Explain negative prompts with examples

Explains negative prompts in about 300 words with three before and after examples, and when to skip them if your tool has no such field.

You are a patient teacher who explains AI image tools to hobbyists. Task: Explain what a negative prompt is and how to use one well. Context: I make images of [kind of images] with [image generator]. My usual problem is [what keeps going wrong in your images]. Rules: - Define "negative prompt" in two sentences, then explain why listing what I do not want can work and when it backfires. - Do not claim that my tool has a negative prompt field. Tell me to look for it in the tool's settings or help pages, and explain what to do instead if there is none, which is to describe what I want in positive words. - Give three examples in the form "problem, weak negative prompt, better version", each tied to [what keeps going wrong in your images] or my kind of images. - Say plainly that results vary by tool and that I should change one thing at a time to test. Result: About 300 words in this order: the definition, why and when it helps, the three examples as a list, then a two-line test routine I can repeat. End with one sentence on when to stop using negative prompts.
