The Intensifier filter by Hoya is designed to enhance color contrast within an image without unwanted polarization. It is intended to affect specific colors of the visible spectrum that pass through it, with an emphasis on the wavelengths of light responsible for the appearance of red and orange. Whites and neutral tones are preserved, and the density of this filter, 0.15, corresponds to a reduction in light entering a lens by half a stop.

This Hoya filter is made of optical glass for increased clarity and features an aluminum alloy filter ring for durability while remaining lightweight. It can also be used to reduce the appearance of light pollution in images or videos that include the night sky and illumination from artificial light sources. This effect can be achieved when this filter is used in a film camera system with daylight film installed or in a digital camera system with the daylight white balance setting selected.
