What it checks
- Size. Compared with Zillow's suggested 1536 x 1152 pixels and Airbnb's 1024 x 683 minimum and 1200 x 800 suggestion. Your MLS may have its own numbers, so check those too. More in the Zillow photo requirements guide and the Airbnb guide.
- Shape. Vertical photos get cropped or boxed in on most listing sites. Shoot horizontal.
- Brightness. The average brightness of the whole photo. Dim photos are the most common problem I see from phone shots, and the first thing buyers scroll past.
- Crushed shadows and blown highlights. How much of the photo is near-black or pure white. Pure white usually means a window lost its view. See how to handle bright windows.
- Color cast. Whether the white and gray surfaces (walls, ceilings, trim) lean yellow-orange, which usually means indoor bulbs, or blue, which usually means shade or an overcast day.
- File size. Some sites cap uploads around 10 MB. The free MLS photo resizer shrinks big files without uploading them.
Checking vertical lines
Tick Show a grid and look at door frames, cabinet edges and wall corners. If they lean against the grid lines, the phone was tilted up or down. Hold it level at about chest height and step back instead of tilting. My iPhone listing photo guide covers this in more detail.
What it doesn't do
- It doesn't judge composition or clutter. A photo can pass every check and still show a messy counter. Use the listing photo prep checklist for that.
- It doesn't change your photos. It only measures them.
- The thresholds are rules of thumb from shooting homes for almost 20 years, not an MLS rule. A moody twilight shot can be dark on purpose.
Is my photo private?
Yes. Once the page loads, all the measuring happens in your browser. Your photos aren't sent to Listing Camera or anyone else, and the page keeps working if you go offline.
