Brief Flux.2 for an editorial lifestyle photograph, no negative prompts
A camera-aware natural-language brief for Flux.2, which — like other flow-matching and DALL·E-style models — has no negative-prompt field; unwanted elements are steered out through what you describe, not through an exclusion list.
The prompt
Ready to copy — highlighted parts are example details you can swap.
a small independent bookshop café corner, warm and lived-in, a young woman in a cream knit sweater reading a paperback at a window table, soft candid expression, late-afternoon window light, warm and slightly hazy, long soft shadows, shot as if on a Fujifilm X-T5 with a 35mm f/1.4 lens, warm Kodak Portra 400 color grade, gentle film grain, slightly lifted blacks, composition: rule-of-thirds, window and bookshelves framing the left third, generous negative space on the right

Why this works
Flux.2 has no --no parameter and no negative-prompt input of any kind — unlike Midjourney or Stable Diffusion, its architecture is steered entirely through positive description. If you want to exclude something (other people in frame, visible text, a cluttered background), that has to be written as a positive statement inside the brief itself, e.g. "an otherwise-empty café with no other patrons visible," rather than assumed as an exclusion the model will honor from a separate field — treating it like SD's negative box will just be silently ignored. Flux.2 responds strongly to specific camera/lens/film-stock language for photorealism and to plain-prose compositional instructions (rule-of-thirds, where the negative space sits), so put the same care into composition_note that you'd put into a subject description.
What you get back
A warm, editorial-style lifestyle photograph matching the described scene and framing — the film-stock reference (Portra 400, in this example) will read as an approximate color-and-grain feel rather than a technically exact emulation of that real film.
