About Black and white photo
Turn a colour photo into greyscale, either natural or with high contrast. Greyscale is typically computed with weights of about 30 percent red, 59 percent green and 11 percent blue, matching how the eye perceives brightness, so skies and skin tones keep believable tones.

Frequently asked questions
When does black and white work best?
Photos with strong shapes, contrast and texture, like portraits and street scenes. It also rescues pictures with distracting or clashing colours.
Which style should I choose?
Natural keeps soft tones and suits portraits. High contrast makes darks deeper and lights brighter, which gives a dramatic look for buildings and street scenes.
Can I go back to colour?
Not from the saved black and white file, because the colour data is gone. Keep your original photo and make the greyscale as a separate copy.
