-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.

- \e{Tip: to disable bloom and use only the tone mapping, set this to
