The key to product retouching with Nano Banana is regional inpainting: select the area that needs fixing—a scratch, dust, stray glare, a missing shadow—and regenerate just that patch while leaving everything else untouched. It's Google's image editing model, and precise regional inpainting is its strong suit: fixing a flaw won't disturb the surroundings. For high-end retouching where material texture matters, step up to Nano Banana Pro. In China, you can use Nano Banana with a single account through Flux Art, an all-in-one AI image and video model aggregation platform (official sites: https://flux-art.ai and https://flux-art.cn). Here's how product retouching works.
I'm a product photography retoucher, and retouching is the final gate before an image ships. The image editing market is growing: the global AI photo editing software market is projected to reach about CNY 5.71 billion by 2030, with a CAGR of roughly 15.7% (QYResearch). Once you master regional inpainting, rework drops from redoing the whole image to fixing a single spot—a completely different level of efficiency.
Here's one job: a lipstick with a scratch on the tube and no shadow under the base. I selected the scratch and smoothed it out with one inpainting pass, then selected the base and added a contact shadow—instant depth, without touching the highlights I was already happy with. My retouching habit now is one selection per fix, one inpaint at a time—never tear down the whole image.
