Transmitted light is light that passes through a transparent or translucent medium. The amount of light transmitted depends on the density of the medium and the brightness of the incident light source, with denser materials allowing less light to pass through.
In photography, understanding transmitted light is crucial for accurate exposure and image quality. Photographers use this concept when working with filters, glass, or other optical elements, ensuring that the correct amount of light reaches the film or sensor to produce well-balanced and properly illuminated images.
