Nano Banana 2 vs GPT Image 2：同一提示词实测对比

Cut out the product from the reference image and make an e-commerce main image: pure white background (#FFFFFF), product centered at about 80% of the frame, front view slightly from above, with a soft natural shadow underneath. Fix perspective and white balance, remove clutter and glare, keep the shape, color and print unchanged, sharp and high resolution.

Turn the product in the reference image into a Christmas product photo: the same mug, keeping its exact shape, color and leaf print, filled with hot cocoa and mini marshmallows, standing on a snowy white surface with pine sprigs, red berries, a cinnamon stick and a small wrapped gift box. Warm fairy-light bokeh in the background, soft window light, a clean holiday e-commerce look with empty space above the product for text.

Make a UGC-style social photo with the product in the reference image: a casual phone shot of a hand in a cozy oversized knit sleeve holding the same mug, keeping its exact shape, color and leaf print, above a lived-in cozy bed with a book, a plain laptop with no logo and a knitted blanket. Soft morning window light, slightly imperfect framing, natural colors, like a real customer's Instagram story, no text or logos.
