The first infrared film was developed in 1910 by Robert Williams Wood. His experimental film required very long exposures to properly capture enough light to illuminate the images.

When was infrared film invented?
In 1910, an American physicist named Robert Williams Wood sensitized his own photographic plates and produced the first known infrared photographs of various scenes.
Who invented infrared film?
American physicist and inventor, Robert William Wood, has been credited as the parent figure for infrared photography due to his extensive work in optical physics at the onset of the early 20th century.
What is color infrared film?
Color Infrared film captures invisible infrared light from the red end of the spectrum, light that’s not visible to the naked eye and characteristically turning green vegetation a bright red. Shooting analog infrared use to be complicated and expensive, results unpredictable and not making it worth the trouble.
What is infrared light in photography?
Infrared photography refers to a special type of photography using films or sensors that have infrared light sensitivity. By using infrared light in a photograph one can add special effects, like false colors, to photographs.
Why does infrared look red?
After the eye gets very hot, it glows with a dark red color. When objects get hotter, they do two things. First, they emit more light (higher intensity) and second the produce light with a shorter wavelength. Red is the longest wavelength in the visible spectrum (and blue-violet is the shortest visible wavelength).
What was infrared film used for?
The main purpose was for aerial surveillance of war-torn areas for camouflage detection. The film is known to color the infrared light reflecting from chloroplast-rich trees / leaves a hot pink color.
Why are trees white in infrared?
The most obvious change is that leaves appear bright white, almost glowing. Leaves absorb almost all wavelengths of visible light except for green, which they reflect. The amount of infrared light reflected by a leaf. In visible light, leaves are dark (reflecting only a bit of green).
Who is David Keochkerian?
David Keochkerian is a physiotherapist from France, and while he calls himself an amateur photographer, his images are anything but. Today, we asked David to talk about his stunning infrared photography, which has been featured in Photography Monthly. I first discovered infrared photos in 2010 on flickr.
How was color film invented?
A pioneering three-color additive system was patented in England by Edward Raymond Turner in 1899. It used a rotating set of red, green and blue filters to photograph the three color components one after the other on three successive frames of panchromatic black-and-white film.
What color is infrared Nike?
But, with the coming update, there are some relatively undiscernible tweaks aside from the name: for example, the “Infrared” is actually “ Radiant Red,” though likely due to its brighter exposure, the shade appears more reminiscent of older versions.
What is IR window film?
Film Ceramic IR Series offers great infrared heat rejection for optimal comfort and is available in an attractive neutral color. The Ceramic IR series was developed with a nano-ceramic technology that provides a high level of infrared heat rejection due to the absorptive technology.
Why is vegetation red in remote sensing?
Near infrared, red, green Since they reflect more near infrared than green, plant-covered land appears deep red. The signal from plants is so strong that red dominates the false-color view of Algeria below. Denser plant growth is darker red. This band combination is valuable for gauging plant health.
Does infrared work in daylight?
Because infrared cameras measure light that is not visible, they can work in darkness as well as daylight.
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.
Why do cameras show infrared?
And while our naked eyes can’t pick up on infrared light, the sensors in your phones and digital cameras can — essentially making the invisible visible. The cell phone camera is more sensitive to light than human eyes are, so it “sees” the infrared light that is invisible to us.
