Difference Cloud + Threshold Size
Hello to everyone!
I'm new here, as you can see from my date of registration, and I'm new to cartography.
Apologies if my thread is not for here.
Today, I decided to make a map of my own. The thing is, I need it to be enormous.
Its size is 41667 x 41667 with a resolution of 300. I'm following this Photoshop tutorial. Unfortunately, when I use the Difference Cloud + Threshold thing-y + copy/paste the part of coast, the size, compared to my map is quite small and I'll probably need 1000 layers to cover all of my island coasts this way. I was wondering if there's a way to make the parts that I'll be copy/pasting bigger, but with the same resolution. I tried making the "New File" from the first tutorial 30000 x 30000 with resolution 300, but my laptop can't seem to handle it. Any ideas to what I can do about this?
