My suspicion is that you didn't handle the gamma correctly as mentioned in another comment.

- Matumio 9y agoIndeed, the dithered image looks way too bright. It should be converted from sRGB gamma to linear light before dithering to black/white. Also, will need more than 8bits per channel if you hold the linear image as an intermediate result, otherwise you get posterization in the dark areas before the dithering even starts.
