Google's enhanced AI image maker Nano Banana Pro has some impressive abilities thanks to Gemini 3 powering it. Gemini 3 gives it an almost architectural sense of how light, space, texture, and subject identity work together inside a photograph. Instead of manipulating pixels in a literal way, Nano Banana Pro interprets an image the way a designer or art director might.

You describe an edit the way you might describe a dish to a waiter, and it returns something that feels like a chef actually understood you. That makes it easy to experiment, but it also means you can get better results when you know how to steer the system. Here are some of the best ways to make photo edits with Nano Banana Pro.

1. Alter the lighting

Most editors let you brighten, darken, or tweak the temperature. Nano Banana Pro lets you tell the model to pretend the lighting setup was entirely different from the start. Because it rebuilds the scene’s illumination rather than simply nudging pixels around, you can turn a flat snapshot into a shot that looks intentionally staged.

Nano Banana Pro recalculates the position, intensity, and texture of light as if a different environmental condition existed during the capture. This produces transformations that feel plausible and fully integrated rather than filtered or tinted. I started with the photo below to showcase some of what it can do.

I then asked Nano Banana Pro to make the lighting a late-afternoon golden hour with warm directional sunlight from the right, but keep facial features unchanged.”

The AI reworked where the sun sits in the sky. It introduced side lighting along the shoulders and lapels, warms the color palette to amber-gold, and develops longer shadows across the gravel and foliage. The water in the background shifts to reflect that warmth. The sky takes on a low-sun hue, and the subject gains a more dimensional silhouette because the model calculates new highlight maps. You can see the result below.

This kind of lighting adjustment can be pushed in other directions as well. You could instruct the model to generate a soft, diffused, overcast mid-morning look or to push it toward a moody, cinematic twilight with deeper blues and more contrast around the face. Because Nano Banana Pro maps the photo’s surfaces three-dimensionally, it can alter reflections, gradients, and transitions across clothing and skin.

2. Background shifting

Background replacement is one of the most common requests in photo editing, but it often fails because the subject looks discarded onto a new scene like a sticker. Edges become too sharp, lighting doesn’t match, and shadows disappear or contradict the environment. Nano Banana Pro avoids these issues by understanding the spatial logic of the image.

For this photo, the model studies the subject’s shape, stance, shadows, reflective surfaces, and color temperature. It ensures the new background interacts correctly with all of these elements when asked to “Replace waterfront with an elevated city terrace at dusk, match shadows and suit reflections to the cooler urban lighting.”

This instruction doesn’t ask the AI to simply paste in new scenery. Instead, it instructs the model to rethink where the ambient light is coming from, how bright it should be, how that should affect the suit fabric, and how shadows should fall. Nano Banana Pro then reconstructs the new environment in perspective, positions the skyline behind the subject, and adjusts lighting accordingly.

The trick is to treat backgrounds as contextual storytelling tools. If the subject looks like it’s floating, you can correct with a follow-up instruction: “adjust shadow to match light angle in new environment” or “blend foot placement into ground texture naturally.”

3. aiAdding the right banana...er...AI ingredient

Nano Banana Pro isn’t limited to adjusting mood or swapping environments; it can also reorganize the existing contents of a photo with surprising precision. For instance, asking the AI to "Remove the plants and move the boats to the other side of the figure," gives you the image above.

This kind of structural editing relies on the model’s understanding of depth, scale, and spatial continuity. When you tell it to remove something organic, like the plants in the foreground, it evaluates texture, light direction, and the shoreline beneath. Instead of leaving behind smudged patches or obvious fills, the system reconstructs the gravel and stone barrier with convincing continuity.

Nano Banana Pro works well as a replacement for dozens of tools scattered across layers, sliders, masks, and adjustment panels. The advantage isn’t just speed, but being able to convey intent and letting the AI handle the mechanical steps that traditionally required far more technical experience and significant time to do. And even a simple sentence can transform an ordinary image into something that feels pretty real, even if it involves a Kaiju attack.
