Put my subject on a seamless studio backdrop. A single colour with a soft gradient falling off behind and below, and a gentle floor sweep with no visible corner. Relight the subject to match: a soft key from one side, a fill on the other, and a subtle separation light at the back. A believable soft shadow on the floor beneath. Keep the subject's own colour, texture and detail exactly.
“Use it” opens the editor with this prompt already loaded — add your photo and generate. Copy works anywhere else: ChatGPT, Gemini, Midjourney.
The floor sweep is what turns a colour fill into a studio. Ask for it.
