More Information

Colour filters are a crucial tool in the art of visual composition. They are widely used not only in photography and filmmaking but also in other areas such as astronomy, lighting design, and even in the healthcare industry for certain types of vision correction. In modern photography, digital colour filters are applied using post-production software, but physical colour filters remain valuable for specific lighting or camera settings. Their primary function is to control the light entering the camera, ensuring that only the desired wavelengths reach the sensor, which can drastically alter the final image's tone and mood.
