Blur the background of my photo the way a fast lens would. Progressive blur that increases with distance, not a single flat blur over everything. Keep the subject completely sharp with a clean, natural edge — including hair, where the transition should be gradual rather than cut. Render out-of-focus highlights as soft round bokeh. Leave the subject's colour, exposure and detail untouched.
“Use it” opens the editor with this prompt already loaded — add your photo and generate. Copy works anywhere else: ChatGPT, Gemini, Midjourney.
Real depth of field increases with distance. A flat blur is the giveaway.
