Why do my photos look fisheyed or have extreme wide-angle distortion?

AutoHDR applies lens distortion correction automatically to RAW uploads when your lens is in our database. If you're seeing extreme distortion that didn't get corrected — fisheye curves, very wide-angle warping — the most likely cause is that your specific lens profile isn't in our database yet.

Workaround

Open your RAW files in Lightroom or Capture One, enable Lens Corrections in the export panel (Lightroom: 'Enable Profile Corrections' under Lens Corrections), and export as JPEG. The exported JPEGs will have correction baked in and AutoHDR processes them as-is.

If the warping is from tilt or perspective

The same export workflow applies — Lightroom's Geometry/Upright tool can correct that before export.
