A black-and-white effect can change the mood of a photograph. Black & White Editor - Effects lets you preview ten treatments, refine their tones, and compare the result with the original. This guide follows a real seven-step capture using a landscape photo and the Noir interpretation.

  1. 1.Open a photo and view the monochrome looks

    Open a color picture with Photo. In Explore, review the thumbnails of available black-and-white interpretations. The first preview shows how a neutral treatment changes the picture.

Tips

  • Start by comparing the thumbnails in Explore instead of committing to a look from its name.

  • Move the before-and-after divider across important highlights and shadows to check what each adjustment changes.

  • Watch outThis workflow previews a look and its adjustments; it does not export a finished image.
