minus-squareChaoticNeutralCzechlinkfedilinkEnglisharrow-up1·2 months agoThe dithering makes it look like a reduced palette image, then why does it have 144 044 unique colors among 986 420 pixels? What software even produces this?
minus-squareChaoticNeutralCzechlinkfedilinkEnglisharrow-up1·edit-22 months agoI was wondering why it’s 2 megabytes. Both a low-noise full-color image (as a JPEG) and a palettized image (as a PNG) would compress way better. So how did you make it? Reduced the palette and added noise? It would be an imperceptible but very optimizing change to reduce the palette to 256 colors afterwards.

thank you for inspecting my images
