Colour negative conversion throws an error

Thanks a lot! I'll try your fix and will let you know how I get on 😄

Sorry for such a late reply!
That's a strange issue I haven't seen before... Can you confirm for me that you can also run imagemagick in the terminal?

[sjaakluthart]

Yes I can run imagemagick in my terminal

Hey, I finally figured this issue out. Something seems to have broken negfix8 in the newer imagemagick versions, meaning you have to downgrade to an older version for it to work.
Assuming you already have imagemagick installed downgrade to v6 like this:

1. run brew install imagemagick@6
2. run brew link --overwrite imagemagick@6
3. You'll probably get a suggestion by brew to run something like echo 'export PATH="/usr/local/opt/imagemagick@6/bin:$PATH"' >> ~/.zshrc

That should fix any issues like the one you had where negfix8 wouldn't work.
If you're using the IR version of my script you'll need to download the latest release, since I had to make some changes to make things work with imagemagick@6.

Give it a go and let me know if it works for you!
