Circular Polarizing Filter (CPL Filter: Circular-Polarizing Filter) was developed for cell phones with camera. The KF-1 is a filter that controls light surface reflections in sunny weather and increases color contrast in landscape photography.
Specifically, when shooting objects with strong surface reflections such as water, white buildings, or glass surfaces, you can cut a portion of the incoming light and control the effects of reflected light. In addition, in landscape photography, there is a irregular reflection caused by steam and dust in the atmosphere, which affects the color of the subject. It reduces the effects of reflections and allows you to shoot subjects in vibrant colors.
The KF-1 is mounted on the front of the built-in shooting lens, rotating the monitor to control light surface reflections and irregular reflections and detect the best conditions for your shot.
