Thanks, Mike!

Thanks, Kevin!

Was thinking about this some more, and you could try Aseprite to see what it could do. It’s built for working with limited palettes and has dithering tools.

Posterize may produce some odd results in areas with noise. So you might have to preview and cancel and adjust your other steps and check again. You could also try a gradient map instead. And I see others have suggested switching to indexed colour and building a custom colour table. :)

What I would try:
1) use a Black & White adjustment layer to get the tones close to what you want
2) use Levels and darken the darks and brighten the brights, adjust the grey centre to get closer to a B&W image
3) use Posterize with 3 levels (might have to go back to 1&2 to adjust and repeat)

Would love to hear about it afterwards! It's one I think about going to every year, but have never actually gone. :)

omg I miss Montreal. hope you have a great time at MIGS!

Hello, yes, do you ship to Ontario?

Haha deep cut!

The best costumes are the ones you have to explain to everyone, and then they eventually go, “Ohhh. Ok.”

I was explaining to my kids about how restaurants used to have smoking and non-smoking sections. 13yo said, "That's stupid. Didn't the smoke just go everywhere?" It sure did!

E.g.
"Go Jays!"
Go Jays!
"Yeah, can I get a large double-double to go, please?"
Here you are. Go Jays!
"Go Jays!"

Of course I'm only kidding. I friggin' LOVE spreadsheets! (Seriously, they're so much fun)
