The Tiffen 4 x 5.65" Ultra Contrast 1/8 filter helps open up your shadows by using the ambient light surrounding the image area as well as the light present in the image itself. It uniformly reduces contrast, without any loss of sharpness in the scene, even in the presence of different degrees of brightness.

Shadow areas will reveal more detail but without any flare or halation from direct light sources or bright reflections. The Ultra Contrast works similarly to a Tiffen Low Contrast filter, the difference being that it reduces contrast across the entire image whereas a Low Contrast filter will only open up the shadows.

The Ultra Contrast 1/8 filter is the lowest grade available for this filter. Detail in the shadows begins to be slightly more visible. Ambient light is used to achieve this effect, not just the light from the image area itself. No flare or halation is produced in the highlights.

Tiffen's ColorCore glass is produced by a process that permanently laminates the filter material between two pieces of optical glass which are polished to tolerances of one ten-thousandth of an inch, then mounted in precision aluminium rings.


- Bright lights or sunlight create problems when the ratio between highlight and shadow areas exceeds the film's latitude; if you expose for the highlights, the shadows appear without detail; if you expose for the shadows, the result is washed out, with overly bright highlights
- Contrast reduction is achieved by lightening the shadows without overexposing or lightening, or by darkening the highlights without further darkening the shadows
- Even shooting directly towards the sun produces neither flare nor halation
- Tiffen's ColorCore glass is sealed between two sheets of optical glass. In this way, Tiffen can better control the different densities of their filters and thus create more precise degrees of filtration. This process allows for greater colour accuracy compared to glass that is simply tinted and subject to variations during the dyeing process
