Denoising suggestions in Affinity Photo

[nickbatz]

These little shizzles, obviously zoomed way in here, may or may not be visible in the print. But it's going to be very big (about 3-1/2' x 6'), and even though I make smaller test prints on my "small" sheet printer, I don't want to leave this to the gods.

I know how to fix this in Affinity Photo manually (there are several ways), but does anyone have any ideas about automating some of it? Are there any filters, etc.? These artifacts are pretty widespread on this picture.

This is after processing it in Gigapixel AI's denoising algorithm, by the way.

TIA

If you mean the small white dots then the Dust & Scratches filter will work for them

It's very sensitive so use the minimal amount

You many want to apply a sharpen filter afterwards to restore previous sharpness level if affected

Well, I decided against using the filter (because I don't want to screw with the texture, and sharpening filters tend to do that).

The things we do for art.

The curved line with bigger dots is something else, but each one of those little ones is using the clone brush. Oy!

Weird, I thought I thanked you for the suggestion yesterday - which is to say that I wrote a reply but must have screwed up on my iPhone.

So thanks today.

I decided not to use a filter, because even the best sharpening algorithms tend not to work well for what I do when I use them on all the layers (I have dozens in my pictures). But I wasn't aware of that filter, and I'm sure I'll use it at some point.
