Upload an image! If the image is already Black and White Posterized, that should be detected automatically. If not, please just upload the original version of your color photo instead.
You can click on "Upload File" at any point to restart the process.
If you run into any issues/bugs, feel free to just refresh the page and try again.
IMPORTANT NOTE: If the image you upload is high resolution (like >1k by 1k pixels) the generation might take some time, just be patient.

Interesting Note: There is some weirdness going on with the physics of color averaging which might account for some of the images looking funky.
I tried to compensate my code for it in some areas but I don't know if I covered everything. Here is a great youtube video explaining this phenomenon
