When measured on a spectrograph, PrimeCircle IRND X-FS Extended Full Spectrum filters performance is literally off the charts. The attenuation of light between the visible, near-infrared, and infrared spectrums is even.
This means that dark areas of your image are rendered with crisp clean blacks, giving you the absolute maximum performance from your high-native - ISO digital sensors. The greater reduction in colorcast also means that photographers and cinematographers can use calibrated sets of filters, and switch between filter densities without disrupting the color balance, and consequently the overall look, of the project.
PrimeCircle IRND X-FS Extended Full Spectrum filter is a perfect choice for filmmakers who want create a cinematic look and reduce IR contamination at the same time.
PrimeCircle Filter 4"x4" IRND X-FS 1.8 Extended Full Spectrum (6 stops)
PrimeCircle professional filters offer to filmmakers, videographers and photographers a complete line of cost-effective 4 X 4” and 4 X 5,65” filters with high grade professional quality without compromise.
PrimeCircle filters are diamond cut from German Ultra-White optical glass, the best quality solution for modern high resolution lenses! The parallel relationship between front and rear surfaces (important for the best optical performance) is verified with a laser interferometer and a densitometer is used for testing consistent density. To check proper light transmission is also used a spectrophotometer!
Two sizes are available right now: 4x4” and 4x5,65” in a full range of Technical, Diffusion and ND Grad filters for the modern digital production needs.
In the Technical section are available the IRND X-FS Extended Full Spectrum, optimized for digital sensors and reformulated with nearly flat attenuation of both visible spectrum light and infrared light, the classic ND filters, Hot-Mirror, Circular and Linear Polarizers. In the Diffusion section are availbale the Black X-Mist and White X-Mist series designed to add “magic organic” to every digital “rasor edge” shot. The ND Grad section has the basic “hard and soft” edge graudated filters important to cover several tricky light conditions or adding power and control to landscapes shots! ND Grad are often not only used to control high contrast outdoor scenes but used to design sophisticated framings.
