Our CPL Polarizing Filter Plus cuts reflected (polarized) light, which increases contrast and boosts colour saturation and vibrancy.Our ND64 Filter Plus blocks a fixed 6 fstops of light allowing longer shutter speeds for long exposure, and wider apertures for depth of field effects. Our Soft Grad ND8 Plus provides a fixed 3 fstop light reduction for balanced exposure and better dynamic range in graduated light conditions like you find in mountains, forests and sunsets.
