What you will get

Your photo as a high-contrast black-and-white image, with rich blacks, bright whites, strong tonal separation, fine grain and crisp detail where you pointed, uncropped and with the same composition.

Why it works

High contrast black and white depends on strong shapes, so the prompt asks for rich blacks, bright whites and clear tonal separation. Naming where to keep crisp detail, face, building or texture, points the edit. Leaving the crop alone keeps your composition.

Common mistake

Highlights or shadows turn into flat patches with no detail.

Fix: Ask for “deep blacks but keep texture in the shadows, bright whites but keep detail in the highlights”. Some clipping is fine, a lot is not.

Also watch for

The result looks flat, as the tip warns for dull photos. Start from a photo with strong light, clear shapes and shadows. Flat overcast light will not gain depth from a conversion.
The picture is cropped or a person is changed. Keep “do not crop or change the composition” and add “keep faces exactly the same”.

Try a variation: film noir mood

Add “hard side lighting, deep shadows across half the frame and a slight vignette”. This suits street photos and portraits with a strong light source.
