This 5 x 5" Tiffen Full Spectrum IRND Filter 5x5 6-Stopis a combination of both an infrared control filter and a 6-stop neutral density filter. An IRND is ideal for HD cameras, which have greater low-light sensitivity and, subsequently, an increased susceptibility to IR contamination. When using a standard neutral density filter to counter the increased light sensitivity afforded by the HD sensor, the effects of infrared pollution become more apparent. This filter combines an ND filter with a comparable IR control filter to eliminate the spill of infrared light reaching the sensor while still maintaining the extra exposure benefits of a neutral density filter.

This filter is constructed from Water White glass and is made using ColorCore technology, a process that involves laminating the filter substrate between two pieces of optical glass and grinding flat to a tolerance of 1/10,000th of an inch. This filter measures 5 x 5" / 127 x 127mm.

1.8 Optical Density    ColorCore Water White Glass    Enables Use of ND without IR Pollution    Maintains Color Fidelity    Ideal for HD Cameras

Infrared control filter helps to block infrared pollution from affecting the color fidelity of imagery; this enables a wider color gamut and truer colors, especially noticeable in the darker regions of the image.

1.8 neutral density filter provides a 6-stop exposure reduction.

Water White optical glass for excellent clarity.

Q: 1. Are there any seams in the fabric?

A: nope

Q: 2. can I use this with a 4x4 frame that isn't from Westcott?

A: It is possible to use it with a different frame, but you might have difficulty fastening it to the frame. Westcott has velcro that lines the frame and the diffuser, and it is quite a tight fit. But it is just a diffuser and you could clip it on. Might be a pain, and not fit exactly.

Q: 3. Does it have a seam(s) or is it just one big piece of fabric?

A: There are two (2) seams in the fabric. If the fabric was orientated vertically, there is a seam approximately 600mm in from both the left and right edges of the fabric. So there is a 1200mm centre strip of fabric in between those two (2) seams.If the fabric was orientated horizontally, there is a seam approximately 600mm in from both the top and bottom of the fabric. Again, there is a 1200mm centre strip of fabric in between those two (2) seams.Now you can make your buying decision according to your application of use.

Q: 4. Can the fabric be washed normally?

A: Yes, the following material can be washed to keep clean.

Q: 5. Can simultaneously broadcast to receivers and iPads?

Q: 6. If I have the 8X8 frames- can I use this to build a 4X4 diffuser? I know there have been issues with diffuser sizes matching frame sizes. Wondered if anyone had done this?

A: Yes. But the following adapter is needed in order to daisy chain the two frames. Westcott Scrim Jim Cine 1" Straight Frame Connector BH #WE2029 • MFR #2029 https://bhpho.to/3EhUS20

Q: 7. How do I get the creases from folds out of the fabric?
