Photography is a technology and artistic practice based on the principles of optics and chemistry, involving the capture of light to create a lasting image. At its core, the process requires a controlled mechanism to focus visible light onto a light-sensitive medium. Historically, this medium involved chemical reactions on materials like treated plates or film; modern digital methods utilize electronic sensors that convert incident photons into measurable electrical signals. The resulting images can be captured in various formats, from physical prints to digital files, documenting light patterns and spatial information. The development of this field has continuously advanced the methods for controlling exposure, capturing depth, and manipulating the resulting visual data.
