I need to prepare some photos for an e-ink display. The display is 1-bit. Each pixel is either 100% black or 100% white - there is no gray.
I know that I can change the mode of my photos in Photoshop to bitmap, and it will present a number of options as to how the dithering and noise are handled. But this process is destructive.
Is there a non-destructive way to simulate this in Photoshop?
I tried using the Halftone filter in Grayscale mode, but this makes circles instead of pixels, and doesn't have any dithering options.
I can't be the first person to need this - am I doing it wrong?
Adding some examples below.
I'm using an e-ink display from Waveshare. It's 800x400 at approx 49 pixels/cm, 1-bit bitmap. So I've set up my Photoshop document like this:
I want to be able to try out different 1-bit bitmap "looks", without destroying the original layer:
But a diffusion dither, gives a different look:
I would like to simulate all of these different looks in a grayscale document, without having to destructively edit my image each time.
I can use the Halftone Pattern filter on my original image, but it doesn't offer the same settings as the 1 bit bitmap conversion, and looks different:
