Hello, I would like to talk about photography. Photography is the art, application and practice of creating durable images by recording light or other electromagnetic radiation; either electronically by means of an image sensor, or chemically by means of a light-sensitive material such as photographic film.
Historically speaking, l photography used to be monochrome, or black-and-white. Even after colour-film was readily available, black-and-white photography continued to dominate for decades, due to its lower cost, chemical stability, and its “classic” photographic look.
Colour photography was explored in the beginning of the 1840s. Early experiments in colour required extremely long exposures (hours or days for camera images) and couldn’t “fix” the photograph to prevent the colour from quickly fading when exposed to white light.
