Generated images appear blurry or pixelated
Details are muddy or unclear
Output quality is lower than expected
Add quality descriptors to your prompt:
high resolution, detailed, professional photography, sharp focus, crisp details, 8K quality Check your resolution settings: Make sure you've selected 2K or 4K output if you need high-quality images.
Improve your source image: Low-quality input produces low-quality output. Start with at least 1080p images.
Be more specific: Instead of "a cat," try "a detailed close-up portrait of a tabby cat, sharp focus, professional photography lighting."
Success Rate: 85% of blurry image issues are resolved by adding quality descriptors.
Strange distortions in the image
Unnatural blending or warping
Odd patterns or textures where they shouldn't be
Simplify your prompt: Complex requests increase artifact likelihood. Break complex edits into multiple steps.
Use reference images: Provide clear reference images for the style or subject you want.
Adjust creativity settings: Lower creativity/randomness if you're getting too many artifacts.
Regenerate with slight prompt variations: Sometimes a small wording change eliminates artifacts.
Pro Tip: If artifacts appear in specific areas, use local editing to regenerate just that section rather than the entire image.
Character looks different across generations
Facial features change between images
Body proportions vary unexpectedly
Use the reference image feature:
Generate your first character image
Save it as a reference
For all subsequent generations, upload reference + "Same character as reference image"
Be extremely specific in initial description:
Asian woman, age 30-35, shoulder-length black hair with subtle waves, round face, warm brown eyes, slight smile, wearing navy blazer, professional corporate style Save your prompt: Use the exact same character description for all generations.
Use consistency mode: Enable character consistency in settings if available.
Success Rate: 95% character consistency when using reference images correctly.
Some prompt elements don't appear in the image
Nano Banana focuses on some aspects but ignores others
Prioritize key elements: Put the most important elements first in your prompt.
Repeat important elements: "red car, bright red vintage car"
Use strong descriptors: "prominently featuring," "clearly showing"
Simplify complex prompts: If requesting 10+ elements, break into multiple generations.
Be explicit about quantities:
Bad: "people in a park" Good: "exactly three people sitting on a park bench" Avoid contradictions: Don't ask for "bright sunny day" and "dramatic storm clouds" in the same prompt.
Results don't match your mental image
Style or mood is off
Technical terms are misinterpreted
Use visual reference points:
Instead of: "retro style" Use: "1980s aesthetic, similar to old Polaroid photos" Add context for technical terms:
Instead of: "bokeh effect" Use: "shallow depth of field with blurred background, professional photography with 85mm lens effect" Specify what you DON'T want:
Create a minimalist logo, clean lines, simple geometric shapes, avoid: gradients, shadows, 3D effects, realistic textures Test with simpler versions first: Start with a basic prompt, confirm it's working as expected, then add complexity.
Generation takes longer than the typical 5-10 seconds
Frequent timeouts
"Processing" status for extended periods
Check server status: Visit Google AI Studio status page for service interruptions.
Lower resolution temporarily
Simplify your prompt
Reduce the number of elements in the scene
Avoid peak usage times: Try generating during off-peak hours (early morning/late evening local time).
Clear browser cache: Sometimes cached data causes slowdowns.
Switch networks: If using VPN, try direct connection or vice versa.
Error message: "Rate limit exceeded"
Temporary block from generating images
"Too many requests" notification
Understand your plan limits:
Free tier: Limited generations per day
Starter: ~200 images/month
Pro: ~700 images/month
Premium: ~2000 images/month
Wait and retry: Rate limits typically reset after 1-24 hours.
Batch your work: Plan your generation sessions instead of constant small requests.
Upgrade your plan: If you consistently hit limits, consider upgrading.
Use multiple accounts (carefully): For legitimate business needs, contact support about enterprise options.
"Invalid image format" error
Upload fails silently
"File too large" message
Check file format: Supported formats are JPG, PNG, WebP. Convert GIF, TIFF, or BMP files first.
Maximum: Usually 10-20MB depending on your plan
Compress images using TinyPNG or similar tools
Resize excessively large images (>5000px is usually unnecessary)
Check image content: Images with extreme content may be rejected. Ensure compliance with content policy.
Remove metadata: Some EXIF data causes upload issues. Strip metadata before uploading.
Try different browser: Upload issues sometimes occur in specific browsers.
Changes apply to unintended parts of the image
Edits "bleed" beyond selected area
Background changes when editing foreground (or vice versa)
Be more precise with selection:
Use smaller, more accurate brush strokes
Define the area explicitly in your edit prompt
Provide contextual anchors:
Instead of: "Change shirt to blue" Use: "Change the woman's shirt to blue, keep everything else including the background, pants, and accessories exactly the same" Use multiple smaller edits: Instead of one big change, make incremental adjustments.
Reference surrounding elements:
"Change only the car color to red, maintain the street, buildings, and sky exactly as they are"
New elements look out of place
Lighting doesn't match
Style inconsistency between original and edited areas
Match style explicitly in your edit prompt:
Change the background to a beach scene, maintaining the same lighting direction, color temperature, and photographic style as the original image Reference original properties:
Add a coffee cup on the table, rendered in the same realistic photographic style with consistent lighting and shadows Use "seamless integration" language:
Seamlessly integrate a [new element] into the scene as if it was photographed at the same time with the same camera Make smaller, more subtle changes: Dramatic changes are harder to integrate naturally.
Text appears garbled or misspelled
Letters are distorted or unclear
Text is illegible
Keep text under 25 characters: Nano Banana handles short text better.
Use simple fonts implicitly:
"Modern sans-serif text reading 'SALE' in bold letters" rather than complex script fonts Large, clear text displaying 'OPEN' in white letters on dark background, highly legible, professional signage style Consider adding text post-generation: For critical text, use design tools after generation.
Use all caps: ALL CAPS TEXT tends to generate more clearly than mixed case.
Success Rate: 60-70% for text under 25 characters, drops significantly for longer text.
Objects you didn't request appear in images
Consistent unwanted background elements
Random people or objects in the scene
Use negative prompts explicitly:
Modern kitchen interior, clean countertops, minimalist design. Exclude: people, food, clutter, decorations, appliances on counters Be specific about empty spaces:
Empty parking lot with exactly zero cars, clean pavement, no vehicles Solo portrait of one person against plain backdrop, no other people, no background distractions Product photography of watch on white seamless background, isolated object, nothing else in frame
Colors too bright or neon
Washed out or desaturated images
Colors don't match your vision
Realistic color palette, accurate skin tones, naturally saturated colors, photographically accurate, no oversaturation Use color temperature references:
Warm color grading, golden hour tones OR Cool color palette, blue-grey tones Reference specific colors:
Navy blue (#1B3A6B) suit, crisp white shirt, burgundy tie Request color correction:
Balanced exposure, professional color grading, neutral white balance, cinema-quality color
Harsh shadows or no shadows
Unnatural lighting directions
Inconsistent light sources
Be specific about light source and direction:
Soft natural lighting from large window on left side, gentle shadows, diffused light, golden hour quality Specify shadow characteristics:
Subtle soft shadows, realistic shadow placement, consistent light source, professionally lit Reference photography lighting:
Three-point lighting setup, studio photography lighting, key light from front-left, fill light from right, rim light from behind Request lighting consistency:
Unified lighting across entire scene, single consistent light source, realistic shadow placement
Uncanny valley effect
Asymmetrical faces
Odd expressions or features
Request authentic expressions:
Natural candid expression, genuine smile with authentic emotion, relaxed facial features, real person photography Specify photographic realism:
Shot with professional camera, realistic human features, natural skin texture, authentic portrait photography Reference real photography:
Professional headshot style, as if photographed by Annie Leibovitz, natural lighting, authentic human appearance No perfect symmetry, natural imperfections, realistic skin texture with pores, authentic human subject, not computer-generated appearance
Extra or missing fingers
Distorted hand shapes
Unnatural poses
Avoid hand close-ups initially: Hands are notoriously difficult for AI. Keep them small in frame or obscured when possible.
Hands resting naturally on lap, fingers relaxed, OR Hands clasped together in natural prayer position Reference real hand positions:
Holding coffee mug with handle between thumb and fingers, realistic hand grip, natural hand position Generate hands separately: If critical, generate the person first, then use local editing for hands with a new detailed prompt.
Hands in pockets, hands behind back, hands holding objects that obscure individual fingers Success Tip: Currently, hands remain one of AI image generation's biggest challenges. Plan compositions that minimize hand visibility for best results.

Too many failed attempts
Burning through credits quickly
Low success rate
Test with lower resolution first: Perfect your prompt at 1K before generating at 4K.
Use iterative refinement:
Basic prompt → check composition
Add style details → check aesthetic
Add quality keywords → final generation
