# Fictional reference-image practice sample Created and reviewed 7 October 2026 using the built-in imagegen tool. No model version or generation settings were exposed, so none are claimed. These are original AI-generated fictional product images, not photographs of a manufactured product. They contain no personal identity or brand. Input: mug-subject-reference.webp. Output: mug-reference-edited.webp. Reference-generation request: one unbranded cream ceramic mug with a broad sage-green rounded handle on its right and a narrow sage-green horizontal rim. Three-quarter view, neutral grey studio background, soft diffused light. No text, logos, people or watermark. Observed edit request: use the attached first image as the subject reference. Preserve the cream mug, green right-side handle and green rim. Change only the setting and lighting to a warm pale oak tabletop beside a softly lit window, with a plain warm beige wall. Keep the three-quarter view, original proportions and one mug. No extra objects, people, text, labels or watermark. Subject fidelity matters more than decoration. Visual check: the broad right-side handle, cream body and green rim remain recognizable; the grey studio backdrop becomes a window-lit tabletop. Lighting and small surface details differ. This is not pixel-identical preservation. No face-preservation claim is supported by this object example. Practice: download the input, attach it in a compatible image editor, paste the observed edit request, and compare the handle, rim, proportions and extra objects before judging beauty. Change one instruction at a time. Compatibility with listed platforms is based on documentation; only the built-in imagegen workflow was run for this example. Generated output varies.
