How to Fix a Blurry Panorama After Upload
Troubleshoot a blurry panorama upload by checking source focus, export size, compression, scaling, and viewer preview.
Locate the loss of detail
Compare the original source, stitched master, exported file, and uploaded preview at the same on-screen scale. Blur in every frame usually begins with focus, motion, or camera shake; blur only after export usually begins with resizing or compression.
Download the published file when the service permits it. A soft thumbnail may be temporary, while the full-resolution view can remain sharp.
- Uniform softness: check focus, shutter speed, and source resolution.
- Only seam areas soft: inspect blending and source frame alignment.
- Blocky or smeared detail: check JPEG quality and repeated exports.
Improve the source and stitch
Use the original files and focus once before the sequence begins. Lock focus, exposure, and white balance where the camera permits. Use a shutter speed that freezes hand movement and a stable support when the scene or light requires it.
Avoid enlarging a small panorama to meet an upload dimension. Upscaling changes pixel count, not captured detail. If a few frames are soft, replace them from the capture sequence rather than applying sharpening to the whole panorama.
Export once at an appropriate size
Export the stitch from the master project at the largest practical size accepted by the destination. Resize in one controlled step, use the format recommended by the service, and avoid repeatedly opening and saving a compressed JPEG.
Apply modest output sharpening after resizing, not aggressive sharpening before it. Halos around straight lines are a sign that the sharpening step is too strong.
- Keep a lossless or layered master.
- Choose quality high enough to preserve fine texture.
- Review the export at 100 percent before uploading.
- Do not confuse a viewer's low-detail preview with the original upload.
Common mistakes and a final checklist
A frequent mistake is judging a zoomed-in viewer preview on a high-density display, then sharpening until artifacts appear. Check the actual downloaded file and the final display context before changing the source.
Use this short checklist:
- Compare source, master, export, and upload at equal scale.
- Replace soft frames and verify focus before stitching.
- Resize only once, then apply restrained output sharpening.
- Use the service's supported dimensions and format.
- Confirm whether the viewer is showing a preview.
