How to completely fix tripod shadows and the nadir in a 360 real estate virtual tour?
The nadir (bottom blind spot showing the tripod) is fixed through several methods: automated AI nadir patching tools in platforms like Matterport handle it automatically. For manual workflows, use Photoshop's clone stamp on the equirectangular projection, or capture an extra handheld shot looking down from each position and composite it in. Some photographers also use nadir caps — pre-made branded images that cover the tripod position.
Why are the vertical lines converging in my real estate 360 panoramic interior photos?
Converging verticals in 360 panoramas are caused by lens distortion and imprecise leveling of the camera during capture. The 360 camera must be perfectly level (use a leveling base or tripod with bubble level). In post-processing, apply tilt-shift corrections in PTGui or your stitching software. Some cameras offer in-camera horizon leveling that corrects minor misalignment automatically during capture.
How to correct lighting exposure problems between bright windows and dark rooms in 360 photos?
Use HDR (High Dynamic Range) bracketing: capture multiple exposures at each position (typically 3–7 brackets spanning the full dynamic range) and merge them in software. Most professional 360 cameras offer automatic HDR bracketing. In post-processing, tone-map the HDR image to balance bright window light with dark interior shadows. Shooting during overcast conditions or twilight also naturally reduces the dynamic range challenge.
