How to compare black-and-white looks on Mac
Compare ten monochrome photo treatments, refine a Noir look, and inspect the result beside the color original on your Mac.
- What you'll achieve
- You'll have a refined Noir preview with adjusted shadows and highlights, plus a draggable before-and-after comparison against your original color photo.
- What you need
- Black & White Editor - Effects 3.0 for Mac.
- A color photo on your Mac to compare in black and white.

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.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.

Select Noir among the monochrome looks. The app opens the adjustment view with Noir applied so you can refine its tones.

Set Shadows to 10% to bring out darker details while retaining Noir's contrast. Inspect the large photo preview after the adjustment.

Set Highlights to −24% to hold detail in bright areas. Leave Shadows at 10% so the tonal balance remains consistent.

Use the Darkroom stage control to switch to Explore. The panel shows ten black-and-white looks, with Noir still selected.

Turn on Compare with original. The canvas displays the color original on the left and the black-and-white result on the right, separated by a movable divider.

Drag the Explore before/after divider toward the left to reveal more of the Noir result. Compare the two sides and select another interpretation from the thumbnail panel if you want to test a different mood.

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.
