H3 Image Tips: 16MP via ComfyUI Workflow Plus Detailed Prompts Yields Best Results
gatortux · reddit · 2026-11-11
Reddit user gatortux shares hands-on tips for H3 Image: early generations were underwhelming, but switching to the official ComfyUI workflow at 16MP produced the best results; prompt upsamplers or very detailed prompts written with Claude/ChatGPT further improve output.
The post includes a full example prompt for an American comic-book cover (STARBREAKER #1), precisely describing masthead typography, hero pose, lighting and palette, plus layout elements like barcode and publisher logo. The resulting image has fully legible lettering and clean composition, demonstrating the value of long structured prompts for complex layouts.
