Rescuing thousands of images from a blemished life

Hi,

I sincerely apologize for this - I don’t want to take up anyone’s time, so please just shoot me to another page rather than explaining, if you see what’s wrong here.

If i take this picture (terrible though it is):

…and run it through:
gmic {image name} +_fx_remove_scratches 72,2,4,3

I get no discernable change.

I then opened gimp to see if I could see what the output after the first threshold step was, and it doesn’t matter what parameters I input, I can’t get any “flecks” in the Threshold output, so I suspect that’s why it’s not working.

Can you tell me why that would be? I’ve looked here https://sourceforge.net/p/gmic/wiki/Tips%20and%20curiosities/#6-the-threshold-command and seen that if there is no normalise command, you get a blank screen.

When I look in the gmic config for the “routine” I don’t see a normalise statement after the threshold statement. Something tells me though, that because @David_Tschumperle wrote it, it’s probably not needed. :slight_smile:

You must cringe at newb comments like this, but I’ve done a few hours of googling trying to find the answer and I’m none-the-wiser. :frowning: Sorry… PEBKAC, I s’pose. :slight_smile:

Thanks again.
