👉 Camera math is a set of mathematical formulas used to convert sensor data, such as pixel values and lens characteristics, into real-world measurements like focal length, aperture, and depth of field. It involves understanding the relationship between the camera's optical elements, including the lens, sensor, and focal length. Key concepts include the crop factor (which accounts for the reduced effective sensor size due to lens design), the focal length transformation (which converts linear measurements on the sensor to equivalent distances in the scene), and the aperture calculation (which determines the depth of field based on aperture size and focal length). These formulas enable photographers to accurately adjust camera settings for desired creative effects, ensuring proper focus, exposure, and composition.
