27 Gemini Nano Banana Prompts for Halloween
Halloween is that perfect time of year when you can go wild with your photos. I’ve been playing around with Google’s new Gemini Nano Banana image model, and honestly, it’s been a game-changer for creating spooky, atmospheric shots.
The model does a really impressive job at editing photos. You can completely transform your regular pictures into something straight out of a horror movie or a gothic photoshoot.
Head over to gemini.google.com or open gemini app, start a new chat, attach your photo, and paste any of the prompts below.
There’s also another option: go to https://aistudio.google.com/, select “generate media,” then choose Nano Banana. From what I’ve noticed, AI Studio seems to have less censoring, which can be helpful for some of the darker, more intense Halloween themes.
I tested out 27 different prompts, and they all gave me pretty impressive results. Here’s what I tried:
1. Mystical Pumpkin Smoke
A woman in an elegant, floor-length black dress stands on a secluded path at dusk. She holds a carved pumpkin (a jack-o’-lantern) from which vibrant orange or purple smoke billows out, shrouding her slightly. The lighting is soft and golden from the setting sun in the background.
