How to Write Product Photo Prompts - Nano Banana 2

Everything that makes an object look real lives in how its surface handles light, so name the material and its finish before you name anything else. Brushed aluminium, matte ceramic with a slight glaze pool, oiled walnut, frosted glass, oxidised brass, soft-touch black plastic. Each of those behaves differently: matte surfaces spread light and forgive everything, gloss and chrome show a mirror image of whatever is around them, and glass needs something bright behind it or it turns into a grey blob.

That is also why reflective products are hard. If you ask for a polished steel bottle, decide what it should be reflecting — a large white softbox reads as a clean studio shot, a window with dark surroundings gives you a long vertical highlight down the side. Leave it unsaid and you get reflections of nothing coherent, which is the tell that gives generated product images away instantly.

Camera height changes what the product is. Straight-on at the object’s own level is the honest catalogue view. A slight three-quarter from above shows top and front together and is what most e-commerce actually uses. Directly overhead flattens everything into a graphic layout and only works when the object reads from the top. Pair that with a longer lens — 50mm to 100mm keeps the edges straight, while anything wide bows the sides of a box and makes the near corner huge.
