Infrared photography unlocks a hidden dimension beyond the visible spectrum. Foliage turns luminous white, skies deepen to near black, and familiar scenes take on a surreal, dreamlike quality. By shooting in the Infrared spectrum (590nm to 950nm), photographers can create images with striking contrast where vegetation glows with ethereal tones and skies take on dramatic moods that challenge our perception of color and contrast in the natural world.
Essential Guide to Infrared Filters
What is Infrared Light?
The human eye sees only a narrow slice of the electromagnetic spectrum, ranging from approximately 380 to 720 nanometers. Just beyond that lies infrared light, beginning around 720nm. While invisible to us, infrared is something digital camera sensors can detect (unless it’s blocked by the built-in infrared cut filter that comes standard in all digital cameras).
Infrared photography transforms the ordinary into the extraordinary. For photographers who enjoy black and white imagery, shooting in IR opens up an entirely new creative frontier filled with dramatic contrast, glowing highlights, and unexpected textures.
To capture infrared images, photographers typically use one of two approaches:
- Unmodified camera: Capable of capturing Infrared light with long enough exposure
- Full Spectrum converted camera: Capture Infrared light with normal exposure times
What You'll See in Infrared
Infrared photography reveals a world that looks nothing like what we see with the naked eye. The results range from surreal false-color landscapes to striking, high-contrast black and white images, transforming ordinary scenes into something truly otherworldly. Although the following are examples of what you can expect in IR, one of the best things about shooting in IR is getting results you least expect.
Foliage and Vegetation
Plants, grass, and leaves are highly reflective in the infrared spectrum, often appearing to glow bright white, creating a soft, dreamlike effect. This signature “white foliage” look is one of the most iconic features of infrared photography.
Skies, Water, and Atmosphere
Clear blue skies absorb much of the infrared light, rendering them dramatically dark, sometimes nearly black. Clouds, by contrast, reflect IR and can appear bright white and highly defined. Bodies of water such as lakes, rivers, and oceans typically absorb IR light as well, creating rich, inky-black surfaces that contrast beautifully with glowing landscapes.
Skin and Portraits
Infrared light penetrates skin slightly deeper than visible light, softening textures and reducing blemishes. The result is smooth, porcelain-like skin tones that give portraits a unique, ethereal quality. However, IR can also highlight veins or features beneath the surface, depending on the filter used and lighting conditions.
Clothing, Dyes, and Fabrics
Clothing and synthetic materials can behave in unexpected ways under infrared light. Some dark fabrics become translucent or take on completely different tones, depending on the dyes and weaves. Black cotton might appear light gray, while synthetic fabrics could glow or lose opacity altogether. This unpredictability adds an exciting experimental component when photographing fashion and portraiture.
Architecture
Concrete, stone, and certain metals reflect infrared in distinctive ways. Buildings can take on a ghostly appearance, especially when surrounded by glowing vegetation and contrasted against deep black skies. Reflections in windows or metal surfaces can also be enhanced or altered by the IR spectrum.
Infrared Camera Setup
Here are a few important considerations when shooting IR for the first time:
- Shoot in RAW for better post-processing control.
- If you're shooting with an unconverted / default camera, focus before attaching an IR filter as IR filters are opaque to visible light.
- If you're shooting with an unconverted / default camera with external IR filters, using a tripod and remote shutter operation is essential to achieve sharp long exposures.
- Set custom white balance on foliage or grass for more neutral tones.
- Review the cameras histogram for exposure validation, not the cameras LCD screen—IR affects exposure differently than visible light and the LCD screen will deceive you.
Infrared Post-Processing
Here are a few helpful tools during the post-processing of your image to help maximize the surreal and otherworldly nature of your IR photos:
- Channel swapping (which switches the color information stored in the red and blue channels) helps create unique color effects and opens a lot of creative freedom on how the final image will look.
- Converting to black & white. IR captures pair very well with black and white conversion, maximizing the effect of the unique tonal qualities of photographing in the IR specturm.
- White balance correction is one to play with. See how it impacts different sections of the image for more creative freedom.
- Contrast and clarity adjustments will play a large role in how dramatic the final image will be, especially when paired with the above adjustments.

What Is a Full Spectrum Camera Conversion?
A full spectrum camera conversion is a modification process where the internal infrared-blocking filter (known as the hot mirror) is removed from a digital camera. This allows the camera sensor to record both visible and Infrared light, and most importantly it allows you to shoot normal shutter speeds.
The Modification
The internal hot mirror filter (IR/UV cut filter) is replaced with a specialized full spectrum filter that allows the full range of light, roughly 300nm - 1100nm) to reach the sensor.
Versatility
A full spectrum camera on its own does not limit the type of light captured; it captures both visible and infrared light, producing a very red and unusable image without filtration. However, by adding external filters, photographers can selectively capture:
- Infrared-only by using 590nm, 720nm, 850nm or 910nm filters
- Ultraviolet-only
- Combined bands (e.g. visible + IR, for low-light or artistic effects), or
- Revert back to default color science with our CSF #3 filter
Common Uses
- Infrared photography (artistic, landscape, forensic, and scientific imaging)
- Astrophotography
- Low-light or Night Photography
- UV photography (e.g. flouresence and skin analysis)
- Archeology and conservation work
Considerations
- A camera converted to full spectrum requires using external filters to isolate the desired spectrum.
- Autofocus calibration may be affected, more so in DSLRs than in mirrorless cameras which rely on phase contrast for autofocusing.
- Mirrorless cameras are ideal since you "see" through the sensor, making focusing easier in IR.
- Normallly photographers will dedicate a secondary camera to IR, and keep their primary with default color science. However, our CSF #3 filter will allow you to switch back to default color science.
