Talbot-Plateau law

The Talbot-Plateau law is an experimental observation related to the psychophysics of vision.

[2] The law was first reported in a 1830 article by the Belgian scientist Joseph Plateau.

[3] This article stimulated the English photography pioneer Henry Fox Talbot to publish, in 1834, his own observations on this topic made back in the 1820s.

[5] In 1863, the experiments of A. Fick suggested that the Talbot-Plateau law does not hold for strong light intensities.

This suggestion was later proven by O. Grünbaum in 1898 who demonstrated that flickering strong light appears brighter than its steady state value.
