E. Reinhard, M. Stark, P. Shirley, and J. Ferwerda. In ACM Transactions on Graphics, 2002. <P> According to the paper, results of this TMO require gamma correction. <H3>OPTIONS</H3> <DL COMPACT> <DT><B>Key Value</B><DD> <P> Set key value for the image (refer to paper for details). Default value: 0.18, accepted range <0..1>. <DT><B>Phi Value</B><DD> <P> Set phi value (refer to paper for details). Default value: 1.0, accepted range >=0.0. <DT><B>Use Scales</B><DD> <P> Use scales to calculate local adaptation. That means: use local version of this operator. By default, global version is used. <DT><B>Range</B><DD> <P> Set range size (refer to paper for details).
