Many conventional cameras can be used for near-infrared photography, where the portion of the infrared is light of a wavelength only slightly longer than that of visible light. Photography of the far-infrared spectrum with longer wavelengths is called thermography and …

2021年10月27日 · IR photography is about capturing an image by using only the near-infrared light part of the spectrum. Our eyes can see up to ca. 700nm (red) wavelength, but CCD or CMOS camera sensors are capable of detecting light up to 1100nm.

typical Si-based sensors in cameras and camcorders have sensitivities extending to about 1100 nm. In order to match the appearance of photographs to the human visual sensation, the near-infrared (NIR) part of the radiation incident on cameras is usually blocked by an IR cut-off filter.

(near) Infrared Photography: you can be on your way to taking your own ir photographs with a digital camera, $10, and good ol' fashion sunlight!

Near infrared light is in the range of 700nm-1400nm on the electromagnetic spectrum and has wavelengths that are longer than those of visible light, meaning that humans can’t see it. Infrared photography most commonly uses near infrared light.

When photographers refer to "infrared", they are usually describing the near infrared - the part closest to red light - generally between about 750nm and 1000nm in wavelength. This type of infrared energy behaves almost exactly like human-visible light.

Why use near-infrared? There is a great deal of interest about near-infrared, both from a scientific and artistic perspective. Here are some applications that use NIR signal obtained from a digital camera. In photography proper, NIR delivers sharp images with sometimes a dramatic outlook.

What if you could see ultraviolet light, like bees or juvenile trout? What if you could see infrared light, like a rattlesnake or boa constrictor? This project shows you how you can use a phone or camera, tripod, and a special filter to take pictures using near infrared illumination. It's a whole new way of looking at the world.

Near infrared is the part of the light spectrum between 800nm and approximately 1µm. Beyond that is deep infrared radiation, used in thermal imaging. Infrared radiation, although invisible to the naked eye, can be captured by the sensors of digital cameras.

2023年1月25日 · Infrared photography is done on an image sensor that os sensitive to infrared light. There are specialised cameras or a camera that you have can be modified with filters in front of the sensor to capture the infrared spectrum and block the visible light spectrum.

2019年3月6日 · People often see infrared images as being surreal and magical. The visible spectrum, which enables you to see violet, blue, green, yellow, orange, and red, falls on the light spectrum between 400nm and 700nm. When the range of light is around 700nm to 1000nm, this is referred to as near infrared.

2009年1月12日 · One of the most charming contrasting color effects you can get in photography is by using **infrared**. An easy way to understand near-infrared light is to think of it as the color of the rainbow next to red, a color that is invisible to the human eye.

Infrared or IR photography is photography of near-infrared light in the 700-1200nm range. It produces white leaves and other effects. Infrared photography is a look into the invisible world.

2020年4月12日 · Near-infrared refers to the spectrum of light just beyond the range humans can detect with their eyesight. This light range is between 700 – 1200 nm (nanometers). Another aspect of the IR spectrum, above near IR, is associated with thermal imaging.
