Question

During an 1861 lecture at the Royal Institute,
used his three- color analysis in his first demonstration of
photography.

Answer 1

In 1861, the scientist **James Clerk Maxwell** presented his work on the first color photograph during a lecture at the Royal Institution. He demonstrated the principle of color photography using a three-color analysis, where he took three separate photographs of the same scene through red, green, and blue filters. When these photographs were projected together with the corresponding filters, they produced a full-color image. This groundbreaking work laid the foundation for the development of color photography.
