I don’t know how you’re scanning these, or how you’re adjusting the images, but you really should let through more shades of gray, rather than equalizing everything to binary black/white. Some of the texts are impossible to read and lots of details are lost.
Yeah, exactly.
Well about my scanner that somehow it settled to have that effect and trust me. I never put that effect when I scan.
I gotta check the settings before I could upload the fixed version.
