The first permanent image was captured by Frenchman Nicéphore Niépce, of the view outside his window, in 1827. Niepce’s partner Louis Daguerre. He refined the method so that it took minutes instead of hours, and this allowed him to capture the first image of a human. He called his product a “Daguerreotype,” and made his research public. Once Englishman Henry Fox Talbot heard of Daguerre’s process, he published his own discoveries, which included a transparent negative from which many prints could be made.
Over the course of time we’ve seen color photography, digital photography, photography as art, photojournalism, wedding photography, pet photography, street photography, vernacular photography, moving photography and just about anything else you can think of.
Of course the simplicity of photography has progressed to the stage where it seems everyone has a camera in his or her pocket at all times. We no longer need to wait for the exposure and development of the film. But in its essence, photography is still the means to capture a moment.
