This set consists of the "standard" filters every serious landscape photographer will eventually end up owning. It consists of the Tiffen .3, .6 and .9 Neutral Density filters (1, 2 and 3 stops respectively, or ND2 ND4 and ND8) and the Tiffen Graduated Neutral Density filter. The polariser is the famous "Moose" warming polariser.Tiffen Neutral Density Filters are reknown for their true neutrality and are based on the Kodak Wratten standard. They are a superb optical glass filter and are considered by some to be the perfect neutral density filter, and, like all Tiffen filters, have a 10 Year Warranty on the workmanship.
Neutral Density Filters
When it is desirable to maintain a particular lens opening for sharpness or depth-of-field purposes, or simply to obtain proper exposure when confronted with too much light intensity, use a Neutral Density (ND) filter.This will absorb light evenly throughout the visible spectrum, effectively altering exposure without requiring a change in lens opening and without introducing a color shift.
A Neutral Density filter reduces the amount of light passing through the camera lens without changing the color of the scene. It is especially useful in bright light conditions to help prevent overexposure. The neutral density filter also allows proper exposure at a wider lens opening for reduce depth-of-field to highlight a key subject by making the foreground and/or background out of focus.
The Neutral Density filter also allows shutter speeds to produce blurred motion effects.
Available in densities .3, .6 and .9 - These correspond to 1, 2 and 3 stops light reduction respectively and are somethimes represented as x2, x4 and x8.
Tiffen Graduated Neutral Density FIlter
Color-Grad Neutral Density FiltersOften, you want to balance light intensity between two areas within a scene. This is important outdoors to allow more sky detail while properly exposing the foreground. Exposing for the foreground will produce a washed-out, over-exposed sky, exposing for the sky will leave the foreground dark, underexposed.Part clear, part neutral density, with a smoothly graded transition between A Color-Grad ND.6-to-clear is often best for balancing sky to foregroundNeutral gray appearance drops exposure Moose Warming Circular Polariser

Moose Warming Circular Polariser
Developed by reknown wildlife photographer Moose Peterson and Hoya, the Moose filter overcomes the problem of vignetting when a 81A filter is stacked with a Polariser - particularly when used on wide angle lenses.An 81A filter is often used in conjunction with a Circular Polariser to counteract the cooling effect of the polariser and to bring the colour temperature closer to the film and digital requirements.The glass component of the Moose is made from 81A glass, thereby building in the warming effect without the disadvantage of the extra thickness of a separate filter
