How the Nano Banana Editor Works
This page holds the whole Nano Banana family. It opens on version 2, which generates from a prompt and optional references. To edit an existing picture, choose version 1 in the version bar: two modes appear, Generate and Image to Image. In Image to Image you upload one to ten photos and write what should change, because the prompt is still required. The model keeps what you did not mention and rewrites what you did, then saves the result to My Creations. There are no masks or brushes; the change is described in words. Version 1 also offers eleven aspect ratios, two more than the newer versions.
