How to Photograph Paranormal Activity: What Full Spectrum Photography Actually Captures vs What It Doesn't
What Full Spectrum Cameras Actually Do For Paranormal Investigations
Every consumer camera manufactured in the last several decades contains a filter that the manufacturer installed deliberately to make the camera worse at capturing light. This filter, called an infrared cut filter or hot mirror, sits in front of the image sensor and blocks near-infrared and near-ultraviolet wavelengths from reaching it. Manufacturers install it because human eyes cannot see these wavelengths, and a camera that captures them produces images that look wrong to human viewers: skin tones shift, foliage turns white, skies darken unnaturally.
Remove that filter, and the camera becomes capable of capturing the full spectrum of light that the sensor is physically capable of detecting, ranging from approximately 350 nanometers in the near-ultraviolet through the visible spectrum and into the near-infrared range up to approximately 1100 nanometers. This is what a full spectrum camera is: a standard digital camera with the IR-cut filter removed, either professionally or through a do-it-yourself modification process that requires disassembling the camera body.
The theoretical basis for using full spectrum cameras in paranormal investigation rests on a hypothesis that has been discussed in the research community since the early days of infrared photography: that whatever phenomena are associated with haunted locations, whether defined as residual energy, spiritual entities, or anomalous physical disturbances, may interact with or exist most visibly in light wavelengths outside the human visible range. If an entity or phenomenon emits or interacts with near-infrared or near-ultraviolet light without doing the same with visible light, a standard camera would capture nothing while a full spectrum camera would potentially capture something.
This hypothesis remains unproven and is genuinely contested. What is not contested is that full spectrum cameras capture more information than standard cameras, and that more information is generally preferable in investigation contexts, particularly when that additional information comes from wavelengths the investigators' own eyes cannot access.
Standard Camera vs Full Spectrum vs IR-Only
Understanding the differences between these three categories determines which tool is appropriate for which investigation scenario.
A standard consumer camera captures only the visible light spectrum, approximately 400 to 700 nanometers, thanks to its IR-cut filter. It is what most investigators are carrying when they are not using specialized equipment. For documentation of visible phenomena and for establishing a photographic baseline of a location, it is entirely adequate. Its limitation in investigation contexts is that it captures only what the human eye can already see, contributing no additional sensory range.
A full spectrum camera removes the IR-cut filter and captures visible light plus near-ultraviolet and near-infrared simultaneously. The resulting images without filtration appear pinkish or washed out because the sensor is receiving all wavelengths equally weighted. Photographers typically use colored filters in front of the lens to isolate specific ranges: a deep red or infrared pass filter to capture only IR, a UV pass filter to capture only UV, or no filter to capture the full combined range with its characteristic color shift. For paranormal investigation, the no-filter full spectrum approach is most common, as it maximizes the information captured at the cost of conventional image aesthetics.
An IR-only modified camera has been modified specifically to capture near-infrared while blocking visible and UV light, used most commonly for nighttime investigation work and security applications. IR illuminators, which emit near-infrared light invisible to the naked eye, flood a space with light that only the IR camera can detect, allowing clear documentation of a space that appears completely dark to human observers. This is the technology behind night-vision security cameras and is widely used in investigation for video documentation.
Use full spectrum for still photography investigations where you want maximum light range captured. Use IR video for continuous low-light documentation of space. Combine both with standard cameras running simultaneously to give context to any anomalies captured.

The False Positive Problem
No other area of paranormal investigation produces as much misidentified evidence as photography, and the false positive problem is the primary reason that photographic evidence has lower standing in the serious research community than audio or video documentation. Understanding the physics behind each category of photographic false positive is not merely sceptical housekeeping: it is essential to being able to identify the genuine anomalies that survive this analysis.
Spirit Orbs
The orb is the single most common and most thoroughly debunked category of claimed paranormal photographic evidence. The physics are well understood and have been documented exhaustively by both sceptics and paranormal investigators who care about evidence quality.
Most orbs are dust particles, pollen, moisture droplets, or small insects caught within a few inches of the camera lens when the flash fires. At this proximity, the particle is too close to be in focus and too close to cast a shadow, so it appears as a circular, slightly transparent disc with a soft edge. The flash illuminates it from directly behind the lens, producing the characteristic orb appearance. This phenomenon is called backscatter and it is the explanation for the overwhelming majority of orbs captured in paranormal photography.
Testing for dust orbs is straightforward: disturb the area around the camera before shooting by walking through it, and photograph immediately. The orb count will reliably increase. Photograph in still air with no recent disturbance, and it will decrease. This correlation between physical dust and orb frequency is the most reliable diagnostic test available.
Genuine anomalous orbs, in the very small number of cases where serious researchers have found photographic evidence difficult to explain through backscatter, tend to behave differently: they are internally consistent with clear density, they appear at distances that place them in focus rather than at the lens proximity that produces backscatter, they appear in sequential frames with motion consistent with an object moving through space rather than with floating dust, and they are captured on multiple simultaneous cameras from different angles in the same location at the same moment.
Lens Flares
Lens flares are artifacts produced when light from a bright source enters the lens at angles that cause internal reflections within the lens elements. They produce streaks, polygonal shapes, and circles of light that have no physical existence in the space being photographed. They are always associated with a bright light source within or near the frame: a window, a lamp, a streetlight, the moon.
Identification is simple: locate the light source causing the flare, alter the camera angle slightly, and observe whether the artifact moves in a pattern correlated with the light source's position relative to the frame. Genuine anomalous light phenomena in a space do not move in correlation with camera angle changes in the way that lens flares always do.
Mist and Fog
Breath mist in cold air is responsible for the majority of paranormal mist photographs. The photographer's own exhalation, or that of another investigator, enters the frame invisibly and is captured by the camera in exactly the conditions where paranormal activity is most likely to be investigated: cold, dark buildings. The solution is straightforward: be aware of where breath mist goes in the current temperature, exclude investigators from the frame, and note the ambient temperature in your session log.
Camera straps hanging in front of the lens produce curved, elongated mist-like artifacts that have been published as paranormal evidence more times than serious investigators find comfortable to acknowledge.
Anomalous mist that is genuinely difficult to explain through ordinary means tends to have specific characteristics that distinguish it: it appears in areas where no investigators are positioned, it persists across multiple sequential frames, it behaves with apparent internal coherence rather than dissipating randomly, and it is captured on multiple cameras simultaneously.
Shadow Figures
Vignetting, the darkening of image corners produced by certain lens and aperture combinations, is responsible for many reported shadow figures at the edges of frames. Camera shake at slow shutter speeds produces motion blur that can appear as a dark figure moving through the frame. Investigators standing partially in the frame, or reflections of investigators in glass or mirrors, produce figure-like shadows that are unambiguously photographic artifacts.
Shadow figures that represent genuine anomalous evidence appear with distinct features across multiple frames, in locations where no investigators are positioned, and are captured on multiple cameras simultaneously from different angles.
Camera Settings for Investigation
Auto mode is inadequate for paranormal photography because it makes decisions that prioritize conventional image quality over the consistent, documented conditions that evidence requires. Two photographs taken seconds apart in auto mode may have different exposures, apertures, and ISO values, making any anomaly in one impossible to cross-reference against the other.
Set your camera to manual mode and establish consistent settings for the investigation. In low-light investigation environments, you are balancing three variables.
ISO determines sensor sensitivity. Higher ISO values (1600 to 6400 on most modern sensors) allow photography in very low light but introduce noise, the random pixel variation that creates speckling in dark areas and that can be mistaken for anomalous detail. Use the lowest ISO that allows adequate exposure.
Aperture controls depth of field as well as light admission. Wide apertures (f1.8 to f2.8) admit significantly more light but reduce the zone of sharp focus, which means objects at different distances in the frame may be out of focus. For investigation photography where you want maximum detail across the full frame, f5.6 to f8 produces better overall sharpness, though it requires compensating through ISO or shutter speed.
Shutter speed below approximately 1/60 second introduces motion blur from hand movement. Use a tripod or stable surface for any shutter speed below this threshold. For stationary full spectrum cameras on tripods, longer exposures (1 to 30 seconds) capture more light with lower ISO, producing cleaner images.

Evidence That Stands Up
The photographic evidence that serious paranormal researchers treat as worth presenting has several consistent characteristics.
Figures with distinct human features visible across multiple sequential frames in a burst, in a location where no investigators were positioned and where the session log confirms no one entered the space, represent some of the strongest photographic evidence in the field's documentation.
Objects in motion across sequential shots, visible in frame one, shifted to a different position in frame two taken seconds later with no investigator nearby and with the shift exceeding what environmental vibration or settling could account for, carry significant evidential weight particularly when confirmed by simultaneous cameras.
Anomalies consistent across multiple simultaneous cameras pointing at the same space from different angles are the gold standard of paranormal photography evidence. A light anomaly that appears in the same location in the same moment on two cameras with different lenses from different positions cannot be attributed to lens flare, vignette, or single-camera artifact.
Best Practices for Paranormal Photography
Shoot in burst mode in areas of reported or observed activity. A single frame captures a moment. A burst captures motion, persistence, and behavior across time.
Timestamp every session and every photograph, either through in-camera timestamp settings or through a separate clock visible in each frame. Evidence without timestamp cannot be correlated with the session log.
Always deploy a second simultaneous camera covering the same space from a different angle. Solo camera evidence that cannot be cross-referenced has inherently lower evidential standing than evidence confirmed across multiple devices.
Log investigator positions throughout the session so that any human figure in the frame can be identified or excluded. An anomalous figure that appears in a location where the session log confirms no investigator was standing is more significant than one in an area where investigators were present.
