POLARIZER FOR NIKON/CANON
The polarizer is one of the few truly useful filters.
CDSL polarizer is a device that only allows the passage of polarized light according to a certain plane.
They are suitable for film and digital and cannot be digitally simulated. They increase the saturation of colors, eliminate light reflection.
Like any filter placed between the lens and the subject to be photographed alters the color features, CDSL filter has a guaranteed color distortion to a delta 1.
This variation is not perceptible to the human eye.
