[Fixed] Halos in a 32bit document - affinity photo 1.7.0.184

Recommended Posts

Hi there,

I'm getting some halo on a 32bit hdr document with affinity-photo-customer-beta-1.7.0.184

This is the original file:

I wanted to blur and tweak the color of the two hotspots:

It looks fine in Affinity Photo.

Then, when imported in Cinema 4D and rendered, I get this:

Indeed, checking the HDR in Photoshop reveals some unwanted halos which are not visible in Affinity Photo:

Nonetheless, exporting the images as EXR rather than HDR seems to get rid of the halos.

Got it—thanks! 

I've exported it as HDR and opened it in a few apps and I'm seeing the issue across them all so something isn't right :56_anguished: I'll let the developers take a look.

Hey verysame,

Is there a reason you need it in HDR format as opposed to EXR? It's fine if you do, I've just been asked to ask you :) 

There's clearly an issue but EXR should be a viable workaround for now...

Thank you for checking, Chris!

Yes, the EXR was working fine, but I ended up exporting the HDR from Photoshop. I'm not in front of my computer right now, I might be wrong, but I think the EXR was heavier.

Besides, the client asked HDR maps, so unfortunately in this case I don't have much room for workarounds otherwise I could have used the EXR.

I'll try to recreate the steps in order to get a similar result and this time I'll make sure I save the file with all the layers :D

Hi,

I just saw similar issues when I have 16bit image. The halos disappear when converting image to 8bit.
