corresponds to white in the original
+  render result. Lowering this value will cause more areas of the
+  rendered scene to bloom; at a value of \c{0.0} everything in the
+  scene will bloom.
+\list
+\li
+  \e{Tip: to disable bloom and use only the tone mapping, set this to
+  a sufficiently high value, like \c{999}.}
+\endlist
+\li
+  \b{Bloom Falloff} - adjusts the amount of bloom. Lower values
+  result in stronger bloom effect; higher values make the effect more
+  subtle.
