The Tiffen 4x4 Double Fog 4 Filter for Photographysimulates 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 4 density provides a very noticeable 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 and grinding flat to a tolerance of 1/10,000th of an inch. This filter measures 4 x 4" / 101.6 x 101.6mm.

Q: 4. How does this mount? Is this ORCA proprietary, or universal? I'm interested in mounting to a Zacuto camera cheeseplate. I believe the Petrol PS604 does this?

A: Hi Colin The locking mechanism on these Orca pouches are quite sturdy. The pouch has a protruding cross, that marry with a sunken negative of the same shape on the bag when tilted 90 degrees. In other words, it keys into the bag at 90 degrees and locks by turning it up right. I'm not shure how this pouch or the Petrol pouch would key into a cheese plate unless you mounted the receiving key to it first. Bongo ties and stick on Velcro is how I usually go about mounting receivers to the camera.BestLouw

Q: 9. Will this work with a Pocketwizard TTL and a Profoto Air TTL remote with all it's TTL and HSS functions?

A: This will not work as TTL at all. Only straight hotshoe to fire whatever is sitting in either the 2 slots. As you can see there is no other TTL contacts on the hotshoe to talk to whatever is attached to it.I wanted to buy this as I wanted to use my Canon transmitter and a PW at the same time. Problem is they made the hotshoes too close together so it was way to tight. Additionally when I tried to trigger them both there were some problems firing to get both to work together.The most problematic was the Profoto Air TTL, it simply would not fire any of the strobes at all. I think the Air TTL is looking for the signal contacts from camera hotshoe and since there isn't any on this splitter, it doesn't want to fire.I also thought I could use this to fire my Canon transmitter AND the Profoto Air TTL together. Again it wouldnt' work and the hotshoes are too close together. I really think they need to go back to the drawing board and redo for people who use dual triggers to fire all their different strobes together.

Q: 10. Does this come with secondary safety tethers?
