Tilta Illusion 95mm Full Spectrum ND Filter

FSND(Full Spectrum Neutral Density) filter is a kind of neutral density filter that consistently reduces the intensity of light, without significantly affecting the color.

The FSND filter reduces light, which is extremely beneficial for shooting in bright conditions, especially when a larger aperture or slower shutter speed is required. By using FSND filters, photographers gain enhanced control over exposure to achieve the desired effects, such as blurring motion, capturing flowing water, or creating long exposure effects.

In certain scenarios, such as shooting High Dynamic Range (HDR) or capturing scenes with a bright sky and darker landscapes, can vary significantly. Utilizing FSND filters aids in balancing these brightness levels, ensuring a more uniformly exposed shot and preventing issues of overexposure or underexposure.

While producing accurate colors, using FSND filters ensures light reduction. Testing indicates that FSND filters uniformly reduce the levels in the light spectrum, meaning the overall spectral curve remains consistent. This means that light intensity for various colors is proportionally diminished, and does not result in color bias.
