AI Quick Tips 267: Nano Banana image prompting best practices

Here are 6 best practices from Google to consider when prompting their image generation models (Nano Banana and Nano Banana Pro)

Be Hyper-Specific: The more detail you provide, the more control you have.
1. Instead of "fantasy armor," describe it: "ornate elven plate armor, etched with silver leaf patterns, with a high collar and pauldrons shaped like falcon wings."
Provide Context and Intent: Explain the purpose of the image. The model's understanding of context will influence the final output.
1. For example, "Create a logo for a high-end, minimalist skincare brand" will yield better results than just "Create a logo."
Iterate and Refine: Don't expect a perfect image on the first try. Use the conversational nature of the model to make small changes.
1. Follow up with prompts like, "That's great, but can you make the lighting a bit warmer?" or "Keep everything the same, but change the character's expression to be more serious."
Use Step-by-Step Instructions: For complex scenes with many elements, break your prompt into steps.
1. "First, create a background of a serene, misty forest at dawn. Then, in the foreground, add a moss-covered ancient stone altar. Finally, place a single, glowing sword on top of the altar."
Use "Semantic Negative Prompts": Instead of saying "no cars," describe the desired scene positively: "an empty, deserted street with no signs of traffic."
Control the Camera: Use photographic and cinematic language to control the composition.
1. Terms like wide-angle shot, macro shot, low-angle perspective.
