The Tiffen 4.5" Round Double Fog Filtersimulates the effects of natural fog or mist by creating a soft glow around highlights and lowering the overall contrast of the scene. When compared to the standard Fog filter, this filter places greater emphasis on lowering the contrast while maintaining sharpness and minimizing the effects of flare. The 1/2 density provides a small amount of fog effect and requires no exposure compensation.

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.

Q: 1. I was wondering if I can mount this on my 90mm smc Pentax lens for my Pentax 67II

A: No, your lens takes a 67mm bayonet filter.

Q: 2. How does this 2x2 filter attach to the front of the camera? It doesn't say what kind of attachment is needed.

A: 2x2 filters are to be placed on lights, rather than the camera itself. Certain lights will have a holder built in.

Q: 3. What's the difference between double fog 3, and just regular double fog, strength of effect?

[0.37 lb] Im such a fan of the glow I get with this filters. It basically lives on my EDC camera. Uploaded samples for reference. 5

[0.37 lb] A fellow bugshutter happens to live in an area with a lot of morning fog and cranks out great landscapes thereupon. I've tried everything short of axle grease on a clear filter to get the same effect, as it's not often foggy in Western, PA and there are tons of landscapes that would look great with it. Researching effects filters, I cam upon this baby and it seems to do the job pretty well--particularly with images and subjects under infinity. It won't completely replicate a foggy day, but if you don't want to pay for fog-effect plug-ins for you image management software, it's a great way to go. Doubles as portrait diffuser as well. Worth a look for the digital camera user. And it's a Tiffen--my own go-to for 40 years. 5

[0.37 lb] This fog filter really brings out the brighter stars in constellation astrophotography and nightscape photography. I have a comparison of no filter versus his fog filter on a blog about using fog filters at astroeow.com. 5

[0.37 lb] I'll be using this filter in a feature film we'll be shooting in about a month. It does exactly what Tiffen said it would do in their description. In our test shots it created a very nice fog effect. If you where to be shooting with any type of breeze you would have problems using a traditional fog machine. However with the fog filter you don't have to worry about the fog being blown away. Great effect. 5
