Strange halo when exporting

Recommended Posts

Hi,

 

when exporting an image I made I get some strange artifacts. Relevant section here:

image.png.80694315b9a0e1885a65c881cac5612f.png

 

That's 16bpp image exported to 8bpp png, different methods of resizing.
Exported with bicubic:

Exported with Lanczos sep:

Exported with Lanczos non-sep:

Can provide you with the image if need be.

Ok, I will send this for both bug reports. Please send me a upload link.

Hi, sorry, I was at work and missed that link.

I tested w/o High Pass and you can still see the halo on that layer in export.

I vaguely remember that similar issue was visible in another image I had a long time ago.

 

File uploaded, it for this here, and this linked bug report:

@Chris B, were you able to reproduce this?

Hey TEcHNOpls,

Unfortunately not, no. If I zoom in on the same area I can't see anything like what is pictured in your screenshot :( Do you know which layer it is on? 

This is a screenshot with all layers on (apart from the top Curves Adjustment):

@Chris B: Try exporting that image, esp. with Lanczos non-separate. The issue should be visible then. Also scale down (in my example, it's 2048px on longer edge) and into png file.

Edit: attached file has my export preset in it (in export persona), as I cannot send you the preset itself (no export/save option).
