Description

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. ND Grads are made in different densities according to the level of light reduction from 1 stop to 4 stops of light. Formatt-Hitech cinema filters are made from the highest quality Schott Superwite glass. 

Graduated Neutral Density

Graduated filters have an effect that occurs on one area of the filter and transitions to clear on other areas of the filter. Typically graduated filters are used to enhance the sky or terrain, or balance the luminosity of the sky to the luminosity of the terrain. For hard and soft grad filters, colors are often deployed (such as sunset or twilight) to enhance the color of the sky.

Formatt-Hitech offers four varieties of Graduated Neutral Density Filters:

  • Soft Edge Grad
  • Hard Edge Grad
  • Reverse Grad

Soft Edge Grads

Soft Edge graduated filters transition across the filter toward the center, and although there is a horizon line, it is subtle. This allows for horizon transitions to be more easily hidden in a scene, especially with an undulating horizon line such as mountains, buildings or trees.

Roughly speaking soft edge grad filters are for wide angle lenses and hard edge filters are for longer lenses. This gives the most visually attractive effect transition at the horizon line. The Soft Edge grad is the ideal tool for balancing bright sky to a dark terrain where the horizon is uneven. Soft Edge grads are essential for both fine art photographers and professional cinematographers alike, and are the most popular grads we make.

THE NEW FIRECREST HOLDER MKII ATTACHED TO A TOKINA 11-20 T2.9 AND BLACK MAGIC POCKET 6K. WHEN PAIRED WITH THE FIRECREST ULTRA RANGE OF FILTER ALLOWS YOU TO GET CINEMA-QUALITY ND AT A FRACTION OF THE WEIGHT

A bigger polariser giving you a wider view

With recent developments in optical design, it has become more common for lenses to have larger threads. To accommodate these advancements we have expanded our CPL (circular polarising filter) to 86mm. This means wider compatibility and better performance on a range of new wide-angle lenses. It also makes it compatible with a range of cinema lenses such as the Tokina 11-20MM T2.9.

The polariser can be fitted into either included rotating ring adapter, and becomes an integral part of the holder. The polariser is operated with an easy to use thumbscrew. This allows you to set your grads and then dial in the exact

polarising effect you want. Due to its free movement, this means you can leave the polarising filter (CPL) attached at all times and simply turn off the effect if not wanted. The construction of the filter also means you can use the CPL filter as an independent filter without the need of the holder.

More step rings, more flexibility.

For improved performance on an even wider range of lenses, the holder now ships with two rotating adapters as standard. These adapters allow the lens to sit closer to the filters helping with wide-angle photography. The kit

includes an 86mm - 86mm rotating adapter and a 86mm - 82mm adapter. For best performance on 77mm and smaller wide-angle lenses, it is recommended to use the included step rings from the 86-86mm rotating adapter.
