Exported .hdr files are black in Preview app.


Recommended Posts

When exporting .hdr files and opening them in Preview, the image is black. When viewing the same file in Quick Look, the image is rendered properly. 

Also, on Preview, when panning and scaling the .hdr file, the images are momentarily rendered properly.

Since the image is rendered properly in Quick Look, but not Preview, this is likely a bug.

Edit: this only occurs with about half of the .hdr files. For comparison, the bug occurs with Hawaii2022_34, but not Hawaii2022_18. Both attached.

MacOS Ventura 13.0.1.

Hey devon7y,

That's odd - I'm not entirely sure what's going wrong here. I'm not sure if it's because the file is encoded as half float. Is there a reason you're doing HDR? My solution would be to use EXR which can encode to fill/half float and will display in everything.
