Photography

Photography captures light via chemical or digital sensors to create permanent visual records of physical reality.

Modern photography evolved from Niépce’s 1826 heliograph to the 108-megapixel CMOS sensors found in contemporary flagship smartphones. The process relies on the physics of optics (lenses focusing light) and the precision of exposure settings: aperture, shutter speed, and ISO. Whether using a full-frame mirrorless Sony Alpha or a traditional Leica M-series rangefinder, the technology serves as the primary medium for global documentation, scientific observation, and high-fidelity visual communication.
