Retinex Models
Land’s Ives Medal Address
In 1968, Land demonstrated the first electronic (analog) HDR rendering in his Ives Medal Address to the OSA. Here the intent was to render HDR images using spatial comparisons. I described the first ratio-product-reset model for calculating the appearance lightness.

In 1978 Frankle and McCann patented a very efficient digital spatial-comparison HDR algorithm.
In 1999 McCann wrote a review of different Retinex algorithms.

In 2004 McCann wrote a review of the history of Retinex algorithms.
