TheIce HB720 Infrared Filter 55mmis designed to help capture images of how a subject reflects or transmits infrared light. Infrared light waves occupy the space in the electromagnetic spectrum behind visible light due to their longer wavelengths. Many surfaces and materials react to or emit infrared light waves differently than visible light waves, which provides the potential for photographs of subjects or subject properties that are otherwise invisible to the human eye. Such images require an infrared-sensitive medium such as infrared film or a digital photographic sensor, which may be more effective when used without the infrared-blocking filters frequently built over them.

Conventional light sources such as the sun, photographic strobes, or incandescent lighting may be used to provide infrared illumination. However, because infrared films or digital photographic sensors can be more sensitive to the relatively higher energy and shorter-wavelength visible light those sources also emit, the effects of infrared light can be otherwise obscured. This 55mm HB720 infrared filter makes it possible to capture images of how subjects are illuminated by infrared light by blocking ultraviolet, visible, and near-infrared light waves 720nm or less from the lens it is mounted onto. This filter is constructed from optical glass for clarity as well as color fidelity. It features a slim, aluminum alloy filter ring that helps prevent vignetting while remaining durable and lightweight.

Q: 2. is a five stop density enough to get the milky effect on water falls and ocean ? I am also looking to photograph motion ( still images) not sure if if i need a denser filter or five stops should suffice.

A: It would mainly depend on the amount of ambient light on the scene and your camera's settings as to if 5-stops would be enough for your needs. For most lenses, and if using the camera's lowest ISO setting, 5-stops should be enough for you to create a situation to have a shutter speed between 1/4 sec to 4 seconds, depending on the type of waterfall and available light restraints. If you use a low ISO, a mid- to small aperture, and a shutter speed between 1/4 sec to 4 seconds (or test for your needs), then the B+W 82mm XS-Pro Digital ND Vario MRC nano Filter would work for your needs.

Q: 3. My cable box has a port that reads IR. I presume that I may plug this into that port so I can place the cable box out of sight?

A: It's difficult to predict how well any ir extender will work in a particular situation. Lights can be a factor. Kopul intends this transmitter and receiver kit to be used with a switch like this: Kopul HDMI Switcher 4 x 1 B&H # KOHDSW2041 MFR # HDSW-2041. You may be able to use something like this: Kramer 3.5mm to Single IR Emitter Cable (10') B&H # KRCA35MIRE10 MFR # C-A35M/IRE-10

Q: 4. Will this kit allow an AppleTV remote to connect with and work with a 2013 MacBook Air?

A: Depending on the Apple TV remote you have, it will work with the MacBook Air. This will not control your MacBook. You can use the standard Apple remote BH #APMM4T2AMA.

Q: 5. Can I use this filter in a Sony E-Mount lens?

A: Yes, I use it with the 16-50 kit lens and fits perfect

Q: 6. Does this filter have front threads so I can attach it to a matte box or an additional filter? Thanks!

A: Yes it does have a front thread of 77mm.

Q: 7. Will this 77mm filter fit onto the Canon RF 70-200mm f2.8 lens with the supplied Canon lens hood attached?

A: Yes, the Ice 77mm Slim Circular Polarizer will fit without obstruction from the RF 70-200mm f/2.8 lens hood. The lens hood has a filter window that you may open to spin the circular polarizer.

Q: 8. Never heard of ICE. Does this produce a color cast?

A: ICE filters are made by Desmond Photographic. The Ice 82mm Slim Circular Polarizer Filter is neutral and should not have a color cast.

Q: 9. Can these filters be used together, in what combinations? Do they have threads on both sides?

A: Yes, you can stack theses filters in any order you like. Typically the UV filter goes on first, then either the polarizer or nd, keep in mind too many filters stacked can cause vignetting (darken of the edges) especially on a wide angle lens.

Q: 10. Is this a circular polarizer? Are there any pics of it?

A: Yes, it is a circular polarizer. The first photo, is a direct photo of the filter.
