You’ve seen them. Maybe you were scrolling through your phone after a wedding or checking the "nanny cam" footage late at night. There’s a glowing, translucent circle hovering near someone's shoulder or floating across the kitchen. It looks magical. It looks like a visitor from the other side. People call them "spirit orbs," and for decades, these flickering bits of light have fueled ghost hunting shows and late-night internet rabbit holes.
But here is the thing.
Most of what you see in images of spirit orbs has absolutely nothing to do with the paranormal. It’s physics. Specifically, it’s a phenomenon called "backscatter."
If that sounds like a buzzkill, hang on. Understanding why these circles appear doesn't just debunk the fake stuff; it actually helps you identify the rare, truly weird anomalies that defy easy explanation. Most people get this wrong because they want to believe. It's human nature to look for meaning in the chaos of a digital photograph. We see faces in clouds (pareidolia) and spirits in lens flares.
The Science of the "Ghost" in Your Lens
When you take a photo, you aren't just capturing the person standing in front of you. You’re capturing every microscopic bit of junk floating in the air between your lens and the subject. Dust. Pollen. Pet dander. Moisture droplets.
In a normal setting, you don’t see these things. They’re too small. However, when you use a flash—especially on a compact point-and-shoot camera or a smartphone—the light source is physically very close to the lens. This is the "Orb Zone." The flash hits a dust mote, reflects back into the lens, and because the dust is so close, it’s completely out of focus.
This creates a "circle of confusion."
Basically, that tiny speck of dust becomes a giant, glowing, semi-transparent disk. It looks like it’s floating ten feet away, but it’s actually two inches from your phone. Fuji and Canon have actually published white papers on this. They don't call them spirits; they call them "orb artifacts." It's a technical flaw, not a supernatural event.
Why do some orbs have patterns?
You’ll notice that some images of spirit orbs look like they have "faces" or intricate, cellular structures inside them. Skeptics point to this as proof of nothing more than diffraction patterns. When light passes through the aperture of your camera, it bends. If there’s a speck of dust on the sensor or the lens itself, that light creates a topographical map of sorts within the orb.

It looks like a soul. Honestly, it’s just the "fingerprint" of the dust particle.
Real Orbs vs. Camera Glitches
Is every single orb just dust? Not necessarily, though 99% of them are. Paranormal researchers like the late Hans Holzer or the teams behind various long-running investigative series often look for "anomalous" orbs. To be considered even remotely interesting to a serious researcher, an orb usually needs to meet a few criteria that defy standard optics.
First, there’s the issue of self-illumination. A standard dust orb requires a flash or a strong external light source to exist. If you capture a glowing ball of light in a pitch-black room using a camera with no flash and no infrared (IR) light source, you’ve got something weird. That’s a "self-luminous" object.
Second, look at the movement. Dust drifts. It follows air currents. If you’re watching video footage and the orb makes a sharp 90-degree turn, accelerates against the wind, or stops and starts, that’s not how physics works for a piece of dander.
I remember looking at a set of photos from an old tuberculosis hospital in Kentucky. Most were clearly dust. But one showed a faint, blue-tinted sphere that seemed to be behind a wooden railing. Physics dictates that backscatter orbs must appear in front of everything because they are right against the lens. If an orb is partially obscured by a physical object in the room, it has "depth." That changes the conversation entirely.
The Digital Evolution of Ghost Hunting
We live in a world of high-res CMOS sensors and AI-enhanced post-processing. Paradoxically, as cameras get better, we’re seeing more "ghosts," not fewer.
Smartphone cameras use "computational photography." Your phone isn't just taking a picture; it’s taking ten pictures and stitching them together while using an algorithm to guess what the lighting should look like. This can create "ghosting" artifacts where a moving bug or a piece of lint is processed as a semi-transparent blur.
Digital noise is another culprit. In low light, your camera cranks up the ISO. This creates grain. Sometimes, that grain clumps together in a way that looks like a misty figure or a faint orb.

Does color matter?
In the world of paranormal enthusiasts, there’s a lot of talk about what colors mean.
- White orbs are supposedly "neutral."
- Blue is often associated with "protection" or "calm."
- Red or black orbs are—predictably—labeled as "negative" or "demonic."
There is zero scientific evidence for this. In photography, the color of an orb is almost always determined by the color of the object reflecting the light or the "white balance" settings of your camera. If you have warm, incandescent lighting in a room, your dust orbs will probably look orange or yellow. If you're outside under a blue sky, they might take on a cooler tint.
How to Test Your Own Images
If you want to be a better "orb hunter," you have to try to disprove yourself first. It’s the only way to find the truth.
Next time you see an orb in your photos, try this:
Go back to the same spot. Shake a dusty rug or a pillow. Take ten photos in a row with the flash on. You will likely see dozens of "spirit orbs." This is your baseline. It teaches you what the "fake" ones look like.
Watch for the "trail." If an orb has a slight blur or tail behind it, check the shutter speed of your camera. A slow shutter speed will turn a moving fruit fly into a "rod" or a "streaking spirit." It’s a common mistake. People think they caught a soul traveling at warp speed, but they really just caught a gnat moving at three miles per hour.
The Psychological Component
Why are we so obsessed with these images of spirit orbs?
It’s about the "need to know." We want proof that there is something after this. A glowing circle is a Rorschach test for our grief or our curiosity. We see what we need to see.

Serious investigators, like those from the Atlantic Paranormal Society (TAPS), moved away from "orb" evidence years ago because it’s so unreliable. They realized that if you can recreate a "ghost" with a handful of flour and a Nikon, it’s not very good evidence.
But.
There are still those rare captures. The ones where the camera was on a tripod, the room was sealed, no flash was used, and a ball of light still moved through the frame with intent. Those are the ones that keep people coming back.
Practical Steps for Evaluating Your Photos
Don't delete your weird photos just yet. Instead, look at them with a critical eye.
- Check the light source. Was there a mirror nearby? A window? A polished floor? Reflections are the primary cause of "stationary orbs."
- Check the weather. If it was raining or foggy, you weren't catching spirits. You were catching "liquid orbs," which are just out-of-focus water droplets. They look remarkably solid and bright.
- Examine the lens. A thumbprint smudge on a smartphone lens will create "streaking" orbs that look like they’re "leaking" light. Clean your lens with a microfiber cloth and try again.
- Look for "depth cues." Is the orb behind a chair? Is it casting a shadow? (Yes, some people claim to have photographed orbs that cast shadows). If it interacts with the 3D environment, it's worth a second look.
Most images of spirit orbs are just the world being messy. Air is thick with "stuff." Our cameras are sensitive. When those two things meet, we get circles.
If you want to find something truly paranormal, stop looking for the easy circles. Look for the anomalies that refuse to follow the rules of optics. Look for the light that shouldn't be there when the flash is off. That’s where the real mystery begins.
To get a better handle on your own photography, try taking "control" photos in various rooms of your house with the flash on and off. Compare how different types of dust or moisture appear on your specific device. By mastering the "boring" science of backscatter, you'll be much better equipped to spot a genuine mystery when it actually happens.
