1. Anatomy & Body Negative Prompts

HANDS FINGERS ANATOMY

Hand & Finger Negative Prompt

deformed hands, mutated hands, extra fingers, missing fingers, fused fingers, extra thumb, six fingers, three fingers, claw hand, alien hand, malformed hand, distorted hand, bad hand anatomy, missing hand, extra hand, merged fingers, webbed fingers, fingerless, stub, amputated, detached fingers, floating fingers
Why this works: SDXL's #1 failure point is hands. This comprehensive list targets every possible hand deformity—extra digits, missing fingers, fusion, wrong counts.
BODY PROPORTIONS LIMBS

Body Proportions Negative Prompt

bad proportions, deformed body, distorted limbs, extra limbs, missing limbs, mutated anatomy, wrong body ratio, elongated torso, short legs, long arms, tiny head, giant head, no neck, twisted spine, broken back, impossible pose, floating body, disconnected limbs, disproportionate
Why this works: Targets common proportion errors—elongated torsos, short legs, tiny heads, twisted spines—that SDXL frequently produces without guidance.
FACE EYES SKIN

Face & Skin Negative Prompt

deformed face, bad eyes, unrealistic skin, plastic skin, airbrushed, smooth skin, mannequin, wax figure, statue, doll, mask, no texture, glassy eyes, dead eyes, mismatched eyes, cross-eyed, asymmetrical face, blurry face, low resolution face, cartoon face
Why this works: "Plastic skin" and "airbrushed" block the over-smoothed AI look. "Glassy eyes, dead eyes" ensure eyes look alive and natural.

2. Quality & Artifact Negative Prompts

QUALITY RESOLUTION DETAIL

Low Quality Negative Prompt

blurry, low resolution, pixelated, noisy, grainy, out of focus, soft focus, low detail, undersampled, jpeg artifacts, compressed, low quality, bad quality, poor quality, amateur, ugly, bad art, beginner, mediocre, lowres, worst quality
Why this works: Explicitly blocks low-quality results. SDXL understands these quality descriptors and will avoid generating images matching these terms.
ARTIFACTS DISTORTION GLITCH

AI Artifact Negative Prompt

artifact, glitch, distortion, warped, twisted, broken, corrupted, ghosting, double image, overlapping, clipping, truncation, seam, crease, unnatural, weird, bizarre, nonsensical, abstract, chaotic, messy, cluttered
Why this works: Targets AI-specific artifacts—ghosting, warping, double images—that occur when SDXL tries to generate beyond its capabilities.
WATERMARK TEXT LOGO

Watermark & Text Negative Prompt

watermark, signature, text, writing, letters, words, logo, brand, copyright, credit, artist name, stock photo watermark, getty, shutterstock, adobe stock, alamy, depositphotos, watermark text, caption, label
Why this works: SDXL sometimes hallucinates watermarks from training data. This negative prompt suppresses Getty, Shutterstock, and other stock watermark artifacts.

3. Style & Aesthetic Negative Prompts

NON-PHOTO ART STYLES CGI

Non-Photorealistic Negative Prompt

cartoon, anime, illustration, painting, drawing, digital art, 3D render, CGI, computer generated, vector art, clip art, coloring book, sketch, line art, manga, comic, cel shaded, watercolor, oil painting, acrylic, pastel, charcoal
Why this works: Essential for photorealistic goals. This blocks every non-photographic style, forcing SDXL toward true-to-life photography rather than artistic interpretation.
OVER-PROCESSED FILTER HDR

Over-Processed / HDR Negative Prompt

over-processed, oversaturated, too sharp, HDR, tonemapped, instagram filter, beauty filter, photoshopped, airbrushed, retouched, edited, manipulated, fake, artificial, unnatural colors, neon, glowing, radioactive, unrealistic lighting
Why this works: Blocks the over-cooked HDR look and heavy editing that makes images look fake. Essential for natural, authentic photography results.
CONTENT SAFETY NSFW

Content Safety Negative Prompt

nudity, nude, naked, exposed, gore, blood, violence, explicit, sexual, porn, NSFW, disturbing, unsettling, scary, horror, creepy, grotesque, disgusting, offensive, hateful, harmful, inappropriate, underage, child
Why this works: For family-friendly, professional applications, this negative prompt blocks unwanted content types and ensures safe-for-work generations.

🎯 MASTER NEGATIVE PROMPT (Copy-Paste Ready)

Combine everything into one comprehensive negative prompt for maximum quality:

deformed, mutated, bad anatomy, disfigured, ugly, wrong proportions, extra limbs, missing limbs, fused fingers, extra fingers, missing fingers, claw hand, bad hands, six fingers, three fingers, amputee, deformed face, bad eyes, glassy eyes, dead eyes, plastic skin, smooth skin, airbrushed, wax figure, doll, mannequin, blurry, low resolution, pixelated, noisy, watermark, signature, text, logo, cartoon, anime, illustration, painting, drawing, digital art, 3D render, CGI, oversaturated, over-processed, HDR, fake, artificial, nude, gore, violence

Why this works: This master negative prompt combines anatomy fixes, quality boosters, style blockers, and safety filters into one comprehensive list. Paste this at the end of EVERY SDXL generation for consistently better results.

Mastering Negative Prompts in SDXL

🎯 What Are Negative Prompts?

Negative prompts tell SDXL what you DON'T want to see. They're as important as positive prompts. Without negative guidance, SDXL defaults to common training artifacts like bad hands, plastic skin, and wrong proportions.

🖐️ Hands Need the Most Negatives

Hands require the most extensive negative prompts: "deformed hands, extra fingers, missing fingers, fused fingers, claw hand, bad anatomy." SDXL's training data has poorly labeled hands—negatives correct this.

📊 Negative Prompt Strength

Most interfaces have "Negative CFG Scale" or "Guidance Scale for Negatives." Higher values (1.5-2.5) enforce negatives more strongly. Start at 1.5, increase if artifacts persist.

🎨 Style Negatives for Realism

For photorealistic goals, block non-photo styles: "cartoon, anime, illustration, painting, 3D render, CGI." Without these, SDXL may drift toward artistic interpretation rather than photography.

🔧 When to Add More Negatives

See a specific artifact? Add it to negatives. Extra finger? Add "extra fingers." Weird lighting? Add "unnatural lighting." Build your negative prompt iteratively based on observed failures.

⚖️ Positive vs. Negative Balance

Too many negatives can over-constrain SDXL. Start with master list above, then remove negatives that aren't relevant to your specific prompt. Balance is key—only block what's actually problematic.
