What is monochrome dithering?

Dithering is a technique used to create the illusion of color depth in images with a limited color palette. In monochrome conversion, it helps represent gradients and shades of gray using only black and white pixels, resulting in a more detailed and visually pleasing image.

Which dithering algorithm should I use?

Floyd-Steinberg is the most common and generally provides good results for most images. Atkinson tends to preserve more detail but can result in higher contrast. Experiment with different algorithms to see which one best suits your specific image.
