Black and white in Lightroom

Lightroom is one of the strongest places to craft intentional black and white photos because the B&W Mix (or Black & White Mix) panel lets you decide how each original color becomes gray.

Desktop / Classic workflow

1. Open the photo in Develop.
2. In the Profile browser, pick a B&W profile instead of only dropping saturation.
3. Use the Black & White Mix sliders (red, orange, yellow, green, aqua, blue, purple, magenta) to separate tones - darken blues for sky punch, lift oranges for skin.
4. Set overall range with Exposure, Contrast, Highlights, Shadows, Whites, and Blacks.
5. Add local masks only after the global conversion reads clearly.

Avoid “Saturation −100” as your final method. That is closer to flat desaturation than to channel-aware mono. For the math behind luminosity weighting, read how grayscale conversion works and luminosity vs desaturation.

Lightroom Mobile

The same ideas apply: switch Treatment / Profile to Black & White, then open the B&W Mix controls. Mobile is capable enough for travel edits; reserve Classic when you need denser masking.

When a browser preview is enough

Opening Lightroom for every cull is slow. Run keepers through the grayscale photo filter or main black and white filter first. If the structure fails in Rec. 709 gray, it rarely becomes a hero in Lightroom either.

For many files with one shared baseline, use the batch black and white converter.
