Title:
possible 32bit TIFF mishandling
Status in Hugin:
Incomplete
Bug description:
I'm testing an HDR workflow with 32bit HDR tiff files (BT.2020 Linear) and have noticed 2 issues:
1) The thumbnails on the Photos tab have different gamma/color mapping to the previews in the Masks and Control points (I suspect that these three tabs are not using the same gamma curve).
2) cpfind returns 0 control points.
running on:
M1 Mac, macOS Sequoia 15.1.1
cpfind 2024.0.1.ead3af10a01a built by Author name
