Obv. gonna keep only this quality greyscale and further optimize it
It's interesting to note that the cover (first page) is not real resolution as it got sampled down badly and show artifacts While the last page (pag 44) is better, doesnt have artifacts but its cropped probably from the original, comparing the two and doing some math it seems the original is around 6000-6300px (H) which is the usual resolution but for some reason even the raws dont have this file
