impact Posted November 27, 2021 Posted November 27, 2021 Hello, is this possible to fix this photos with Affinity Photo to be easier for reading and printing ( especially that ). Main goals: Make background paper white Make text contrast Remove shadow - all background to be close to white or white. I know that sample resolution is very low which complicates this task. Thanks for help Quote
Alfred Posted November 27, 2021 Posted November 27, 2021 The images are not only low resolution but also very blurred, and the time taken to remove the shadow, increase the contrast and sharpen everything up would be better spent retyping the text. Even on the second page there isn’t a large amount of text, but I don’t know how easy it would be to find suitable replacements for the Wawel Dragon and other pictures.

RichardMH Posted November 27, 2021 Posted November 27, 2021 The shadows are bluish so you can use that to create a mask. Then curves to lighten and maybe change to B&W after. A bit fiddly. Quote
impact Posted November 28, 2021 Author Posted November 28, 2021 I finally managed to do it myself, here is what I did: Filters > Frequency Separation... and I choose value which make shadow invisible and text possibly sharp and clear Delete Low Frequency layer Layer > New Adjustment Layer > Levels and move both White and Black closer to "peak" to make background much more white and text more black Document > Flatten Flood Select Tool with value 4% and I clicked on "gray background" then Delete Erase Brush Tool to remove rest of artifacts and dust Finally again a little Levels or Brightness/Contrast to make text slightly darker Here is what it looks like. Maybe someone has another idea how to reach this goal? markw, RichardMH and firstdefence 3 Quote

Thanks for good advise hahaha sure I know Microsoft Lens and Adobe Scan which are very good I also own normal flat scanner but this files are not mine. Question was what to do with that bad source image. Quote

Sure it was not mine, normally I use good flashlight which is better than flash and special apps like I mentioned in last post. I had only problem what to do with that garbage which is already done anyway Affinity Photo again proved that it's gread tool. Quote
