Tiffen 77mm Hollywood FX Classic Filter Kit

Soft FX Filters
Tiffen's Soft FX filters are blur effect filters. These filters have a pattern of tiny lenses that blur small details, such as wrinkles and skin blemishes, whilst keeping larger details, such as eyes, sharp. Soft F/X filters are available in most sizes, with gradations ranging from one half to five, with grade 5 having the most pronounced softening effect. This filter is particularly effective for portraits with soft focus.
This filter combines the effects of Tiffen's Soft FX series and their exclusive 812 warming filter.
Star Filters
Star filters create multiple light points, or "stars", that extend from a central light source. This can give scene lighting a more sparkling and glamorous appearance. This effect is produced by a series of fine lines etched onto the flat optical surface of a clear filter. The size and brightness of the star lines produced depends primarily on the size, shape and brightness of the light source.
You have additional control through the choice of a particular spacing between the lines on the filter. These spacings are measured in millimetres and range from 1mm to 4mm. A 1mm spacing has twice as many lines as a 2mm spacing. It will produce a brighter star for a given source. Lines in one direction produce a two-pointed star, just a streak across the centre of the light. Tiffen offers symmetrical 4, 6 and 8-point star effects as well as additional asymmetrical star patterns through their exclusive Hollywood FX series (North, Hyper, Vector and Hollywood star effects).
With an 8-point filter, the many star lines can tend to dominate the rest of the image, so it should be used with caution. Generally, medium or larger apertures are sufficient to achieve a good star effect. Always test before critical situations. These filters are supplied in a rotating mount for precise placement of the star effect.
Pro Mist Filters
Pro-Mist filters, part of Tiffen's Hollywood FX series, generally produce a highlight glow that appears more like a "halo" than the more extended glow of a fog filter. By keeping the glow closer to the subject, they create an almost pearlescent glow on the highlights. Available in different degrees of diffusion strength (with grade 5 having the strongest effect), the lower grades of the filter are also used to reduce excessive sharpness and contrast of modern film and lens combinations without detriment to the image. The Black Pro-Mist filter series also creates moderate image softening and moderate to strong highlight glow, but without as much lightening effect in shadow areas.
Both filters are also available in a "Warm" series that combines the Pro Mist effect with Tiffen's exclusive 812 warming filter.
Ultra Contrast Filters
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, overly bright highlights. Contrast reduction is achieved by lightening shadows without overexposing highlights or by darkening highlights without further darkening shadows.
Tiffen's Ultra Contrast filters work by using the ambient light surrounding the image area as well as the light within the image area itself. They reduce contrast evenly, with little or no loss of sharpness, throughout the scene, even when there are different degrees of brightness in the image. Shadow areas are opened up, revealing more detail, but without any glow or halo from direct light sources or bright reflections. Even photographing directly facing the sun produces no glow or halo. Ultra Contrast filters are available in grades 1 to 5, with No. 5 having the greatest effect.
