Nano Banana 2.1 Scene Concept Art: Worldbuilding Atmosphere Exploration

Building on the text-to-image capabilities of the Gemini image model family (nano-banana / Gemini 2.5 Flash Image and the like), this is an exercise in "worldbuilding visual exploration": first generate a baseline concept image from a text description, then iteratively edit it with natural language at multiple points (lighting, weather, materials, period feel) along the same camera angle, observing how consistent the subject and composition remain across multiple rounds of editing. This entry passes a reference base image via image_input as the scene anchor, and controls the output with prompt, resolution, aspect_ratio, and output_format, demonstrating the model's typical use in concept design, storyboard previsualization, and mood boards. It suits early-stage game/film concept work, scene atmosphere comparisons, and multi-version visual iteration that must preserve the same spatial logic. Note: The official attribution and version naming of nano-banana are not consistent across third-party sources; this piece only demonstrates the parameters declared in the schema and does not touch on unverified capabilities such as resolution limits or openness.
