Exploring the Spectrum: The Basics of Infrared Photography
IR photography unveils a hidden world of wonder, transforming the familiar into the surreal. With wavelengths starting beyond the red edge of our sight, infrared (IR) captures what can’t be seen with the naked eye. I want to help you understand the intricacies of IR photography and explore the world of unseen light and captivating images.
Understanding Infrared Light and Its Photographic Implications
In the world of wavelengths, IR light exists just outside the spectrum visible to us, at around 750nm and above. The invisible light tells a quiet story of warmth and vitality, only revealed through specialized infrared filters for cameras.
The Science Behind Infrared Filters for Digital Cameras
Filters such as the R72 play a crucial role in capturing imperceptible elements. Essentially, they block visible light and only let IR waves pass.
Infrared filters are like special glasses for your camera lens. Cameras can capture light that our eyes cannot see by using IR filters. The science is simple: the filters block out visible light, allowing infrared light to pass through to the sensor.
Infrared radiation is emitted by all objects. A camera with an IR filter can capture and record this invisible light. The filter reveals a hidden world of contrasts and details, creating unique and surreal images that our eyes cannot detect.
Using an IR filter allows you to capture a different perspective in photography, showing the hidden beauty that we can’t see with our naked eyes. It’s a tool that adds an extra layer of creativity to your shots, turning ordinary scenes into extraordinary moments.
Differentiating Infrared Light from Visible and Ultraviolet Light
Our camera captures light that ranges from infrared (IR) to ultraviolet (UV). The point where IR starts marks the beginning of light beyond the colours we can see, allowing us to explore Wave Length (WL) that are usually invisible to us. IR, visible, and ultraviolet light have different wavelengths, offering great potential to push photography beyond what we can normally see.
| Spectrum | Wavelenght Range | Photographic Impact |
|---|---|---|
| Visible Light | 400 - 700 | Colours perceptible by the human eye |
| Infrared Light | 750 - 1000+ | Unseen beauty, ethereal landscapes |
| Ultraviolet Light | Below 400 | Generally filtered out in photography |
Learning about infrared-photography can be discovering something hidden and bringing it to light. Every time the camera captures an image, things that we can’t normally see become visible. Ordinary subjects suddenly shine brightly, connecting what is seen with what is not seen.
How Infrared Filters Enhance Your Photography
Discover a whole new dimension to your photography with IR filters! These magical accessories transform ordinary scenes into mesmerizing, otherworldly landscapes, giving your images an ethereal quality that captivates viewers.
Setting the white balance (WB) is crucial for calibrating images to achieve the desired mood and tonality. Modifying the camera sensor lets it capture invisible light, revealing a hidden world of light.
Here are a few IR shooting tips I’ve gleaned from my experience:

Techniques and Tips for Mesmerizing Infrared Photography
To do IR photography, you need to be creative and have a good technical knowledge of the camera. Remember the IR Filter blocks out visual light once you attach the filter you’ll see nothing in the viewfinder.
Setting Up Your Camera for Infrared Shooting
First, set a custom white balance to capture the infrared light. This preliminary adjustment is something of a ritual; it’s where the dance with light truly begins. Not sure if you can set a custom white balance? Check your manual or check YouTube for the instructions. Look around for something green: tree branches, grass etc… take a shot without the IR filter on. Another way not often used is to use a grey card.
Post-Processing Infrared Images for Dramatic Effect
After capturing those raw infrared photos, it is in post-processing that the real transformation occurs. Investing time in Adobe Photoshop, particularly with the channel mixer, articulates the ethereal qualities of the capture.
- Open the IR image in Photoshop.
- Dive into the Channel Mixer and swap red and blue channels to enhance contrast.
- Adjust the white balance for that dreamy, surreal feel.
- Fine-tune levels to add depth and richness to your image.
- Apply a subtle vignette for the finishing touch.
You can also convert the image to Black & White. The truth is, some of my best B&W images started as IR photos
Combining Infrared Filters with Other Lens Filters for Enhanced Artistry
Infrared is not a solo act; it harmonizes well with multiple filters. You could use a red filter with your landscape IR photography to make the sky look darker and create strong contrasts with light-coloured foliage. Or, opt for a polarizing filter to manage lens flare and elevate the visual drama of the composition.
| Infrared Technique | Purpose | Settings/Tips |
|---|---|---|

Frequently Asked Questions
Infrared filters block visible light and only allow infrared light waves through. Filters on camera lens capture “invisible light” beyond human vision.
Most digital cameras can be adapted for infrared photography by using a special filter or by removing the IR-blocking filter from the camera sensor. This makes the camera sensitive to infrared light, which is necessary for capturing infrared images.
Infrared photography can transform ordinary scenes into ethereal and surreal images. The phenomenon makes green leaves turn white and creates a dreamy effect in landscapes, enhancing the contrast between the sky and the objects. Infrared filters can also be used for unique portraits, creating distinctive skin tones and eye-catching effec
The 720nm marking on an IR filter indicates the wavelength of infrared light that the filter allows to pass through. Filters marked as 720nm (like R72) only allow light at and beyond this wavelength, typically resulting in images with prominent infrared effects where the foliage appears white and skies become dark.
To pick the right size infrared filter for your camera, check the lens diameter. Usually, the diameter is shown in millimetres (mm) on the lens or lens cap. This measurement corresponds to the filter size you need to purchase.
Deep IR filters, like the 720nm filter, only allow deep infrared light to pass, blocking most of the visible light spectrum and producing images with a distinct infrared look. Full spectrum filters allow the camera to capture all types of light, like visible, ultraviolet, and infrared. This provides flexibility to isolate different spectrums in post-processing or use specific on-lens filters for different effects.
Custom white balance is essential for accurate colours in infrared photography. Take a photo of something that reflects IR light (like green grass) using an infrared filter, then set the custom WB in your camera’s settings using this image.
Infrared images may need techniques like using a tripod for sharpness, trying different exposure settings, and possibly bracketing exposure. Additionally, focusing might need to be adjusted as infrared light can focus slightly differently than visible light.
Combining infrared filters with other types of lens filters can lead to unique artistic effects. For instance, you might use a polarizing filter to enhance sky contrast or coloured filters for creative colour effects in colour IR photography. Additional filters can reduce the amount of light that reaches the sensor. This may mean that adjustments to the exposure are necessary.
Post-processing is an important step in infrared photography to give the photos the unique visual style usually seen in IR photos. Techniques include adjusting levels and curves to increase contrast, channel mixing to swap colours (especially in colour IR), and fine-tuning hues and saturation to render the desired atmosphere and details in the image.
