Grayscale or black and white?

Grayscale keeps all the shades of grey, like a classic black and white photo. Black and white only uses two tones, like a photocopy, which suits signatures, drawings and documents.

Tips

  • Start with a well lit picture for the best contrast.
  • Keep the colour original in a separate folder.
  • For forms and scanned notes, strict black and white makes the file cleaner.
