As described above, the IR filters cut off all the visible rays of light apart from the red-light spectrum. These red light rays are called infrared (while the wavelength above these are called microwaves), but the general classification of infrared includes “near infrared”, “mid-infrared” and “far-infrared”.

What does infrared filter do?
Infrared cut-off filters, sometimes called IR filters or heat-absorbing filters, are designed to reflect or block near-infrared wavelengths while passing visible light. They are often used in devices with bright incandescent light bulbs (such as slide and overhead projectors) to prevent unwanted heating.
Do infrared filters work on digital cameras?
Most digital cameras have an infrared blocker that’s great for regular photography, but obviously not for infrared work. The filter will block out most of the visible light, only allowing infrared through. You’ll get good results but will need to adapt the way you shoot, as the filter will be dark and dense.
What does an IR filter look like?
Infrared filters block out almost all visible light, leaving only the infrared spectrum to be captured. As such, to the naked eye the filters will look almost black, with a little red tint when they’re held up to the light.
Does infrared reflect off glass?
Wi-Fi cameras rely on infrared (IR) for night vision. But IR bounces off glass —so, if you’re using your camera behind a window, you’ll only see a blurry reflection at night.
What is IR Blocker?
Block-IR consists of two layers of infrared-blocking material bonded with polyurethane, which surrounds a core of non-conductive insulation. When sealed with foil tape, it creates a barrier that locks the heat and infrared light in. Rolls are 4ft wide.
Can all cameras see infrared?
You established the fact that cameras can detect IR light. Why does one camera work but not the other one? No, the rear-facing camera is not broken. It’s designed to prevent infrared light from passing through the lens; therefore, no light is seen on the screen.
What is infrared and how does it work?
Like visible light, infrared (IR) radiation, sometimes called infrared light, is a type of electromagnetic radiation. Infrared detectors make it possible to “see” in the dark by converting heat emitted naturally by any object above absolute zero into an electronic signal, which is then used to generate an image.
Can you see through an infrared filter?
Special types of equipment can capture infrared radiation, including night vision goggles and thermal cameras. This allows you to see through certain materials, as infrared passes through them in a way visible light (which is all our eyes perceive) cannot.
Can you take infrared photos with iPhone?
The iPhone’s native camera works fine for infrared capture, though because you’ve blocked out so much visible light, it will require night mode’s long exposures. For best results, set your camera to capture RAW image files and enjoy the benefits of more post-processing control.
How do you take a picture with an infrared filter?
Put your camera on your tripod, and compose your image. Place the infrared filter on your camera, and use your autofocus as usual. Yes, it works just fine for infrared photos! Your light meter will work too but be sure to bracket on either end to make sure you have at least one usable exposure.
How do I convert my camera to infrared?
You can convert your camera to only receive infrared light by replacing the IR blocking filter with one which instead blocks visible light. This makes your camera an IR-ready tool — you can easily use it like you would normally, except it will capture infrared images.
What are infrared filters made of?
These filters are for use on cameras that are infrared sensitive. Filters are constructed of optical precision ground and polished glass. They appear completely black to the human eye. If you hold the 830nm and 850nm filter up to a bright light, you will see the light filament faintly.
How do you process an IR photo?
4) Instant Black and White infrared processing
- Open your image in Photoshop.
- Go to Image>Auto Tone.
- Next go to Image>Adjustments>Channel Mixer>Black and White with Red Filter (From there you can adjust the sliders to get the effect you want)
