The Tiffen Series 9 Warm Soft FX 4 Filterdiffuses strong light entering the lens and produces a glowing effect. While the resulting image appears softer and ethereal, there is little loss of clarity or detail. This filter works by diffusing the light entering the lens with small aberrations; by spreading the light more evenly, a soft glow is created rather than the sharp, well-defined image when shooting without a filter. This filter has a 4 density, providing a noticeable amount of softening.

This filter also combines the diffusion effect with an 812 warming filter for providing a general warmth to the image and for improving skin tones. This warming effect also helps to reduce blue sensitivity and for cutting through overly cool tones within the scene.

Tiffen filters are made using ColorCore technology, a process that involves laminating the filter substrate between 2 pieces of optical glass, grinding flat to a tolerance of 1/10,000th of an inch, and then mounting to precision metal rings. This filter is compatible with Series 9 filter holders.

Q: 5. What is the difference between the Cokin P121 and the P121S graduated neutral density filters? Both are stated to be 3-stop graduated filters. Does the s version make a more gradual transition from clear to dark than the base 121? Why would you use one versus the other?

A: I believe the S refers to soft indicating a softer transition from the neutral density region to clear. I use the S version when the scene I am trying to capture has objects (such as trees) extending into the brighter region (e.g. sky). I find the S version often works nicely when shooting some waterfalls and I want to have the foreground more exposed without introducing a hard transition line. If I'm shooting a sunset or sunrise with a strong horizon line I typically go with a harder transitioned filter.
