Brighten
dark photos.
Lift the shadows, not the whole photo — or the windows go white. The tool below does that automatically in your browser and saves at full size. Further down: how to shoot brighter rooms in the first place, and how HDR works.
Shoot it brighter
Turn every light on, curtains open
Lamps, ceiling lights, under-cabinet lights. Mixed daylight and lamps look warmer than either alone.
Shoot in daylight, not in direct sun
Mid-morning or mid-afternoon on the window side of the building. Booking.com’s own tip: “Shoot during daylight hours or make sure your photos are well-lit.”
Expose for the room, not the window
On iPhone, tap the room to focus, then drag the exposure control next to the focus box up. On Android, tap and slide the exposure control the same way.
Hold still, or use something to lean on
Indoors the camera picks a slower shutter. A tripod or a shelf stops the blur that makes dark photos look worse once brightened.

Brighten it on your phone
| App | Where and what |
|---|---|
| iPhone Photos | Edit → Adjust. Raise Shadows first, then Exposure or Brilliance a little. Lower Highlights if the windows go white. |
| Google Photos | Edit → Adjust. Try “HDR effect” first, then Brightness. Pull Highlights down if the windows go white. |
| Any editor | Lift the shadows before overall brightness. Brightness lifts the windows too; shadows only lifts the dark parts. |
Tool names from Google Photos help; iPhone Photos uses the same names in Edit → Adjust.
HDR real estate photography
A single photo cannot hold both a dark room and a sunny window. HDR takes several — commonly three to five, one or two stops apart, from a tripod — and merges them. Lightroom Classic does it with Photo → Photo Merge → HDR; phones merge frames automatically. Many property photographers instead add one flash frame to the ambient frames (“flambient”) for cleaner whites. Whichever you use, watch for these:
| Problem | Cause and fix |
|---|---|
| Grey halos around windows and lamps | Strong local contrast. Turn down the HDR or detail strength. |
| Flat, grey walls | Shadows lifted too far with no contrast left. Add a little contrast back, or set the black point. |
| Neon colours | Saturation boosted with the merge. Real rooms are rarely that colourful; guests notice on arrival. |
| Blurry edges, ghost people | The camera moved between frames, or someone walked through. Use a tripod and an empty room. |
Brightening is allowed

Very dark photos may be removed for low quality, and quality removals cannot be appealed. Improving the lighting is encouraged; heavy filters are not.
California AB 723
Lighting, exposure, white balance and colour correction are excluded from “digitally altered image”, as long as they do not change how the property is represented.
Where it stops
Adding lights that are not there, swapping the view or replacing the sky changes what guests will find. That is a different edit with different rules.

Windows still white, walls still leaning?
The photo lab goes further than a curve: it recovers detail in bright windows, neutralises yellow light and straightens verticals — without adding or removing anything, and checks that. Up to 20 photos at once; the first is free.
Open the photo lab→Questions
How do I brighten a dark photo without making it look fake?
Lift the shadows, not the whole picture, and leave the brightest parts alone. The free tool on this page does exactly that: it stretches the photo’s own darkest and brightest points to black and white, then raises the darks along a curve that keeps highlights in place. Phone editors do the same with the Shadows slider.
Why do my indoor photos come out so dark?
The camera sets exposure for the whole scene, and a bright window pulls everything else down. Tap the room to set exposure there, turn on every light, and shoot in daylight.
What is HDR real estate photography?
Taking several shots of the same room at different exposures — usually three to five, one or two stops apart, on a tripod — and merging them so both the room and the view through the window keep detail. Lightroom Classic does it with Photo → Photo Merge → HDR; phones do a version automatically.
Is brightening a listing photo allowed?
Yes. Booking.com asks for well-lit photos. California’s AB 723 excludes lighting, exposure, white balance and colour correction from its definition of a digitally altered image, as long as the representation of the property does not change. Google asks for no significant alterations or excessive filters.
Does this tool upload my photo?
No. The photo is opened, brightened and saved in your browser at full size. The saved JPEG has no location data.
