This plugin dynamically applies an autolevels effect to the krpano view. When properly used, this can mimic autoexposure of a (video-)camera, or the adaptation of the human perceptive system. The effect can be tuned to affect just the luminosity of the view, or the luminosity as well as the color of the view.
Please note that the effect is applied to the (jpeg compressed) 8 bit panorama, so if the effect is too pronounced you will start to see artifacts such as banding and color mismatches.
The autolevels sources and examples are available as part of the fovplugins package
