Does photosynthesis have anything to do with photography?

Answer 1

Photosynthesis and conventional (chemical) Photography are distantly related insofar as both use photochemistry, which is any process by which exposure to light causes a chemical change in a substance.

In a plant performing photosynthesis, the light reaction causes a chemical change in the presence of chlorophyll by which the plant converts light energy into sugar energy using water and carbon dioxide.

In chemical photography the light reaction converts light energy chemically into a latent (hidden) image in a light sensitive material such as a salt (halide) of silver. The latent image can then be further chemically developed into a visible image.
