Another way to approach dithering is to analyse the input image in order to make informed decisions about how best to perturb pixel values prior to quantisation. Error-diffusion dithering does this by sequentially taking the quantisation error for the current pixel (the difference between the input value and the quantised value) and distributing it to surrounding pixels in variable proportions according to a diffusion kernel . The result is that input pixel values are perturbed just enough to compensate for the error introduced by previous pixels.
Google says Nano Banana 2 can maintain character resemblance for up to five characters in a single workflow, which could be especially valuable if you’re using it to create storyboards or visual stories. It can follow precise instructions for complex requests, as well, and can generate input with up to 4K in resolution with richer textures and sharper details than its predecessors could.
