Acts like a skylight in analog Kameas

Try self: turn in daylight Digi-camera, then hold the filter half before the lens. Result: blue and green do not gaudy but differentiated, that is, one can distinguish more shades of color. So before the lens screws! Can actually always stay tuned. Super: the filter holder: I have never seen such a thin. So there is no risk of shadowing.
This filter is not only cheaper than that of Hoya, B & W or Heliopan be wavelength range I personally like better range: 350 - 750 nm, the others have 300-700 nm This is me a little short wavy..
Personally, I am thrilled.
