Formatt Quick Start 5 HD/DV Graduated Neutral Density Soft Edge Filter Kit - Neutral density filters have several uses and offer the possibility to achieve otherwise unachievable results. ND filters appear grey and reduce the amount of light reaching the film. They have no effect on color balance.
This kit has been specially formulated as a result of extensive research into new applications for molecular A.C.T. dyes. The filters give more of a neutral grey without the specular effects from the particulate coatings of the current neutral density and neutral density graduated filters, which allows the user more precise control.
Formatt's Neutral Density Filters are a response to the many DPs and cinematographers who find that it is important to shoot as wide open as possible to minimize depth of field, especially with HD; In response to the professional demand for an optically correct and pristine neutral density filter for HD, Formatt designed its HD Neutral Density Filters, which are the ultimate solution to enhance color contrast and are ideal for normal light reduction.
Graduated Neutral Density Soft Edge Filter
This filter enables the shooter to adjust exposure without affecting color balance. Neutral density filters are available in 1, 2, 3, or 4 stops to suit individual situations.
Often it is necessary or desirable to balance the light intensity in one part of a scene with another. This is especially true in situations where you don't have total light control, as in bright contrasty landscapes. Exposing for the foreground will produce a washed-out, over-exposed sky while exposing for the sky will leave the foreground dark and under-exposed. This filter enables cloud detail to be kept correctly exposed in the picture.
Determining which graduated neutral density filter yields ideal results for any given lighting situation takes knowledge, experience and a collection of such filters. Choose the filter strength which adjusts the lighting to stay within the exposure latitude (greatest difference between bright/dark values) which still shows details in both of the digital or film medium in use.
Speaking generally, the 2-stop value (ND 0.6 - the filter's clear portion allows 4x more light to pass vs. darkest portion) effectively compensates average bright sky-to-foreground situations, and the soft transition is applicable more often to a scene than the hard transition.
The Soft or Hard label indicates the degree of color graduation.
