Turning a DSLR into a full-spectrum camera is a permanent hardware conversion, not a menu setting. A technician removes the factory UV/IR-blocking filter—often called the hot mirror—and replaces it with correctly specified clear optical glass. The modified camera can then work with visible-light, infrared, ultraviolet, or astronomical filters, but it will not automatically see every wavelength equally or function like a night-vision device.
For most photographers, the safest route is to convert an inexpensive spare body professionally. Choose full spectrum only if you genuinely want to experiment with several parts of the spectrum; choose a dedicated infrared or astrophotography conversion if you want a simpler, predictable workflow.

What “full spectrum” means
An ordinary DSLR is designed to make visible-light photographs with predictable color. Its internal filter assembly suppresses much of the ultraviolet and infrared radiation that the sensor could otherwise record. Depending on the camera, this assembly may be described as an IR-cut filter, UV/IR-blocking filter, hot mirror, or part of the low-pass/anti-aliasing filter stack. These terms are related, but they do not describe exactly the same component in every camera.
In a full-spectrum conversion, the original blocking filter stack is removed or replaced with a clear optical window. The replacement must have suitable optical quality, dimensions, thickness, and refractive properties. Simply leaving the sensor “bare” can change optical spacing, affect focus, reduce image quality, and expose the sensor assembly to unnecessary contamination. See the technical explanation from DST Photography and the conversion details from MaxMax.
“Full spectrum” also does not mean equal sensitivity from ultraviolet through far infrared. The sensor, Bayer color filters, microlenses, cover glass, lens coatings, filter, and lighting all shape the final response. A converted camera should not be treated as a calibrated scientific measuring instrument unless the entire system has been characterized.
Full spectrum versus infrared, ultraviolet, and astronomy conversions
| Conversion | What it is best for | Main advantage | Main limitation |
|---|---|---|---|
| Full spectrum | Experimenting with visible, IR, UV, and different filters | Maximum flexibility | Requires external filters, careful focusing, and more processing |
| 590 nm IR | Colorful or false-color infrared | Allows more visible light into the image | Results vary strongly by camera, lens, lighting, and processing |
| 665 nm IR | A balance of color and monochrome infrared | More flexible than a deep-IR conversion | Still requires a dedicated IR workflow |
| 720 nm IR | Conventional black-and-white infrared landscapes | Simple, repeatable IR use | Not readily switchable to visible or UV photography |
| 850–900 nm IR | Deep infrared and largely monochrome work | Less visible-light contamination | Often needs more exposure and provides little color information |
| UV-oriented conversion | Specialized ultraviolet photography | Designed around UV transmission | Requires UV-pass filters and UV-transmitting optics |
| Astrophotography conversion | Night-sky and emission-nebula imaging | Optimized for relevant astronomical wavelengths | Less convenient for general UV/IR experimentation |
A full-spectrum body becomes useful only when you control what reaches the sensor with a suitable filter.
Can your DSLR be converted?
Do not assume that any inexpensive DSLR is a good candidate. Before spending money, check the following:
- Exact model support: Conversion work, replacement glass, cable routing, sensor mounts, and calibration are model-specific. Check a specialist’s current supported-camera list.
- Live View: Strong IR-pass filters can make a DSLR’s optical viewfinder extremely dark. Live View makes framing and focusing much more practical.
- Replacement glass: Confirm that a correctly sized optical window is available. The original filter cannot simply be discarded without considering optical spacing.
- Focus calibration: Ask whether the service can calibrate autofocus for your body and, if relevant, a representative lens.
- Sensor stabilization and cleaning: Moving sensors, ultrasonic cleaning systems, and piezoelectric assemblies may require special handling after conversion.
- Lens compatibility: Some lenses produce infrared hotspots, flare, uneven transmission, or poor UV transmission.
- Value: Use a replaceable spare body, not a valuable professional or sentimental camera.
A DSLR can work without Live View, but you may need to focus and compose before fitting a strong IR filter, use a tripod, or rely on manual techniques. Mirrorless cameras are generally easier for filtered work because their electronic displays show the sensor’s filtered view, although they still require model-specific conversion and compatibility checks.
Rank #2
- Infrared filters, sometimes called IR filters or heat-absorbing filters, are designed to allow IR mid-infrared wavelengths while block visible light. They are often used in devices with bright incandescent light bulbs (such as slide and overhead projectors) to prevent unwanted heating
- There are also filters which are used in solid state (CCD or CMOS) video cameras to allow IR due to the high sensitivity of many camera sensors to near-infrared light. These filters typically have a blue hue to them as they also sometimes block some of the light from the shorter visible light and UV wavelengths
- Digital cameras are usually equipped with IR-blocking filters to prevent unnatural-looking images. IR-transmitting (passing) filters, or removal of factory IR-blocking filters, are commonly used in infrared photography to pass infrared light and block visible and ultraviolet light. Such filters appear black to the eye, but are transparent when viewed with an IR sensitive device
- The creative adjustable IR filter is a compact all-in-one variable wavelengths filter that adjusts the amount of wavelengths with just the twist of your wrist. The index marks on the filter let you know exactly the amount of wavelengths at a glance. Giving you clear and precise shots at whichever wavelengths you are using. It offers you the freedom to create different wavelengths freely
- You don't have to carry a bunch of filters for shooting. Just one filter, gives you from the range 530nm to 750nm freely
The safest option: professional conversion
A professional conversion should involve more than removing a piece of glass. Ask the service what is included:
- Removal of the original UV/IR-blocking filter stack.
- Installation of optically appropriate clear glass.
- Preservation of the correct optical spacing.
- Careful resealing and dust control.
- Testing of the shutter, Live View, autofocus, image stabilization, exposure, and sensor-cleaning functions.
- Focus calibration where the camera and service support it.
- Clear information about warranty coverage, shipping, turnaround, and limitations.
LifePixel describes full-spectrum conversions using replacement clear glass and offers DSLR focus calibration, while MaxMax describes optical-window replacement and autofocus correction. Other specialist services include DST Photography, Night Sky Camera, and Infrared Camera Conversion. Support and prices vary by model, country, shipping method, and conversion type. One indexed European listing showed an approximate service price of €225, but that is not a universal current price.

Repair common Windows errors and clear accumulated junk for a smoother, more stable PC - no reinstall needed.Free scan · no reinstallDIY conversion: what the job involves
A DIY conversion can be an educational project for an experienced camera repairer with an expendable body. It is not a universal teardown procedure. Exact screws, ribbon cables, shims, filter dimensions, sensor mounts, dust seals, stabilization systems, and cleaning mechanisms vary between models.
At a high level, the work involves:
- Finding a teardown or service procedure for the exact camera model.
- Safely isolating the camera’s batteries and power sources.
- Removing the body panels and sensor assembly without damaging ribbon cables or connectors.
- Removing the factory filter assembly.
- Installing a correctly sized, optically suitable clear window.
- Reassembling the camera while preventing dust, fingerprints, static damage, and alignment errors.
- Testing Live View, autofocus, manual focus, stabilization, cleaning, shutter operation, and exposure.
- Recalibrating focus if necessary.
The most common misconception is that the camera is converted when the original filter has merely been removed. A wrong replacement thickness can create infinity-focus problems or autofocus errors. Dust under the replacement window, a damaged cable, or a disturbed sensor alignment can make the camera less useful than before. Unless you already have the repair skills and an inexpensive body you can afford to lose, professional conversion is the better choice.
Filters you will need after conversion
UV/IR-cut or hot-mirror filter
Use an external UV/IR-cut filter for broadly normal visible-light photography. Without it, infrared and ultraviolet contamination can alter color, contrast, sharpness, and focus. A converted camera can be used for ordinary photography, but it will not behave exactly like a factory body and is less convenient because the filter must be fitted whenever you want a conventional image.
Infrared-pass filters
- 590 nm: Passes more visible light and can support strong false-color effects.
- 665 nm: A compromise between color information and a more obviously infrared look.
- 720 nm: A common choice for black-and-white infrared and some false-color work.
- 850–900 nm: Deep infrared, usually with little useful color and potentially longer exposures.
These labels describe approximate cut-on behavior, not identical results across cameras. White balance, foliage, sunlight, sensor response, lens transmission, and post-processing all affect the image.

- 📸 Unleash Your Creativity: Dreamlike Infrared Photography Unlock the world of semi-infrared photography with this classic 720nm wavelength filter. It precisely blocks visible light while allowing infrared rays to pass through, letting you capture dramatic black-and-white masterpieces with ease. Alternatively, achieve the iconic dreamy "semi-IR" look through simple post-processing (e.g., red-blue channel swapping)—transform skies into deep blues and foliage into ethereal whites, making your work truly stand out on social media.
- How are classic infrared photos created? Method 1: External Filter on Unmodified Camera Modern cameras have an internal IR-cut filter for color accuracy. Attaching an IR 720nm filter won't give you black-and-white images straight out of camera—it captures a deep red RAW file instead. Post-processing (custom white balance + red-blue channel swap) is required to achieve the classic IR look. Method 2: Camera Conversion For a smoother experience, have your camera professionally modified by removing the internal IR-cut filter and replacing it with full-spectrum transparent glass.
- 【Premium Build】 Made of 9H hardness optical glass and aluminum frame for scratch resistance and lasting durability.
- 【Easy to Use】 These filters screw directly onto the front of your lens. Compatible with any lens featuring a 52mm filter thread. Please confirm your lens thread size before purchase (e.g., Ø52mm).
- 【Shooting Tips】 For best results, set your camera to Manual (M) mode and custom white balance. Infrared light significantly extends exposure time, so a sturdy tripod is strongly recommended to ensure sharp, blur-free images.
UV-pass filters
UV photography is considerably more demanding than ordinary IR photography. You need a filter that passes ultraviolet while suppressing visible and infrared leakage, plus a lens that actually transmits useful UV. Many ordinary photographic lenses absorb or block much of the UV. A full-spectrum body alone does not guarantee UV results. The basic limitations are outlined in this overview of ultraviolet photography.
Screw-in, square, and clip-in filters
- Screw-in filters: Straightforward when the filter thread matches the lens; step-up rings can reduce the number of filter diameters you need.
- Square or rectangular systems: Useful when several lenses have different thread sizes.
- Clip-in filters: Convenient, but compatibility must be checked against the exact mount, sensor format, mirror movement, and lens design.
- Internal filters: Potentially fast to change, but DSLR mirror and shutter clearance must be verified before installation.
A filter designed for a mirrorless camera may not safely fit inside a DSLR. Check the exact body and mount rather than relying on a general product description.
Focusing, lenses, and infrared hotspots
Infrared light does not necessarily focus at the same plane as visible light through a photographic lens. This can cause front- or back-focus, inaccurate phase-detect autofocus, and softness at wide apertures. The problem has two separate sources:
- Conversion-related focus error: Incorrect replacement-glass thickness or disturbed optical spacing shifts the camera’s focus position.
- Wavelength-related focus shift: The lens may focus visible and infrared light differently, with the shift varying by lens and wavelength.
A conversion shop may calibrate autofocus for a representative lens, but that does not guarantee perfect focus with every lens, aperture, filter, or wavelength. Use Live View autofocus where it works, manual focus with magnified display, or a lens and body combination that has been properly calibrated.
Lens behavior is equally important. Some lenses produce a bright central hotspot or uneven transmission in infrared because of internal reflections, coatings, cemented elements, or other optical characteristics. A lens that is excellent for visible photography is not automatically suitable for IR. Zooms may behave differently at different focal lengths, and stopping down can change the severity of a hotspot.
Before buying lenses, check a current hotspot database or the conversion vendor’s compatibility guidance. Treat claims such as “IR-friendly” or “hotspot-free” as model-, focal-length-, aperture-, and filter-specific rather than universal.

A practical first shooting workflow
- Fit the chosen filter and verify that it clears the mirror, shutter, and lens mount if it is an internal or clip-in design.
- Capture RAW files. JPEG processing and ordinary camera profiles can discard useful information.
- Use Live View when available, especially with a strong IR-pass filter.
- Set a custom white balance. For IR, grass or another suitable reference can provide a useful starting point, but there is no universal setting.
- Start at a low or moderate ISO and inspect the histogram rather than trusting the rear-screen preview.
- Bracket exposures while learning the combination of camera, lens, filter, aperture, and lighting. There is no universal IR exposure time.
- Check focus at 100 percent and test several apertures.
- Record the setup: body, filter, lens, focal length, aperture, ISO, shutter speed, white balance, and lighting conditions.
Metering and color rendering can become unreliable with strongly filtered IR or UV work. The histogram and highlight warnings are more useful than assuming the camera’s normal metering behavior will remain accurate.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Processing full-spectrum and infrared files
A converted camera does not create finished false-color IR images automatically. Processing is part of the workflow:
- Apply or establish a useful custom white balance.
- Correct strong color casts and adjust contrast.
- Convert to black and white when color information is weak or distracting.
- Experiment with red, green, and blue channel mixing for false-color IR.
- Remove dust spots, flare, and chromatic aberration.
- Reduce or mask a lens hotspot where possible; changing lenses is often better than trying to repair a severe hotspot.
- Sharpen carefully, since IR images can contain softness from focus shift, diffraction, flare, or filter limitations.
Channel swapping—often exchanging or remixing red and blue information—is a creative option, not a fixed recipe. The result depends on the camera’s color response, filter, white balance, and editing software.
Common failure modes
“I removed the filter, but infinity focus is wrong”
The replacement optical element may have the wrong thickness or refractive properties, or the sensor may not have been reseated accurately. This is an optical-spacing problem, not something a camera menu can correct.
“Autofocus works, but the photographs are soft”
A successful shutter release does not prove focus accuracy. Phase-detect autofocus may still be calibrated for visible light, while infrared focus has shifted. Compare Live View focus, manual focus, and autofocus with a controlled target.
“The optical viewfinder is black”
A strong IR-pass filter blocks most of the visible light reaching the viewfinder path. Use Live View, compose before fitting the filter, or use a camera with an electronic viewfinder.

“There is a bright patch in the middle of every IR image”
Test another lens, focal length, aperture, and filter. A hotspot is often lens-specific and may be caused by internal reflections or coatings rather than a defective camera.
“The camera does not capture UV”
The body conversion is only one part of a UV system. The lens may block UV, the filter may leak infrared, and the subject may not provide useful UV contrast. UV-pass filtration and UV-capable optics are separate requirements.
“The camera no longer cleans its sensor normally”
Some cleaning systems are associated with the original filter assembly. Their behavior may change after conversion, and automatic cleaning should not be assumed to remain safe or effective. Ask the conversion service how it handles the specific model.
“I expected night vision”
A full-spectrum conversion broadens spectral sensitivity; it does not amplify light. The scene still needs usable illumination, and deep-IR filters can require substantial exposure or an appropriate infrared light source.
When you should not convert your DSLR
Keep the camera unmodified if it is valuable, heavily used for ordinary photography, difficult to service, unsupported by conversion shops, or important for sentimental reasons. Avoid the project if you do not have suitable lenses, cannot work around an optical viewfinder, or only want to try one occasional IR photograph.
An unmodified DSLR with an external IR filter is the lowest-risk experiment, although the factory IR blocker can make exposures very long and framing difficult. A converted used camera is often a better solution than modifying your only general-purpose body.
Which option is right for you?
- Occasional experimentation: Start with an unmodified DSLR and an IR filter.
- Several creative bands: Professionally convert an inexpensive spare body to full spectrum, then add a UV/IR-cut filter and one or more IR-pass filters.
- Black-and-white IR landscapes: Choose a dedicated 720 nm conversion for a faster, simpler workflow.
- Deep IR: Consider an 850 or 900 nm conversion or filter if monochrome output and reduced visible contamination matter more than flexibility.
- Emission nebulae and night-sky work: Choose an astrophotography-oriented conversion designed for the intended astronomical targets rather than assuming general full spectrum is automatically best. See the options described by Night Sky Camera.
- UV photography: Budget for the entire optical system—conversion, UV-pass filtration, UV-capable lens, exposure control, and careful testing.
- Normal photography: Keep an unmodified camera. A converted body with an external UV/IR-cut filter can work, but it is not an effortless replacement for a factory-configured DSLR.
Safety note
Never use an ordinary photographic filter or an unmodified camera setup to look directly at the Sun. A full-spectrum conversion does not make solar viewing safe. Direct solar imaging requires a properly rated solar filter designed for the complete optical system.
The practical recommendation
For most photographers, the sensible “super camera” is an inexpensive spare DSLR converted by a specialist, with a UV/IR-cut filter for visible work and at least one IR-pass filter for experimentation. Full spectrum offers real flexibility, but it also transfers responsibility for filtering, focusing, lens selection, exposure, and processing to the photographer.
Recommended Free Tools
If your goal is one predictable result—especially ordinary 720 nm landscape infrared or astrophotography—a dedicated conversion is usually simpler. If the camera is valuable, unsupported, or difficult to focus and service, do not convert it.
