Real estate photography glossary: 50 terms, plainly defined

Capture and camera

• Focal length (full-frame equivalent): How wide a lens sees, given as the focal length that would show the same view on a full-frame (35 mm) camera, so phones and cameras can be compared; the smaller the number, the wider the view. In our measurement of 80 professional listing interiors, the median was 18 mm, with the middle 80% between 15 and 25 mm (what makes listing photos look professional).
• Ultra wide (0.5×): The iPhone's Ultra Wide camera, chosen with the 0.5× button: a 13 mm equivalent lens with a 120° field of view on every multi-camera iPhone 12 and newer. It fits a small room but stretches anything near the edges of the frame, so use the 1× camera (24 to 26 mm) whenever the room fits (iPhone camera settings).
• Field of view: The angle of a scene that a lens takes in, usually given in degrees. A wider view fits more of a room but stretches objects near the frame edges, and below about 22 mm equivalent that stretching can't be corrected afterwards the way lens curvature can, which is why professionals avoid the extreme.
• Camera height: How high the lens sits above the floor. For most listing interiors the guidance is about chest height, roughly 4 to 5 feet (HousingWire says about 5 feet, HomeJab 4 to 5), a little lower in kitchens and dining rooms, and 36 to 48 inches in bathrooms by Photography for Real Estate's figure (how to take real estate photos with an iPhone).
• Level camera (straight verticals): A camera held upright, tilted neither up nor down, so walls and door frames stay vertical in the photo. In our measurement of 392 professional listing photos, the median lean was 0.00° and only 7 leaned more than 1°; on an iPhone, turn on Grid and Level in Settings > Camera.
• Corner shot: A photo taken from a corner or doorway looking diagonally across the room, which shows the most floor and two walls at once and is the usual framing for living rooms, bedrooms and open plans. HomeJab suggests keeping the camera 18 inches from the corner and at least three feet from walls and furniture, so the nearest surfaces don't stretch (how to photograph small rooms).
• Stitching (panorama): Joining several overlapping frames taken from one spot into one wider photo. For interiors, keep the phone level and turn the phone, not your body, between frames so they line up; nothing is added or removed, and California's AB 723 doesn't name stitching.
• ProRAW (RAW): Apple's RAW format on Pro iPhones from the iPhone 12 Pro on, which keeps more data for adjusting exposure, color and white balance afterwards, at about 25 MB per 12 MP file and 75 MB at 48 MP. Listing portals expect JPEG, so every ProRAW file has to be edited and exported before upload.

Light and exposure

• Bracketing: Taking several shots of the same scene at different exposures, typically one normal, one or more darker and one or more brighter, so they can be combined later. HomeJab suggests three RAW frames at 0, −2 and +2 stops for rooms with a wide range of light; a tripod keeps the frames aligned.
• HDR (high dynamic range): A photo blended from bracketed exposures so that both the view through a window and the dark corners of the room keep detail, because a single exposure can't hold that range of light. iPhones do it automatically: Apple says the camera takes several photos at different exposures and blends them, so leave HDR on for interiors.
• Exposure fusion: A way of blending bracketed frames straight into a normal, viewable photo by keeping the best-exposed parts of each, without first building a high-bit-depth HDR file and tone-mapping it. Strictly it isn't HDR, since no HDR image is ever made, but the result does the same job on screen.
• Window pull: A separate exposure made for the view outside, blended into the interior photo so the window shows the view instead of a white rectangle. HomeJab describes exposing for the outdoor scene even if the interior turns dark; AI editors such as Autoenhance.ai now offer window pulls as an automated step.
• Flambient (flash and ambient blend): A professional lighting method that layers a no-flash ambient exposure, a bounced-flash exposure that restores the true color of walls and objects, and usually a window pull, then blends them by hand in an editor. PhotoUp and HomeJab both describe the ambient frame as the base layer.
• White balance: The setting or correction that makes white surfaces look white under a given light, so warm bulbs don't turn the walls yellow and daylight doesn't turn them blue. It is exempt under California's AB 723 and needs no label at most MLSs; MLSListings is the exception, asking for enhancements such as color enhancement to be disclosed in the public remarks.
• Color cast: An unwanted tint over part or all of a photo, most often from mixing warm and cool bulbs in one room. Use one bulb color per room and switch off lamps that tint the walls; in our measurement of 200 professional photos, walls came out neutral to a touch warm (CIELAB a* 0, b* +3).
• Twilight photo: An exterior taken just after sunset, in the blue hour, when the sun is about 4 to 8 degrees below the horizon, the sky is deep blue and every light in the house is on; at New York's latitude in March that window lasts about 20 minutes. A real twilight set from a photographer costs $200 to $750 (PhotoUp) (twilight photos with an iPhone).

Editing and retouching

• Vertical correction (perspective correction): Straightening, in editing, the lines that should be vertical, such as walls, door frames and cabinets, by warping the image. A big correction crops away the edges of the frame, so it works best on a photo taken nearly level; straightening is one of the edits California's AB 723 exempts.
• Converging verticals (keystoning): Vertical lines that lean toward each other because the camera was tilted up or down, so the room seems to tip; the name comes from the keystone shape a rectangle turns into. Photography for Real Estate lists converging verticals among the effects that distract viewers of an interior photo.
• Two-point perspective: A view with two vanishing points: with the camera level and aimed diagonally across a room, horizontal lines recede toward two points while vertical lines stay vertical. Tilt the camera and the verticals gain a third vanishing point, which is what converging verticals are.
• Lens correction: Software that removes the bowing of straight lines a lens causes near the frame edges (barrel distortion). Apple's Lens Correction setting does this for Ultra Wide photos and is on by default, but no correction undoes the stretching of objects near the edges, which comes from the wide view itself.
• Sky replacement: Swapping a gray or blank sky for a blue one in editing. It made up 69% of the altered images in Coraly's review of just under 40,000 portal listing photos; AB 723 covers elements visible from the property, so in California treat a new sky as an alteration, while Metro MLS needs no watermark for a realistic one.
• Day to dusk (virtual twilight): An edit that turns a daytime exterior into a twilight one by darkening it, lighting the windows and replacing the sky, sold for a few dollars an image (BoxBrownie, PhotoUp) up to about $40 (HomeJab). It adds and changes elements, so under California's AB 723 it is a digitally altered image that needs a label and a link to the original.
• Item removal (digital decluttering): Erasing loose objects such as cables, towels, bins or a car from a photo. Metro MLS and SFARMLS treat decluttering as needing no disclosure and ARMLS treats it as digitally altered, while California's AB 723 covers any edit that removes elements in the image, so label these photos in California (MLS photo rules by MLS).

Virtual staging and AI

• Virtual staging: Digital furniture and décor added to a photo of a real room, usually an empty one. It costs from under $1 a photo with AI tools to about $16 to $69 a photo from human designers, and most MLSs that address it require a disclosure, 14 of the 22 we checked (virtual staging cost).
• Virtual defurnishing (virtual emptying): Removing the existing furniture from a photo to show the room empty: its size, floor and light. It removes elements in the image, so it is a digitally altered image under California's AB 723, and CRMLS names it as an example (virtual staging vs. an empty room).
• AI photo editing: Editing with an image model, from a one-click enhance button to redrawing a whole room from a prompt; models can "hallucinate" details such as an extra window or wall, so check every fixed feature against the original. The tool doesn't change the rules: CRMLS says AI-altered images count as digitally altered images (AI photo editing and MLS rules).
• Fixed features: The parts of a property that stay with it, such as walls, floors, windows, cabinetry, fixtures, paint, landscaping and the view. MLS rules allow staging with furniture and décor but ban changing fixed features in a photo; CRMLS allows it only if the home will really be improved to match by closing.

Listing and MLS rules

• MLS (multiple listing service): The database local brokers use to share their listings, photos included, with other brokers and, through data feeds, with websites and portals. There is no single national MLS, and each one sets its own photo rules (MLS photo rules by MLS).
• IDX (Internet Data Exchange): The MLS policy that lets brokers show each other's listings, photos included, on their own websites and apps. NAR's policy describes it as giving MLS participants the ability to authorize limited electronic display of their listings by other participants.
• Syndication: The MLS sending its listings to third-party portals such as Zillow, Realtor.com, Redfin and Homes.com. The portals mostly show what the feed sends, so a listing photo is fixed in the MLS, not on the portal, and Zillow says the change can take up to 24 hours to appear (update listing photos on Zillow and Redfin).
• Primary photo (hero shot): The first photo of a listing, the one shown in search results. Stellar, RMLS and MRED want an exterior in that slot, and Metro MLS requires the main photo to be an unaltered original.
• Branding rule: The MLS ban on logos, brokerage names, contact details and superimposed text on listing photos, published by 20 of the 22 MLSs we checked. The only marks usually allowed are the MLS's own watermark or the altered-photo watermark that Metro MLS, ARMLS, RMLS and SFARMLS require.
• Coming Soon: A listing status some MLSs offer for a home that is marketed before it becomes active. Photo rules can differ for it: Bright MLS, which wants the rest of the photos within 72 hours of listing entry, waives that deadline for Coming Soon listings.
• Digitally altered image: Under California's AB 723, a listing image made by or for an agent that has been altered with editing software or AI to add, remove or change elements in it, such as furniture, fixtures, paint, landscaping or the view. Lighting, exposure, white balance, color correction, sharpening, angle, straightening and cropping are exempt when they don't change how the property is represented. CRMLS accepts labels such as "Digitally Altered," "Virtually Staged" or "AI Altered" in the photo's text field, with the unaltered original immediately before or after the altered photo.
• AB 723: The California law, in force since January 1, 2026, that requires an agent who uses a digitally altered image to market a home for sale to say so on or next to the image and to link, or give a QR code, to the original. It added section 10140.8 to the Business and Professions Code, and a willful violation of the Real Estate Law is a misdemeanor with a fine of up to $10,000 (AB 723 guide).
• Listing photo size: Landscape JPEGs at least 2048 pixels wide and under 10 MB clear every major portal's minimum: Zillow suggests 1536 × 1152, Airbnb asks for 1200 × 800 and Bright MLS 1024 × 768. Any iPhone 12 or newer shoots 4032 × 3024, and the free listing photo resizer makes the smaller copies in your browser (photo size requirements).
• Aspect ratio (3:2 and 4:3): The shape of a photo, width to height. The iPhone shoots 4:3 by default, 3:2 is the full-frame camera shape HomeJab recommends for MLS photos, and a 4:3 frame can be cropped to 3:2 but not the other way round; every portal we checked accepts 4:3 landscape.
• HEIC (HEIF): The iPhone's default photo format, which Apple says takes less space than JPEG at the same visual quality. No major listing portal lists HEIC among its accepted formats, so choose Settings > Camera > Formats > Most Compatible to save JPEGs, or export JPEGs before uploading.
• JPEG compression: The way a JPEG file is made smaller by discarding fine detail; every re-save, or a trip through a messaging app, compresses it again and softens it. In our measurement the iPhone's own JPEG compression cost at most 3.8% of the finest detail, so upload the file the camera or the editor wrote.
• EXIF metadata: The data stored inside a photo file: camera, lens, focal length, exposure settings, date, orientation and, when location is on, GPS coordinates. Zillow blames sideways photos on missing or wrong EXIF orientation data, and Apple's Photos share sheet has an Options switch to leave the location out.

Video and tours

• Walkthrough video: A video that follows one route through a home to show how the rooms connect. Zillow Showcase allows up to 120 seconds, and in NAR's 2025 survey 29% of buyers who searched online rated videos very useful, against 83% for photos (walkthrough video with an iPhone).
• Unbranded virtual tour: A tour or video with no agent or brokerage names, logos, links or contact details, which MLS virtual tour fields usually require; MLS Now bans branding even in the YouTube description. In NAR's 2025 survey, 41% of buyers who searched online rated virtual tours very useful.
• 3D tour (digital twin): An interactive model of a home, captured at many scan points with a phone, a 360° camera or a dedicated 3D camera, that a buyer moves through room by room. One Matterport service provider lists $350 to $1,000 for a residential tour plus $20 a month to host it (photos, video or a 3D tour).
• Matterport: The best-known 3D tour platform, owned by CoStar Group since February 2025. It builds interactive tours, floor plans and room dimensions from a phone, a 360° camera or its own Pro2 and Pro3 cameras, and hosting tours takes a paid subscription; Zillow 3D Home is the free alternative for Zillow listings.
• Floor plan: A drawing of a home's layout, usually with room dimensions. In NAR's 2025 survey 57% of buyers who searched online rated floor plans very useful, more than virtual tours (41%), and a standalone 2D floor plan has a median price of $205 (PropPhoto).
• Drone photography (Part 107): Aerial photos or video of a property. Flying a drone commercially in the US requires an FAA Remote Pilot Certificate under Part 107: the pilot must be at least 16, pass the initial aeronautical knowledge exam and complete online recurrent training every 24 calendar months; drone add-ons cost about $50 to $250 (PhotoUp).

Short-term rentals

• Airbnb Pro Photo program: Airbnb's own professional photography offer: 15 to 25 retouched photos with no upfront payment, the cost deducted from future payouts once the new photos are live. It depends on photographers being available in your market, and the price is shown in your host account (Airbnb photography cost).
• Photo tour (Airbnb): The room-by-room layout of an Airbnb listing's photos, sorted into rooms automatically by AI and editable by the host. Each room needs at least one photo to appear, and Airbnb says changes can take up to 30 minutes to show (Airbnb photo upload problems).
• Cover photo: The first photo of a rental listing, the one guests see in search; Airbnb gives the first five photos the most prominent place and crops search results to squares. Keep the main subject in the middle of a landscape frame, and change it under Photo tour > All photos > Make cover photo.
• Photo verification (Airbnb): Airbnb's check that a listing's photos are accurate: the host takes new photos in the Airbnb app at the property, from the same perspective, and camera-roll photos can't be submitted. Airbnb also asks hosts to remove photos where AI or other editing hid flaws or damage or added things that aren't there, CTV News reported in July 2026 (Airbnb photos vs. reality).
