FAQ: Why Shoot Infrared Photography?

Infrared, or “IR” photography, offers photographers of all abilities and budgets the opportunity to explore a new world – the world of the unseen. Why “unseen”? Because our eyes literally cannot see IR light, as it lies just beyond what is classified as the “visible” spectrum – that which human eyesight can detect.

Why is infrared used for night photography?

The photographers use the cameras which are sensitive to visible light to take the photographs in the visible light or daylight. The infrared ray sensitive camera has the ability to focus differently as the wavelength of the infrared rays is longer than the visible light.

Do photographers use infrared?

In infrared photography, the film or image sensor used is sensitive to infrared light. The part of the spectrum used is referred to as near-infrared to distinguish it from far-infrared, which is the domain of thermal imaging. Wavelengths used for photography range from about 700 nm to about 900 nm.

What do you need for infrared photography?

All you’ll need is a tripod, a special infrared filter, and any camera that is sensitive to infrared light. With a few easy steps you’ll be shooting infrared photos in no time at all.

Why do cameras capture infrared?

These cameras use infrared sensors to detect wildlife by sensing temperature differences and heat signatures. In trail cameras, infrared technology is also used for night vision and capturing nocturnal wildlife.

Does infrared work in daylight?

Because infrared cameras measure light that is not visible, they can work in darkness as well as daylight.

What do infrared cameras detect?

Thermal detection An infrared camera detects the thermal energy or heat emitted by the scene being observed and converts it into an electronic signal. This signal is then processed to produce an image. The heat captured by an infrared camera can be measured with a high degree of precision.

What does infrared mean in photography?

Infrared photography is a look into the invisible world. The human eye can see wavelengths from about 400nm-700nm (from purple to red); infrared is the light beyond 700nm. IR photography can be done with either infrared film, or a digital camera, and typically involves near infrared light in the 700nm to 1200nm range.

Do you need IR filter?

There are several good reasons for using an IR-cut filter. Using a color camera to achieve realistic colors in white light requires an IR-cut filter. A CCD color camera in daylight without an IR-cut filter will therefore see a significant amount of infrared light resulting in strange colors.

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.

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.

What does infrared film do?

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.

How do you focus an infrared filter?

To use infrared focus marks, you must first set your focus before placing the IR filter over the lens. After attaching the filter to the front of the lens, you then have to ‘shift’ the focus by the amount shown using the infrared focus marks.

What is the difference between infrared camera and thermal camera?

Active IR systems use short wavelength infrared light to illuminate an area of interest. Some of the infrared energy is reflected back to a camera and interpreted to generate an image. Thermal imaging systems use mid- or long wavelength IR energy. Thermal imagers are passive, and only sense differences in heat.

How does IR photography work?

Infrared film works by being formulated to record infrared light particles. The catch is that these films are also receptive to light from the visible spectrum as well. To solve this problem and in turn make photos using infrared film, you will need an infrared filter for your lens.
