sorry I love stalking activity. I think you’re talking about “image dithering”. There are tools online and tutorials to help recreate in ps or gimp
in photoshop you can "dither" your image by clicking image > mode > indexed colors. my settings are palette: local (selective), colors: 216, forced: web, and dither: pattern.
Thank you!! I am so excited to start using it! :-D I'm so devoted to the Hobonichi though, I can't see myself ever straying too long lol
You can view the "my pets" page here: https://petdiary.neocities.org/mypets.html
And you can view the memorial page here: https://petdiary.neocities.org/petmemorial.html
Outside of the frames of course... You can view them as intended by clicking the about page > my pets > scroll to heart image for memorial
