This Ikelite Yellow Barrier Filter for Dive Maskfrom Ikelite Yellow Barrier Filter for Dive Maskis designed to fit over a diving, scuba, or snorkeling mask. It can then enable the viewing of fluorescence being emitted by fish or coral that are exposed to a blue or UV excitation light.

Fluorescence is a process that begins with chemical compounds called fluorophores as they absorb light energy from an outside source. Atoms and molecules within the fluorophores then emit their own light at lower energies and wavelengths that correspond to the original light source, making the fluorophores appear to glow. The proteins in many fish, coral, or other underwater life contain fluorophores, which create unusual or unique viewing opportunities. Since blue or UV wavelengths with their relatively high energy levels can yield the most intense fluorophore reactions, blue or UV light sources are considered ideal for producing the most colorful fluorophore effects.

However, because the light from a blue or UV lamp used to excite the atoms and molecules within the fluorophores is more intense than the lower-energy fluorophore glow, such lamps can end up obscuring that glow from fish or corals. The Ikelite Yellow Barrier Filter for Dive Mask makes it possible to perceive fluorescence from underwater life by blocking the light from a blue or UV excitation light; allowing the resulting glow to be seen through the filter and the diving, scuba, or snorkeling mask it is placed over.

This Ikelite Yellow Barrier Filter is constructed from rigid acrylic that is 6" high, up to 2.25" wide, and is shaped to accommodate the nose pocket on a diving, scuba, or snorkeling mask. It also features an adjustable, nylon woven-elastic head strap with two tri-glide buckles that allows this wearable filter to fit a circumference range of 19" to 36".

Q: 1. How many 6x7 films will it fit? If I have a strip of 6x7 film without cutting it, will it still be able to hold it without damaging it?

A: 2 frames will fit.

Q: 2. Will this filter kit attach directly to the body of the GoPro Hero 5, or is the GoPro Super Suit required?

A: The Flip Filters FLIP7 1-Filter Kit with DIVE Filter for GoPro HERO Cameras will require the GoPro Super Suit Dive housing for attachment with the GoPro Hero 5. The Flip Filter will not attach directly to the camera.

Q: 3. Can this also be used on an underwater housing?

A: Of course. I am using it on the sony housing.

Q: 4. will this fits on gopro hero? (the simple one with enclosed battery), thanks

A: It fits my hero 3+ dive housing. Not sure about older versions.

Q: 5. Can I download this plug-in on one computer and install it on another that is not on the internet?

A: An active internet connection is required to activate the SPC Magic Mask (Download). While you may be able to download the software on one computer and transfer the downloaded file to another computer, the second computer would need internet access to initially activate the software on that computer.

Q: 6. will this fit the hero?

A: Fits on my Hero 4

Q: 7. Will this fit the GoPro Session without any diving housing? I need an adapter that works for 58mm filters, and the other standard Revo filter (AC-H3FM-52) is a 52mm adapter.

A: No it is designed specifically for the HERO3+/HERO4 Dive Housing.

Q: 8. Is this glass or plastic?

A: Needed to pull the filter out of the case. I believe it is plastic making it a slightly weigh slightly less than glass.

Q: 9. I usually cut 6x7 film into strips of 3 (with 1 extra frame at the end), but this will not fit in some holders if they are not open on one end for the film to extend out. Will this holder allow for a film strip that is wider than the holder without pinching/creasing it?

A: No, this Lomography DigitaLIZA 120 Scanning Mask only has a scanning area of: 7.2 x 2.3 inches (184 x 58mm). While it does not define the frames individually, so you can scan overlapping exposures, doubles, triples, and panoramas. It does not allow anything larger than the given scanning area.

Q: 10. Will this fit Hero 4?

A: Yes, it is the same housing as the 3+
