My journal for tracking random updates and experiments from BVIS Tech!
Nano Banana is the latest version of (Google) Gemini's 2.5 Flash, an AI image generator and editor. Nano Banana has been getting a lot of praise lately, and one important reason is that it's getting quite good at editing existing images without changing important details.Â
I tested an earlier version of this tool in the spring, and I decided to check it out again after the most recent update. I'm primarily interested in using this tool to help with tactile graphic production.
I started by giving a basic description of tactile graphics for the model. "When creating tactile images, we first remove all of the background information. We then trace the main figure in the image. The final product looks a bit like a coloring book page, with just a black drawing of the original image. We use thicker lines for the outline."
Simple images work great with this. Complex images will need more attention, but the black and white versions created by the model will be easier to work than the original color images.
