Modern digital sensors are calibrated to capture a full spectrum of light, including a balance of IR and UV light that gives rich red tones and a balanced image. By blocking light in a full spectrum manner, blocking IR, UV and visible light evenly, the NATural ND filters maintain a harmony that allows the sensor to create a full and beautiful image. IR contamination is caused by an imbalance between visible light blockage and IR light, which is very common with older ND technology and avoided by using NATural NDs.
Older IRND filter technology has been shown to have some issues with consistency after extended use. Tiffen’s unique dual-layer system for reflecting IR light while absorbing visible and UV light assures that these filters will maintain their effectiveness and color neutrality for many years to come. This is especially important for customers renting filters and using multiple cameras as NATural ND filters will be the best bet for making sure all cameras are matching and reduce post production work of balancing image color shifts.
The NATural ND filters use Tiffen’s award-winning ColorCore® process for creating filters that last. By laminating the filter effect between two pieces of Water White glass, the NATural NDs have an effect that won’t scratch off or be damaged by regular day-to-day use. It also means that Tiffen filters can be resurfaced in the case they do get scratched and the effect will remain untouched and intact.
These filters have a unique bronzed look to them which comes from the dual-layer ND element. Because one of the elements is designed to reflect away IR light, the filters appear to have this brownish-red color. In fact, that color will have no impact on the image as it is being reflected away before the light can pass through and reach the lens. So far, this is the only way to assure that an ND will create a clear, neutral image and last for years and years.
