Grayscale Image — frequently asked questions

What's the difference between Grayscale and Black & white?
Grayscale keeps smooth shades of grey. Black & white makes every pixel pure black or white at the level you choose, for a stark, high-contrast look.
Can I get a softer effect?
Yes — for Grayscale and Sepia, lower the Strength to blend part of the original colour back in.
What is Negative?
It inverts every colour, like a photographic negative.
Can I convert a whole folder?
Yes — add many images and they all get the same look.
