Hitech's 67mm ND Soft Edge Grad Filter Kit (3-Pack) contains the most commonly used densities of the Soft Edge Neutral Density filter including a 0.3 filter (1 stop), 0.6 filter (2 stops) and 0.9 filter (3 stops).
Neutral density (or ND) filters produce a grey neutral tone and are used in photography to reduce light, enabling more control over exposure and depth of field without affecting color contrast. These filters are clear in the bottom half of the filter with a gradual transition to the ND effect in the top half. They are primarily used for light reduction in skylines of landscape shots. Soft edge grads have a smooth transition from clear to ND.
The 67mm filters are ideal for smaller consumer DSLR lenses and mirrorless cameras. This is a perfect entry level filter system for compact cameras.
Fits the Formatt-Hitech 67mm holder system, so a single filter is usable on multiple lenses. Also fits the Cokin A Series holder.
Made from the highest quality optical resin available, with an index of refraction nearly identical to the finest optical glass.
High scratch resistance, low material fatigue, and chamfered corners to resist breakage so the filters will provide years of service.
Made in the UK using the world's most advanced, computer-controlled filter manufacturing technologies.
