The Ice 77mm HB760 Infrared Filter is 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 Ice 77mm HB760 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 760nm 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.

Related Questions and Answers

Q: 1. How well will this filter work in a snowy environment like Yellowstone in the winter?

A: While you can use an infrared filter to photograph snow, snow will still appear white. One issue with photographing in snowy conditions is the sky is normally overcast with clouds. The strongest infrared images tend to occur on clear, sunny days and with lots of foliage in the scene (foliage which is usually absent in the winter). That being said, if you capture images in the snow on a clear, sunny day and there are evergreen trees/bushes or other plants/trees that still have visible leaves that reflect infrared lighting, you would get dramatic images in these circumstances. Typically, when using the R72 infrared filter, the blue color of the sky will be darkened, while green foliage, like trees and grass, will appear in snow-like tones.

Q: 2. will this work on sony alpha cameras? i heard you need to modify the camera in order for this to work? I have a7s and a6500

A: The filter works perfectly without any changes to the camera, do you need to do some post processing and you can check on YouTube. I highly recommend the filter

Q: 3. What is the wallet?

A: Unfortunately we do not have a photo of the wallet but it is made to hold the filters and is included with Ice Infrared HB760/850/950 Set with Wallet (82mm)

Q: 4. What is the response curve of this filter?

A: Unfortunately, the Ice 77mm HB950 Infrared Filter does not have a published response curve according to the manufacturer.

Q: 5. Can I hand-hold a camera with this filter on and take pictures of the sun's sunspots?

A: The Ice Magco Solar ND100000 ND Filter with Magnetic Adapter Ring (77mm, 16.5 Stop) could be used for photographing the sun, but only for very short-term use. This filter does not protect your eyes against UV and IR light. Instead, get the MrStarGuy 77mm Thread-in White-Light Solar Filter, BH #STSG77MMSO. This filter protects your eyes from damaging UV and IR as well as white light. You can shoot at a fast enough shutter speed to hand-hold the camera.

Q: 6. How many stops of light do you loose with this filter?

A: I don't have the exact figures with me here, but on a bright full-sun day my exposures using a Canon 5D MKIV and Canon 70-200 2.8 IS was 30 seconds @ f/2.8, 200 ISO. Hope that helps!

Q: 7. Will this filter work with a Canon 5D Mark II and a Fuji XT-3?

A: Neither the Canon EOS 5D Mark II nor the FUJIFILM X-T4 Mirrorless Camera have a specified spectral sensitivity from the manufacturer. That being said, this can be used with either camera, though you will need to use longer exposure times. For better IR sensitivity you would need to have the camera sensors modified. In terms of fitting on a lens, this will depend on the specific lens you are using.

Q: 8. Does this thing really work? How many Stops should I anticipate opening up? Do I compose without the filter then screw it on the lens?

A: You would need to pre-focus and compose your shot prior to screwing on the Kase 77mm IR 720 Infrared Threaded Filter. The results may vary when using this filter.

Q: 9. Hello. Does this filter have the same difficulty with wide-angle lenses that most multi-coated cut filters have? I.e., inconsistent, off-axis effectiveness/banding beyond ~ 60 degree FOV. Thanks in advance!

A: Yes, this Ice 77mm UV/IR Cut Filter has the same wide angle issues many filters have. The IR filtration makes no difference, as far as the wide angle effectiveness goes.

Q: 10. I was planning on shooting both in color and B&W in raw format and was wondering what type of a result i will get in color mode?

A: A RAW color image shot with an infrared filter will produce a yellow/red image with blue foliage.
