So there are a couple of iOS apps that "scan" documents and automatically do some processing to make the image look like a quality scan from a real scanner.
When I'm trying this on the Mac with pictures from a DSLR manually with Photoshop the results are usually not as good as what these apps achieve.
Therefore I'm looking for either a Mac app or instructions for Photoshop on how to achieve this. Or maybe even an Automator script.
Just to be clear: I do not need OCR!
You can use ScanTailor.
Scan Tailor is an interactive post-processing tool for scanned pages. It performs operations such as page splitting, deskewing, adding/removing borders, and others. You give it raw scans, and you get pages ready to be printed or assembled into a PDF or DJVU file.
The program is developed for Windows, GNU / Linux, and other Unix-like systems such as Mac OS X. See Installation . You might need to build it from source though.
I found this Photoshop tutorial that might help. It's a semi-broken webpage without the images. https://tricky-photoshop.com/make-document-looks-like-scanned-copy-photoshop There's a video there that was useful https://www.youtube.com/watch?v=uiwvTHLJ0gc&feature=emb_logo Essentially, it looks like they crop, level to get rid of gray, then increase contrast before running it all through a high pass filter. I used it with a color photo (so I skipped black and white) and it looked pretty good. I had the same question and am not a photoshop expert. But the instructions worked for me.
