A useful Stable Diffusion negative prompt often includes low quality, blurry, bad anatomy, bad hands, extra fingers, missing fingers, distorted face, poorly drawn eyes, deformed body, duplicate limbs, watermark, logo, text, signature, jpeg artifacts, and noisy background. For better results, customize the list by image type instead of pasting every term into every generation.

Midjourney commonly uses the --no parameter to exclude unwanted elements. For example, you can add --no text, watermark, logo, extra fingers, blurry face, messy background to the end of your prompt. Keep the list focused, because too many unrelated exclusions can make the model ignore the main image direction.

Support depends on the tool and model interface. Some AI image generators provide a dedicated negative prompt field, while others respond better to positive framing, such as “clean background with no visible text” or “natural hands with five fingers.” For Flux, ChatGPT image generation, and similar tools, check the current interface and rewrite exclusions as clear visual requirements when needed.

Try terms such as bad hands, extra fingers, missing fingers, fused fingers, malformed hands, poorly drawn hands, duplicate hands, deformed wrists, broken fingers, unnatural hand pose, and bad anatomy. Also improve the positive prompt by describing natural hands, relaxed fingers, visible hand position, and realistic body proportions.

Use terms such as text, watermark, logo, signature, username, caption, subtitle, letters, words, brand mark, QR code, label, typography errors, and unreadable text. For posters or product images, pair them with positive instructions like clean blank background, no visible branding, and simple composition.

Not always. Long negative prompts can help in Stable Diffusion workflows, but they can also dilute the main prompt or introduce conflicting signals. The best negative prompts are specific to the image problem. For a portrait, focus on face, hands, skin, eyes, and lighting. For product photography, focus on shape, labels, reflections, background, and perspective.

Yes. For portraits, negative prompts can reduce bad hands, unnatural skin, distorted faces, blurry eyes, and harsh shadows. For product images, they can help avoid warped packaging, fake text, random logos, wrong perspective, busy backgrounds, and strange reflections. Results still depend on the image generator, prompt quality, input image, and generation settings.
