The prompt

Change one marked area of my image and leave the rest untouched. Image: [describe it: e.g. a shop counter with a blank wall behind it] Region to edit: [where it is, e.g. the top-right quarter, or the box I drew from about 60% to 95% across and 5% to 40% down] What should be inside that region: [e.g. a framed chalkboard menu with three hand-drawn coffee cups and no readable words] Everything outside the region: identical to the original: same objects, colours, shadows and perspective. Prompt structure: 1. One sentence describing the whole finished image. 2. One sentence describing exactly what fills the marked region, with its size and position relative to nearby objects (e.g. "above the left end of the counter, about as wide as the cash register"). 3. Matching light: shadows fall [direction], colour temperature [warm / neutral]. Avoid: spill outside the box, a new perspective, extra objects, text or logos, and changes to any person's face. If you're using ComfyUI, plan the region with the Create Bounding Boxes node and copy the coordinates into sentence 2.
