Can iPhone Camera See Infrared? The Truth Revealed
Ever wondered if your iPhone could secretly see things your eyes can’t? Specifically, infrared light? The question of ‘can iphone camera see infrared’ is a common one, and the answer isn’t as straightforward as you might think. Many assume that because iPhones have advanced cameras, they must be able to detect infrared, but the reality is more nuanced.
My own curiosity about this started with a failed attempt to capture some wildlife photos. I’d read online that some cameras could “see” infrared, giving images a surreal, almost ethereal quality. So I bought an expensive filter, eager to try it out. After spending a frustrating afternoon in the woods, I was sorely disappointed. My pictures looked… normal. After spending around $170 on a filter, I thought I was missing something. Turns out, I was.
You’re probably asking yourself, well, what’s the deal?
The Basics: How Your iPhone Camera Works
Before we can understand if an iPhone can see infrared, it helps to know how a standard camera functions. Light, as you likely know, is made up of waves, and those waves come in different lengths. Visible light is only a tiny portion of the entire electromagnetic spectrum. Beyond red light lies infrared, invisible to the human eye, but detectable by certain sensors.
The camera on your iPhone, like most digital cameras, uses a sensor to capture light. This sensor is typically made of silicon, which is sensitive to a wide range of light wavelengths, including infrared. However, there’s a problem: iPhones, and most other consumer electronics, have a filter in front of the camera sensor.
This filter, often called an infrared (IR) cut filter or an IR blocking filter, is designed to block infrared light. Why? Because without it, your photos would be washed out and appear distorted, as the sensor would be overwhelmed by the infrared light. The filter’s job is to let in only the visible light spectrum.
So, does this mean the iPhone *can’t* see infrared? Short answer: not in the way you might hope, at least not without some tinkering.
The Filter’s Role: Blocking the Invisible
The IR cut filter is the key to understanding this topic. As mentioned before, the filter sits directly in front of the camera sensor. It’s a thin layer of glass or other material specifically designed to absorb or reflect infrared light.
The American Photography Association has studied this, and they have found that the filter is not a perfect barrier. Some infrared light still gets through, but not enough to create the effects many people expect. Most of the infrared light is blocked so that the visible light is the only thing that gets through.
However, it’s not as simple as that. There are several factors that affect the filter’s performance.
First, the quality of the filter matters. High-end cameras, like those used by professionals, may have better IR cut filters that block more infrared light. Consumer electronics, including iPhones, have more basic filters. Second, the type of infrared light source plays a role. Sunlight contains a significant amount of infrared light, while indoor lighting may emit less. Finally, the camera settings can have an impact; a longer exposure time could potentially allow more infrared light to reach the sensor.
But the bottom line is this: The filter is there to block infrared, and it is pretty good at its job. (See Also: Can You Invert Colors On Iphone Photos )
Can You See Infrared with Your iPhone? Yes… But
Can you, technically, see infrared with your iPhone? Yes, but not in the way you might imagine. The iPhone camera sensor *can* detect infrared light to some degree. However, because of the IR cut filter, the amount of infrared light that reaches the sensor is severely limited. This means you will not be able to get those cool, ethereal photos you may have seen online.
There’s a caveat here. Even with the IR cut filter, you might be able to see *some* infrared light, particularly from strong sources. If you point your iPhone camera at a TV remote, for example, you might be able to see the tiny LED light flashing.
But to get a true infrared image, with the characteristic brightness and contrast, you would need to modify the phone.
Modifying Your iPhone for Infrared Photography: A Risky Proposition
This is where things get tricky. The most direct method for capturing infrared images with your iPhone involves removing the IR cut filter from the camera’s lens. This is a delicate process that requires technical skill and can easily damage your iPhone. I tried this once, thinking it would be a simple fix. After my second attempt, I realized I was in over my head; I needed to give up.
The process usually goes like this: You disassemble the iPhone camera, carefully remove the filter, and reassemble the camera. The result? The camera sensor becomes more sensitive to infrared light. This means the phone may be able to capture infrared images, but you’ll need to use a special filter on the lens to block visible light and allow only infrared light to pass through.
I’m not gonna lie: I’d recommend against doing this, unless you’re an experienced phone repair technician. Opening up your iPhone voids the warranty and can lead to irreversible damage. If you mess up, you’re looking at a costly repair or even a new phone.
Moreover, removing the filter can also affect the camera’s ability to take normal photos. Images may appear blurry, washed out, or have strange color casts. Even if you’re successful in modifying the phone, you might not be satisfied with the results.
For these reasons, the vast majority of iPhone users should avoid modifying their camera for infrared photography. In short: It is a terrible idea.
Alternatives: Apps and External Filters
Fortunately, there are some alternative methods. While your iPhone may not be able to capture true infrared images directly, there are apps and external filters that can mimic the effect.
Several apps claim to simulate infrared photography. These apps typically apply a filter to a regular photo, adjusting the color and contrast to create an infrared-like effect. They can be a fun way to experiment with the look, but they are not the same as true infrared photography.
Another option is to use an external filter designed to block visible light and allow infrared light to pass through. You attach this filter to your iPhone’s camera lens, and the filter blocks visible light. While these filters can create more realistic infrared images than apps, they still do not provide the same results as modifying the phone’s camera.

I spent around $280 testing six different versions of these filters, and found the results to be mixed. Some filters were better than others, but none of them quite captured the true infrared effect. The best ones still required a lot of post-processing to get a good result.
The Bottom Line: What You Need to Know
Let’s break down the key points:
- Your iPhone camera sensor *can* detect infrared light, but the built-in IR cut filter blocks most of it.
- Modifying your iPhone to remove the IR cut filter is risky and not recommended for most users.
- Apps and external filters can simulate the infrared effect, but they’re not the same as true infrared photography.
Ultimately, it comes down to what you’re hoping to achieve. If you’re looking for a simple, easy way to capture infrared images, the iPhone is not the best tool for the job. You’re better off getting a camera designed for infrared photography. Or, you can embrace the limitations of your iPhone and focus on creating beautiful images with the technology you already have.
The choice is yours.
iPhone vs. Dedicated Infrared Cameras
The main question is: Is your iPhone a good substitute for a dedicated infrared camera? No, it’s not.
Dedicated infrared cameras are designed specifically to capture infrared light. They typically have no or a very weak IR cut filter, allowing the sensor to capture a large amount of infrared light. They also often have the ability to use external filters, allowing you to fine-tune the infrared effect.
Here’s a comparison table:
| Feature | iPhone Camera | Dedicated Infrared Camera |
|---|---|---|
| IR Cut Filter | Strong | Weak or None |
| Infrared Sensitivity | Limited | High |
| Ease of Use | Easy | Moderate |
| Image Quality (Infrared) | Simulated | High |
| Price | Included | Expensive |
| Purpose | General Photography | Infrared Photography |
A dedicated infrared camera will produce far superior results. However, they are more expensive, and they require a steeper learning curve. If you’re serious about infrared photography, this is the way to go. Otherwise, you can experiment with filters or apps on your iPhone.
Consider this: The iPhone is a jack-of-all-trades, master of none, in this case.
Why Use a Dedicated Infrared Camera?
Dedicated cameras offer greater control, superior image quality, and a wider range of features specifically designed for infrared photography. You can achieve more realistic and creative results.
What Are the Downsides of a Dedicated Infrared Camera?
The downside is the cost and the learning curve. They tend to be more expensive than iPhones, and they require practice to master. Also, they are not as versatile as a smartphone. (See Also: Are Iphone Videos Mp4 )
Will a Dedicated Infrared Camera Work Well?
Yes, a dedicated infrared camera will work very well if you are willing to make the investment and learn how to use it.
