Real Estate Camera
A realistic sky replacement is allowed on most MLSs (in your market: realestate.com.au or Domain), but a label isn't required everywhere. California's AB 723 exempts only edits such as exposure, colour and straightening that don't change how the property looks, and a new sky isn't on that list. In California, label a swapped sky and link to the original. Elsewhere, adding a label takes just one caption line and leaves no room for argument. Never use a sky to hide the area's actual weather conditions or to add a sunset where the sun doesn't set.
Sky replacement is the most common edit in listing photos, and the rules around it are the least settled. The source page for each point below is linked, with information current as at September 2026.
How common is sky replacement?
An analysis by real estate technology company Coraly, reported by Realtor.com, examined nearly 40,000 primary listing images. Almost 11% showed signs of digital alteration. Sky replacement accounted for 69% of the altered images, and more than 90% had no visible disclosure.
One reason it's so common is that plenty of trusted sources recommend it. Zillow's photography tips for sellers still say "Swap a grey sky for a blue sky" if you shot on a cloudy day.
Is sky replacement legal?
| Source | What it says about skies | What I'd do |
|---|---|---|
| California AB 723 (law) | Applies to images altered "to add, remove or change elements." Exempts lighting, colour, exposure and similar edits, but only where they don't change how the property is represented. Skies aren't specifically mentioned either way. | Label it and link to the original |
| Stellar MLS (Florida) | Twilight skies are okay if the sunset or sunrise matches the sun's actual position. It prohibits adding elements outside the owner's control. | Match the sun's direction; label it |
| Canopy MLS (Charlotte) | Prohibits adding views or elements that are "not physically possible", such as a skyline that can't be seen from the house | Never add a view when replacing the sky |
| BoxBrownie (2024 blog) | A realistic replacement doesn't need to be disclosed; one that misrepresents the local weather is unethical | Written before AB 723 came into effect |
| Zillow seller tips | Suggests replacing a grey sky with a blue one | Zillow's July 2026 post also supports clear disclosure of material AI edits |

The bottom line: none of the sources I read ban a realistic sky replacement, and nobody in California exempts one. The law's own list of exempt edits covers adjustments to the photos you took. A sky from another photo is something you've added.
When swapping the sky crosses the line
Even the most permissive guidelines have limits. BoxBrownie's post describes it as unethical to place a clear blue sky over a house "in a region known for frequent overcast weather" or to use skies that are "overly dramatic or unrealistic". The rules add a few more restrictions:
- Incorrect sun position. A sunset glowing behind an east-facing house fails Stellar's test.
- A different view. A skyline, mountain or body of water that isn't visible from the house. Canopy and Stellar both prohibit it.
- Concealing features. Using the replacement sky to obscure power lines, a cell tower or the neighbouring building. AB 723 refers to utility poles and neighbouring properties in its definition.
- Weather that conceals a problem. Blue sky and bright light over a roof that's visibly worn in person. The house matters more than the sky.
Bringing back the original sky vs replacing it
There's a middle ground, and California law treats it differently. If the sky was blue when you took the shot but appears white because the camera exposed for the house, bringing back that blue is an exposure correction. It's the kind of adjustment AB 723 exempts. Swapping in clouds from a stock photo is not.
A few ways to preserve the original sky:
- Shoot at the right time. With the sun behind you, the sky looks blue naturally. Exterior photos covers which time of day suits which way the house faces.
- Let HDR do its job. Apple says the iPhone blends several exposures "to bring more highlight and shadow detail" to a photo, and it's on by default. See taking listing photos with an iPhone.
- Reduce highlights when editing. Lowering highlights restores detail in a bright sky without inventing anything. Fixing dark photos covers the same technique for windows.
- Come back another day. For a listing that can wait, making a second trip to get a blue-sky front shot costs nothing.
If you do replace the sky
- Choose a sky that's typical of the location and season. A midday shot shouldn't have a dramatic sunset.
- Keep the sun where it actually is, and check that the shadows on the house are consistent with it.
- Don't use the sky to conceal wires, poles, towers or neighbours.
- Label it. "Sky digitally replaced" in the caption is sufficient for most platforms. Our disclosure wording guide provides templates.
- In California, add the statement and a link to the original, as the AB 723 guide explains.
Why Real Estate Camera doesn't replace skies
Real Estate Camera is our app, and it deliberately has no sky replacement. Enhance fixes exposure, white balance and verticals and recovers window detail from the photo you took. It keeps the real sky. A grey day stays grey.
That's a real limitation if your market expects blue skies on every listing. We chose it because a buyer who pulls up in the rain to a house they saw under a perfect sky starts doubting the rest of the photos. Enhance costs 1 credit a photo; see pricing. For dusk shots, read twilight real estate photos. To check whether someone else's listing has a swapped sky, see how to tell if listing photos are AI-edited.

Questions
Is sky replacement allowed in real estate photos?
Usually, but not always without a label. No MLS rule I've read bans a realistic sky swap outright. California's AB 723 exempts only edits such as exposure and colour that don't change how the property is represented, and a new sky isn't on that list, so in California, label it and link to the original.
Do I have to disclose sky replacement?
In California, the safe interpretation of AB 723 is yes. Elsewhere, the industry is divided: BoxBrownie wrote in 2024 that a realistic sky needs no disclosure, while California's newer law covers any added or changed element. Adding a label takes just one caption line.
How common is sky replacement in listing photos?
Very. An analysis by Coraly, reported by Realtor.com, found that almost 11% of nearly 40,000 primary listing images showed signs of alteration, and sky replacement made up 69% of the altered images. More than 90% of altered images featured no visible disclosure.
What's the difference between editing the sky and replacing it?
Editing adjusts the sky in your photo, bringing back blue that was blown out or reducing glare. Replacing swaps in a sky from another photo. California's law excludes exposure and colour adjustments that don't change the property's representation, so restoring your own sky is a safer edit than swapping it.
