Photography involves recording light or electromagnetic radiation using a camera to create durable images. The first photograph was taken in 1826 by Joseph Nicéphore Niépce using a camera obscura. Early cameras were later invented and improved upon, with the first color photograph taken in 1861. Key parts of the camera include the lens, viewfinder, aperture ring, and shutter speed dial. The camera lens focuses light beams using its focal length and different types of lenses like wide-angle, normal, telephoto, and zoom lenses serve various purposes.
