Testing dithering and color reduction

Published 2021-06-18 17:36:52

Hello!

I’m trying to convert images so that they are lighter. I got the idea from Low-Tech Magazine and got some help and information from a good guy.

Using ImageMagick:

convert input.jpg -set colorspace Gray -ordered-dither o8x8 -colors 2 output.gif

From this image:

Original

We get this one:

Grayscale + Dither + Color reduction

From 72KB to 16KB. Looks a lot like the gameboy camera actually. There are other dithering algorithms, but for this photo the ordered-dither gave the best picture.

And now the new reduced image with a link to the “HD” one!
