Step 2: Write a Powerful Promptwith ChatGPT
Be specific! Describe the scene, mood, camera angle, and action.
Use dynamic movement and emotion for maximum engagement.
Example prompt: “Create a hyper-realistic, highly detailed image of a mischievous adult monkey with expressive, human-like eyes and a playful smile. The monkey is sitting on a motorbike parked on a bustling Indian street, wearing a rugged biker jacket and a red gamcha (traditional scarf) wrapped around his neck. He’s holding a mounted GoPro camera, capturing his vlog. The image should appear as if taken from the GoPro’s point of view, with a subtle fisheye perspective. Include background elements like street signs, chai stalls, Indian auto-rickshaws, and a slightly blurred crowd to set the location. Use natural lighting with cinematic depth, shallow depth of field, and warm color tones. 4K resolution, optimized for use in thumbnails, reels, and ad creatives.“
