I use Adobe Scan to scan stuff: receipts, handwritten notes, mail to save, etc. Source: almost 3 years ago

Use a PDF scanner app on your phone. However, do NOT use iOS Notes' scanning function. I recommend Adobe Scan, as it eases the process of converting the PDF into an image file. Source: about 3 years ago

Both the Adobe Scan and Microsoft Lens scanner apps work really well: https://acrobat.adobe.com/us/en/mobile/scanner-app.html. Source: about 3 years ago

If the picture is of law quality or scratched try to improve it before colorizing. You can do it using Photoshop or GIMP (HSV contrast, white balance, noise reduction, etc.) or use an online tool. I can recommend You the three following: https://imagecolorizer.com/repair.html, https://www12.lunapic.com/editor/, https://hotpot.ai/restore-picture?s=side-ad. Hard to say which one is better, depends always on picture... Source: almost 3 years ago

It's a great idea, I absolutely second this. The only problem is that grandma's photo may be too old and faded, in this case you'll have to use something like Photoglory or ImageColorizer to restore it and probably add some color. Source: almost 3 years ago
