The Tiffen DV Film Look Kit 3 Kit is a great way to achieve pro portraiture results. It consists of the following 4x4" filters: Tiffen Digital Diffusion F/X, Black Pro Mist, Soft FX 1 and a Soft Pouch. 

Tiffen Tiffen Digital Diffusion F/X

Digital Diffusion F/X 5 Water White Glass Filter is a pro choice for high end diffusion without displaying any evidence of diffusion.

When you need to cover a multitude of physical blemishes, this filter produces a natural, even toned appearance. The smooth texture generated by this filter will flatter your subject while maintaining sharp focus.

The filter leaves no sign of tell-tale diffusion and eliminates concerns that the filter pattern will come into view on the image.

Soft FX

Tiffen Soft/FX filters are soft focus filters. They have a pattern of tiny lenslets which put smaller details, like wrinkles and skin blemishes, out of focus while leaving larger details such as the eyes sharp. Soft/FX filters are available in most sizes in grades from one-half through five, with grade 5 having the greatest softening effect. This filter is most effective when used for soft focus portraiture.

Black Pro Mist

Pro-Mist Filters, part of Tiffen's Hollywood/FX Series, generally produce highlight flare that appears more as a "halo" than does the more outwardly extending flare of a fog filter. By keeping the flare closer to the subject, they create an almost pearlescent glow to highlights.

Available in various degrees of diffusion strength (with Grade 5 having the strongest effect), the lower grades of the filter also find use in toning down the excessive sharpness and contrast of modern film and lens combinations without detracting from the image.

The Black Pro-Mist series of filters also creates moderate image softening and modest-to-strong highlight flare, but without as much of a lightening effect in the shadow areas.
