mntn.xyz talks about dithering:
> It seems that dithering is undergoing a renaissance on Gemini. Not only does it introduce a pleasant retro aesthetic, but for images with smaller dimensions, dithering with a reduced palette can both save bandwidth and make content more accessible to old devices.
I decided to give it a try, with a couple twists.
I'm using Python to dither the images:
from PIL import Image
input_ = Image.open('image.jpg')
output = input_.quantize(
colors=8,
dither=Image.FLOYDSTEINBERG,
kmeans=1,
)
On my blog I'm blending the dithered images using CSS, depending on the choice of a light or dark theme:
@media (prefers-color-scheme: dark) {
img {
mix-blend-mode: screen;
}
}
@media (prefers-color-scheme: light) {
img {
mix-blend-mode: multiply;
}
}
