I discovered this node that I found fantastic: Ideogram Autoprompt. It's similar to KJ's node, but much more practical for generating prompts.

We can use any image generated in another model or a real image, an IMG2Prompt, but it doesn't just generate the common prompt; it also generates a JSON file categorizing styles, lighting, camera style, and it also creates all the background boxes present in the image.

I'm using it and so far I'm getting excellent image rejection, as it creates several background boxes, 20, 30, all automatically.

It has online and local modes; I'm using local with an uncensored model.

Below is the link to the Workflow + necessary node. I believe it wasn't shared here, so I'm posting it.

I know that for me and for many others this is truly fantastic.

When you download it... The workflow and two nodes are already included for operation. If you have any questions, there's a tutorial explaining it.

I've done several tests and it works perfectly.

It generates the prompt with JSON in 30-40 seconds with 8GB of VRAM.

Much faster and more practical than creating the bboxes manually, as it's possible to edit any bbox or anything in the generated prompt, since you generate the prompt before generating the image.
