The words behind the edit.

Plain definitions of the terms around AI photo editing for real estate, from exposure and white balance to virtual staging and the AI labelling rules. Each entry links to the article that goes deeper.

AI labelling requirement: Since August 2026, images whose content has been substantially altered by AI have to be marked as such, in line with the EU AI Act. This affects generative changes like virtual furnishing or added elements, not purely technical corrections such as exposure, white balance or cropping. A clear label protects your credibility and keeps the listing on the right side of the rules.
API key / BYO key: An API key is a personal access code you create with an AI provider such as OpenAI. With bring-your-own-key (BYO key) you enter that code once, and every edit then runs through your own account at the provider's real price. The platform never sees the key and never bills you per image, so you keep control of your data path and your costs.
Aspect ratio: The aspect ratio is the proportion of width to height, such as 4:3 for landscape or 16:9 for widescreen. Most property portals display and crop to landscape, so photos in other ratios get cut automatically. Shooting and exporting in the expected ratio keeps important parts of the room from being cropped away.
Batch processing: Batch processing means editing a whole folder of photos in one pass instead of one image at a time. For a listing with thirty shots this turns an afternoon of manual work into a few minutes. A tool built for daily use takes the whole set, applies consistent corrections and returns the images ready and named.
Colour cast: A colour cast is an unwanted tint over the whole image, usually yellow-orange from artificial light or blue from shade. It makes rooms look dirty or cold and gives away an amateur shot at a glance. Removing the cast is a purely technical correction and restores the true colours of walls, floors and furniture.
Compression / JPEG artefacts: Compression shrinks a file so it loads quickly, and JPEG is the usual format for photos. Too much compression creates artefacts: visible blocks and smears, most noticeable on smooth walls and in the sky. A moderate quality setting keeps files small while the eye notices no loss.
Cover image / title image: The cover image is the first photo shown in the results list, and it decides whether anyone clicks the listing at all. It should be your strongest shot, usually an inviting exterior in good light or the brightest, most spacious room. Never use a floor plan, a bathroom or a technical room as the cover, because they stir no interest.
Day to dusk / blue hour: Day to dusk turns an exterior shot taken in daylight into an evening mood with a deep blue sky and warm, glowing windows. The blue hour is the short window after sunset when the sky still holds colour. The effect makes a property look warm and inviting, but because it changes the scene substantially it should be used honestly and, where it is generative, labelled.
Decluttering / object removal: Object removal deletes distracting details from a photo, such as bins, cables, a car in the driveway or clutter on a worktop. The goal is to let the room speak rather than the mess in front of it. Removing loose objects to show reality more clearly is uncritical; it must never be used to hide structural defects like damp or cracks.
Deepfake (in a property context): A deepfake is a media file whose content was generated or changed by AI so convincingly that it looks like an unedited photo. For real estate the relevant cases are added furniture, invented views or rooms that never looked that way. Such images are exactly what the labelling requirement targets, so they must be disclosed as digitally created.
Drone / aerial photo: A drone or aerial photo shows a property and its surroundings from above, conveying plot size, location and access at a glance. It is especially useful for houses with land, commercial sites and anything where the neighbourhood is a selling point. Aerial shots need airspace rules and, often, a permit to be flown legally.
EXIF: EXIF is the hidden data a camera or phone stores inside an image file, such as camera model, date, settings and sometimes the GPS location. In a listing this can unintentionally reveal where and when a photo was taken. It is good practice to strip EXIF data before publishing so no private information travels with the image.
Exposé: An exposé is the compiled presentation of a property, bringing together photos, floor plan, key facts and description. It is the document a prospect studies before deciding to enquire or view. Strong, consistent images are what make an exposé feel professional and trustworthy.
Exposure: Exposure describes how bright or dark a photo is overall. Interior shots are often underexposed because the camera meters for the bright windows and leaves the room too dark. Correcting exposure lifts the whole image to a natural brightness so rooms look open and inviting rather than gloomy.
Exposure bracketing: Bracketing means taking the same shot several times at different exposures, from dark to bright. The frames are later merged so both the room and the bright window are correctly exposed. It is the practical basis for HDR and the reliable way to handle strong backlight from windows.
Floor plan: A floor plan is the scale drawing of a property seen from above, showing room layout, sizes and connections. It answers questions no photo can, such as how rooms are arranged and where doors and windows sit. A clean, legible floor plan is one of the most clicked elements of a listing and is often modernised from an old sketch.
Golden hour: The golden hour is the short period after sunrise or before sunset when daylight is warm, soft and low. It flatters facades, gardens and terraces and avoids the hard shadows of midday sun. Planning exterior shots for this window is one of the cheapest ways to lift the quality of a whole listing.
HDR / exposure fusion: HDR stands for High Dynamic Range and means capturing very bright and very dark areas of a scene in one usable image. In practice several frames at different brightness are merged, so the room and the view through the window are both correctly exposed. This is the standard answer to the classic problem of a dark interior against a blown-out window.
Lawn correction: Lawn correction gently revives a dull or patchy lawn in exterior shots so the garden looks cared for. Kept subtle it simply undoes the effect of a grey day or a dry spell. Pushed too far into a neon green it breeds distrust, because buyers sense the image no longer matches reality.
Noise / denoising: Noise is the grainy speckle that appears in photos taken in low light or with a phone, where the sensor has to amplify a weak signal. It makes images look rough and hides fine detail. Denoising smooths this speckle while trying to keep edges crisp, which is why brightening a dark room and denoising often go hand in hand.
Perspective correction / converging verticals: Converging verticals appear when the camera is tilted up or down, so the vertical edges of walls and doors lean toward each other. The brain expects true verticals in architecture, so a tilted room feels unsettled and cheap. Perspective correction straightens these lines so the space looks calm and professional.
Portal requirements: Portal requirements are the technical rules a property portal sets for uploaded images, covering minimum resolution, aspect ratio, file format and size. Ignoring them means the portal crops or compresses your photos in ways you did not intend. Matching the requirements gets visibly more out of the very same shots.
Reflection removal: Reflection removal takes out unwanted reflections on glossy surfaces such as mirrors, windows, screens or polished counters. Typical offenders are the photographer with a flash in the bathroom mirror or a camera silhouette on a glass table. The surface stays recognisable, but the accidental information that gives the shot away is removed.
Resolution / pixel dimensions: Resolution is the number of pixels an image is made of, given as width by height, for example 3000 by 2000 pixels. More pixels mean the photo stays sharp on large screens and in print. As a rule it is better to supply a generously sized image, because a portal can scale it down but can never add detail that was never captured.
Retouching: Retouching is the targeted correction of small flaws in an image, for example a stain on a wall, a bright reflection or a stray cable. Done with restraint it makes a photo look clean and cared for. The line is honesty: retouching may tidy the picture, but it must not misrepresent the actual condition of the property.
Sky lift: A sky lift is the gentle alternative to a full sky replacement: instead of exchanging the sky, its existing brightness, contrast and colour are enhanced. An overcast but structured sky gains depth while staying the real sky of that day. This keeps the edit closer to reality and usually needs no disclosure.
Sky replacement: Sky replacement swaps a dull grey sky in an exterior shot for a clear or lightly clouded one. It makes a facade far more inviting without touching the building itself. Because it exchanges real image content, an honest listing keeps the new sky plausible for the location and season rather than dropping in a tropical blue.
sRGB / colour space: A colour space defines the range of colours an image can contain, and sRGB is the standard that browsers and property portals expect. If a photo is saved in a wider space like Adobe RGB, portals often render it with pale or shifted colours. Exporting in sRGB is the safe choice so your images look the same everywhere they appear.
Virtual home staging / virtual furnishing: Virtual home staging fills an empty room with digitally added furniture so buyers can picture how the space could be used. It is cheaper and faster than physical staging and helps bare rooms feel liveable. Because it adds content that is not really there, it counts as a generative change and must be labelled under the rules in force since August 2026.
White balance: White balance tells the camera which light is neutral, so white walls actually look white rather than yellow or blue. Mixed light from daylight, ceiling lamps and energy-saving bulbs easily throws it off. A correct white balance is the base for believable colours across a whole set of photos.
Wide angle: A wide-angle lens captures more of a room in one frame, which is why it is the standard for interior photography. Used too extremely it distorts the space and makes rooms look bigger than they are, which disappoints at the viewing. A moderate wide angle shows the room honestly while still conveying its real size.
