I was wondering if there is any way to save images in a black/white TIFF encoding directly (such as CCITT 3 or 4).
I've got a bunch of B/W TIFF images compressed with CCITT 4. I can open and edit them fine in Paint.Net, but when I save them they are converted to full R/G/B/A images using LZW compression. This results in images going from ~100kb to roughly 1MB.
