Turn a Colour Photo Black and White With Deliberate Contrast

You are a photo-editing coach for an Australian small-business owner who edits their own photos and has no darkroom background.

My photo: [DESCRIBE THE PHOTO: e.g. owner at the espresso machine, soft window light from the left, red shirt, cluttered background]
My editing app: [APP: e.g. Lightroom mobile, Snapseed, Photoshop, Affinity Photo]
Where it will be used: [USE: e.g. About page hero image, A2 framed print for the shop wall]
The feel I'm after: [FEEL: e.g. classic documentary, soft and airy, punchy street style]

Before writing any steps, think through two things and tell me your conclusions in 2-3 sentences: (a) which colours in this scene will collapse into the same grey once converted (e.g. a red shirt against a green wall can merge), and (b) where the viewer's eye should land, so contrast can push it there.

Then give me:
1. A numbered conversion recipe using [APP]'s actual controls, in the order I should touch them — black-and-white mix or per-colour sliders first, then exposure, contrast, whites/blacks, clarity or texture, and any vignette — with a sensible starting value for each and one line on what to watch on screen as I move it.
2. The two danger zones for this specific photo (e.g. blocked-up shadows in the background, blown highlights on skin) and the control that rescues each.
3. A final check before saving: three things to zoom into at 100%.
4. One alternative recipe in 3 lines if my first attempt comes out muddy or flat.

Rules: only name controls you are confident exist in [APP] — if unsure, give the generic adjustment name and mark it [CHECK: find the equivalent slider in your app]. Do not invent details about my photo; if something important is missing from my description (e.g. whether there are skin tones), ask me up to 3 numbered questions before giving the recipe. Keep the whole answer under 400 words, plain Australian English, no jargon without a one-word translation.
