Affinity Photo 1.8.2.620 Defringe

[tonyk11]

Hey all.  Hope you're doing well and staying healthy.  I'm trying to run the defringe function on a photo I'm editing.  The photo is from a Nikon camera.  I perform the defringe function and get the fringes removed correctly, but when I merge layers, the fringes automatically return.  Any ideas?  Not sure if I'm doing something wrong.  Thanks for the help.

Hi tonyk11,

My sincerest apologies for the delayed response!

Could you please confirm for me, what layers are you merging, following the defringe operation? Does this happen with any document, or only in the 1 example you're referring to?
Can you possibly provide a copy of this document?

Many thanks in advance!

Hey Dan C.  No problem.  Generally, I'm merging two layers that are comprised of a working layer and a duplicate of the working layer.  The same thing happens when I'm using a Sharpen layer (usually done with a high pass or an unsharp mask).  I have the working layer and the sharpen layer on top, using it to mask in sharpening where I want it.  When I merge the layers, the sharpening disappears, as does the defringing.  It does happen with any document I'm working on, which are generally photos that are developed NEF RAW files.  Any help is appreciated.

Have a nice day.

@tonyk11 I have been off for a few weeks and not checking the forums, so my apologies for not responding here until now.

Could you please provide me 2 sample files, one before you complete the merge operations, and one after merging?

These can both be uploaded to the below link for me:

It's likely the adjustments are affecting more than one layer, then when merging they only affect the layer they've been merged with, providing different visual results, but I'll need your documents to confirm this. 

Many thanks in advance

Merge Selected command in AP 1.8.3 (and the current 1.8.4 beta on macOS) merges layers into the first selected instead of the lowest selected, so select the lowest layer first, then the upper one, and then do the Merge Selected. Alternatively, just right-click the upper layer in Layers panel and pick Merge Down.

Hey Dan C and Anon.  I appreciate the replies.  I will try to provide some files for you very soon, and I will also try out the "merge down" command and see if that fixes my issue.  Thank for the help.

And don't worry about the delay.  None of this is world-shaking stuff I'm working on here.
