How to Combine Two Images in Nano Banana 2 Pro for Product Shots
Most people use Nano Banana 2 Pro one image at a time. The feature they miss is blending: feed it two photos and it merges them with matching light and perspective. For product photography that replaces an entire afternoon of masking.
Here is the workflow, the prompt structure that makes it behave, and the cases where it still embarrasses you.
Why is blending better than cut-and-paste editing?
When you cut a product out and paste it on a new background in a normal editor, the light rarely matches. Shadows point the wrong way, color temperature is off, and the edges look cut. The model, by contrast, reads both images and generates a merged result where shadows and tone are inferred together. You trade pixel control for physical plausibility — usually a good trade for marketing shots.
The two-image blend workflow
- Pick a clean product photo on a simple or removable background.
- Pick a scene photo with clear, directional lighting.
- Upload both and label their roles in the prompt: “Image 1 is the product. Image 2 is the scene.”
- Describe placement and scale: “Place the bottle on the left third of the wooden table, roughly 15cm tall.”
- Describe light and shadow: “Match the window light from the right; cast a soft shadow to the left.”
- Generate, then regenerate the seed if edges look fused.
Labelling the images in words matters far more than people expect. Without it the model guesses which one is the subject, and it guesses wrong a fair share of the time.
How much control do you get over placement?
More than the base model but not what a designer would call precise. Directions like “left third” and “in front of” work. Exact coordinates do not. For catalog work where every shot needs the product in the identical spot, blend one hero and then composite the rest manually — the model will not hold a fixed position across generations.
Where do blends visibly break?
Glass, chrome, and transparent objects are the hardest, because the model cannot model refraction properly and reflections end up generic. Reflections in a polished surface often show the wrong thing. And if the scene photo has heavy depth-of-field blur, the product may be inserted at a mismatched focus plane, looking pasted despite the good lighting.
Shoot the product against something with soft, diffuse light and your success rate jumps.
Who should use this?
Small e-commerce sellers without a studio, agencies producing dozens of lifestyle variants from one product shot, and anyone A/B testing a product in different settings. If you sell glass or jewelry at scale, the failure rate is high enough that you will still want a photographer for hero shots.
Key Takeaways
- Blending two images in Nano Banana 2 Pro replaces manual masking for product shots.
- Label each image’s role in the prompt and describe placement, scale, light, and shadow.
- Placement follows directions like “left third” but not exact coordinates.
- Glass, chrome, and reflections are the weakest cases.
- Great for lifestyle variants; hire a photographer for hero shots of tricky materials.
