Simply put the filter on your ringflash and a polarisation filter on your lens. Turn on the LEDs of the ringflash and point it to a mirror or another reflective surface. Rotate the filter on your lens until the reflection of the LEDs in the mirror are no visible for the camera anymore. It’s not possible to completely get rid of the reflections but almost. The only visible light is dark blue/purple on metallic objects. Now your light and your camera are crosspolarized. If you turn the filter on the light by 90 degrees, it’s parallel polarized. 180 degrees is cross polarized again. If you have any issues, don’t hesitate to contact us.
