Usually, yes—but only to a point. Most real estate photos are made with rectilinear wide-angle lenses, not fisheyes. Rectilinear lenses keep straight lines straight, which is why they’re common for interiors, but they stretch objects and faces near the frame edges because they’re trying to map a very wide 3D view onto a flat image.

You can partially correct the look in post-processing. Tools like Photoshop’s Adaptive Wide Angle or Lightroom’s Geometry/Upright controls can make a room or subjects look more natural. But there’s a trade-off: if you reduce the stretched look of people or objects, straight architectural lines may start to curve or otherwise look less natural. If you preserve straight walls and door frames, edge subjects may still look distorted.

So the answer is: you can improve it, but you can’t perfectly “undo” all wide-angle perspective effects from a single flat photo. Some compromise is unavoidable when projecting 3D space onto 2D.
