PrimeCircle ND glass filters produce a grey neutral tone and are used to reduce light, enabling more control over exposure and depth of field without affecting color or contrast. ND Glass filters are especially useful in bright light conditions to avoid overexposure. When using wider lenses they adjust exposure correctly, allowing for reduced depth of field.
This enables highlighting of the principal subject and taking the foreground or background out of focus.
PrimeCircle Filter 4"x4" ND 2.4 Neutral Density (8 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.
