Weird issues with hdr
2023-11-22 22:05:49
So far the HDR editing looks amazing. The issue I’m having is when the images are scaled down to SDR they look washed out with blotches of muted color and contrast. Unlike when I use apples photo editor which look fine when converted to sdr. The overall feel and contrast of the sdr mostly matches what the HDR was, just without the pop. Maybe the scale is different when tone mapping to see compared to what Apple is doing. Maybe add an add a sdr preview button so we can preview what an image will look like when converted to sdr. Also the previews look bad in the photos app, same washed out issue. Doesn’t happen if I export a hdr jpeg.

I don't think the thumbnails are ever rendered in HDR in Photos. However if you open the picture by double-clicking it the HDR version should show instead of the low quality JPEG used as thumbnail.

I see that the regular image looks fine when opened, just the previews are washed out if saved as the default, or as HDR Heif. But if i export to HDR, jpeg, they look fine. just an observation

I have the same issue.
Even if I open an HDR modified (from Photomator) file in Photos, the full effect doesn't show until I zoom in a bit then it seems to activate?

Is there a fix to this? The photos look substantially better in Pixelmator Pro and not in Preview. Zooming in and out in preview flashes the full effect for a second.

As far as I know Apple Preview app does not support HDR at all, so it renders it poorly. Apple should add HDR to that app but has not. To view the photo in HDR you must use the Photos app.

Looking into this by looking at the meta data of the images, I think the reason is the way Pixelmator is handling hdr. Apple uses a regular sdr photo and overlays a hdr glow brightness map layer on top that. Which is like a black and white image that tells photos and whatnot to “glow” in certain areas.. But when displayed on a sdr display, they just ignore the hdr layer map and shows the sdr image.
What pixelmater is doing is more akin to hdr video. The whole image is tone mapped to hdr. There is no sdr layer. So when displayed on a sdr display, or convert to sdr, it takes anything above sdr brightness and just overexposes. It doesn’t even try to properly tone map it.
