Night Vision Effect for Photos
Built the way an intensifier tube works: one channel of brightness, amplified, blooming where it overloads, then given a phosphor colour. Green, amber and white tubes, with noise from a fixed seed so a batch stays consistent.

Tube colour
Green is the classic phosphor. Amber and white are what newer tubes actually use.
Amplification. High gain brightens everything and blows out anything already bright, exactly as a real tube does.
Noise uses a fixed seed, so the same photo and settings always give the same frame.

Everything this tool does
Monochrome first, colour last
The picture is reduced to one brightness channel before any tint is applied, the way a tube works. Every output pixel lies exactly on the phosphor ramp, which is checked across a whole test image.
Bloom only from bright pixels
Only pixels above a threshold contribute, so a dark scene with one lamp blooms around the lamp and nowhere else, rather than hazing the entire frame.
Screen blending
The bloom can only ever brighten. Applying maximum bloom to a fully white frame leaves every pixel at 255, with no dark rings around bright objects.
Deterministic noise
A fixed-seed generator rather than the system random source, so the same photo and settings always give the same frame and a batch stays consistent.
Three real phosphors
Green for the classic look, amber and white because those are what modern tubes actually use. All three run through the same brightness pipeline.
Gain that behaves like gain
Amplification is applied before the bloom and the tint, so pushing it high blows out anything already bright, exactly as an overloaded tube does.
Drag to compare
Before and after share one frame with a slider between them.
Six purpose-built presets
Classic green, white phosphor, amber tube, overloaded, clean optics and surveillance screen.
Batch with one ZIP
The fixed seed means a whole set gets a consistent treatment. Take everything as a single archive.
Nothing is uploaded
No server, no queue, nothing to delete afterwards. Close the tab and every trace of the image goes with it.
What each control does
Each control maps to something a real intensifier tube does. Gain is amplification, bloom is local overload, noise is the tube's own signal floor, and the phosphor decides the colour.
| Setting | What it does | Try | Good for |
|---|---|---|---|
| Green phosphor | the classic look | gain 120-150 | Films, games, most uses |
| Amber phosphor | what many modern tubes use | gain 120-150 | A less clichéd version |
| White phosphor | current generation tubes | gain 110-140 | Realistic, modern |
| Gain 100-140 | moderate amplification | noise 15-25 | Believable |
| Gain 170-200 | heavy, blows out highlights | bloom 60+ | Dramatic, overloaded |
| Bloom 40-70 | bright things flare | gain 130+ | Lights and windows in shot |
| Scanlines 20-40 | suggests a display | vignette 50+ | Screen or viewfinder look |

How to make night vision look like a tube, not a green filter
The reason most night vision filters look fake is that they are green filters. Turning a photograph green and adding some noise gets you something that reads as a joke rather than as equipment, because it keeps all the information a colour photograph has and simply tints it. A real image intensifier does not work that way. It has one channel: photons in, electrons amplified, phosphor out. There is no colour information anywhere in the chain, which is why the output is monochrome and why the phosphor colour is a display choice rather than something the device saw. So the first thing that happens here is that your photograph is reduced to brightness alone, and the tint is applied at the very end. The second thing that sells the effect is what happens to bright objects. A tube amplifies everything, and when something bright enters the frame the amplification saturates locally and light spills into the surrounding area. That is why footage from night vision equipment has streetlights and windows blooming into soft blobs far larger than the object itself. Getting that bloom right matters more than the noise or the scanlines, and it is why the bloom control here is tied to how bright a pixel is rather than applied evenly. As for subject, dark scenes with a few isolated bright points are what the effect was built around. A bright daylight photograph turned green will look like a bright daylight photograph turned green no matter what you do to it.

Set the gain, then the bloom
Gain amplifies everything. Bloom decides how hard the bright parts flare, which is the detail that sells the effect.

What an intensifier tube actually does
One channel, then a colour
An image intensifier converts incoming photons to electrons, multiplies them, and fires them at a phosphor screen. Nothing anywhere in that chain carries colour information, which is why night vision output is monochrome and why the green everyone associates with it is simply the phosphor that early tubes used. Modern tubes often use amber or white for the same reason a monitor might: it is easier on the eye over long periods. This tool follows the same order, reducing the picture to a single brightness channel before applying any colour, using proper Rec.709 weighting so green foliage reads brighter than blue sky as it would through a real device. The result is that every output pixel lies exactly on the phosphor's colour ramp: we check that the three channels stay in exact proportion for every pixel of a test image, which is what makes it look like a display rather than a tinted photograph.
Bloom is the detail that sells it
Amplification has a ceiling, and when a bright object enters the field the tube saturates around it, spilling light into the neighbouring area. It is the reason footage through night vision equipment shows streetlights as soft blobs several times their real size. Here only pixels above a brightness threshold contribute to the bloom, so a dark scene with one lamp in it blooms around the lamp and nowhere else, and the bloom is combined using a screen blend, which can only ever brighten a pixel and never darken one. That matters because an additive glow that could also subtract would produce dark rings around bright objects, which no real tube does. We verify the property directly: applying maximum bloom to a fully white test frame leaves every pixel at 255 rather than pushing anything out of range.
What people use it for
Film and video stills
Night vision is visual shorthand for surveillance and covert action, and it reads instantly.
Game art and UI
A tube effect over a screenshot suggests a scope or a helmet display without building a shader.
Halloween and horror promos
Found-footage horror leans on night vision heavily, particularly with heavy noise and vignette.
Escape room and event design
Printed night vision stills are a common prop for briefing materials and puzzles.
Social media posts
Recognisable at thumbnail size, which is what a scroll-stopping treatment needs to be.
Wildlife camera aesthetic
Trail cameras produce a similar monochrome look, so this suits nature content.
Music and album artwork
The surveillance association gives an image a specific and immediate mood.
Presentations about security
A quick way to make a slide about surveillance or low light look like its subject.
Six tips worth knowing
Dark scenes with a few bright points work best. A bright daylight photo turned green will still look like a bright daylight photo turned green.
Bloom matters more than noise or scanlines. It is the detail your eye recognises as a real intensifier tube.
Try amber or white. Green is the cliché, and modern tubes mostly do not use it.
High gain blows out anything already bright, which is correct behaviour rather than a fault. Pair it with heavy bloom.
Scanlines suggest a display rather than the tube itself, so use them when you want a screen or viewfinder look.
Export PNG. The output is a single hue with fine noise, which is exactly what JPEG handles worst.
Troubleshooting
It just looks like a green photo
Raise the bloom and the gain. Bloom around bright objects is the detail that makes it read as equipment rather than as a filter.
The whole frame is washed out
Gain is too high for a photo that was already bright. Lower it, or start from a darker image.
The noise changes every time
It should not. The generator uses a fixed seed, so identical settings give identical output. If something changed, a setting changed with it.
Scanlines look too heavy
They darken every other row, so at high values half the image is dimmed. Keep them under 40 unless you want an obvious screen look.
Frequently asked questions
Why is night vision green?
Because early image intensifier tubes used a green phosphor. There is no colour information anywhere in the device; green was a display choice, and modern tubes often use amber or white instead.
Why does this tool convert to monochrome first?
Because that is what the hardware does. An intensifier has one channel, so the correct order is brightness first and colour last. Tinting a colour photograph keeps information a real tube never had.
What makes the effect look convincing?
Bloom, more than anything else. A tube saturates around bright objects and spills light into the surrounding area, which is why streetlights appear as soft blobs several times their real size.
Why does bloom only come from bright pixels?
Because that is where a tube overloads. Applying it evenly would haze the whole frame, which looks like a dirty lens rather than an amplifier saturating.
Can the bloom darken anything?
No. It uses screen blending, which can only brighten. Applying maximum bloom to a fully white frame leaves every pixel at 255, with no dark rings around bright objects.
Why is the noise the same every time?
It uses a fixed seed rather than the system random source, so identical settings give identical output. That keeps a batch consistent and makes small adjustments predictable.
Which phosphor should I choose?
Green if you want the familiar cliché, which is right for most film and game uses. White is what current generation tubes use and looks more modern. Amber sits between the two.
What does gain actually do?
It amplifies brightness before the bloom and the tint, so raising it brightens everything and blows out anything already bright. That is correct tube behaviour rather than a fault.
Which photos work best?
Dark scenes with a few isolated bright points, because that is the situation the equipment exists for. Bright daylight photos will look like bright daylight photos in green.
Is this the same as thermal imaging?
No. Night vision amplifies the small amount of visible and near-infrared light that is already there. Thermal imaging detects heat and produces a completely different image, where a warm body glows regardless of light.
Does it actually see in the dark?
No, and neither does real night vision. It amplifies existing light, so a photograph that recorded nothing in an area will still show nothing there, only brighter noise.
What do the scanlines represent?
The display rather than the tube. They suggest looking at a monitor or a viewfinder, so use them when that is the story and leave them off when it is not.
Are my photos uploaded to a server?
No. The whole simulation and the export run in your browser using the canvas API. Nothing is sent anywhere.
Which format should I export?
PNG. The output is a single hue with fine noise, and JPEG both smears fine grain and bands large areas of one colour.
Is transparency preserved?
The alpha channel is untouched for PNG and WebP output, though the effect is normally used on a full frame.
Can I process a batch?
Yes. Add as many photos as you like and the same settings are applied to each. Because the noise seed is fixed, the whole set gets a consistent treatment.
Can the effect be undone?
No. Colour information is discarded when the picture is reduced to brightness. Your uploaded file is never modified, so keep the original.
Does it add a watermark or need an account?
No to both. No sign-up, no email wall, no daily limit and no watermark on the output.
