Our facial recognition technology identifies people in your photos and intelligently organizes them for better storytelling.

How Face Recognition Works

1. Face Detection: System scans each photo to identify human faces using advanced neural networks
2. Feature Mapping: Creates unique facial feature "fingerprints" for each detected face
3. Person Clustering: Groups photos containing the same person together
4. Smart Positioning: Ensures faces are never cut off or placed in page gutters
5. Prominence Adjustment: Sizes portrait photos appropriately based on number of faces

Face Recognition Benefits

Feature	What It Does
Person Grouping:	Automatically clusters photos by individual
Face Protection:	Prevents faces from being cropped or hidden
Portrait Priority:	Places photos with faces prominently
Group Detection:	Identifies group photos vs solo portraits

💡 Pro Tip: For best face recognition results:

• Use photos where faces are clearly visible (not obscured by sunglasses, hats, or shadows)
• Ensure adequate lighting on faces
• Include multiple photos of the same person for better accuracy
• Avoid extreme angles or profile shots for key subjects

Privacy & Data Security

🔒 Your Privacy Matters:
• Facial recognition data is temporary and used ONLY during book creation
• All facial data is automatically deleted after your project is complete
• We never store facial recognition information permanently
• Your photos are never used to train AI or shared with third parties

AI automatically identifies and manages duplicate or nearly identical photos to keep your photo book clean and focused.

Types of Duplicates Detected

1. Exact Duplicates
2. Near Duplicates
3. Burst Photos
4. Edited Versions

⚠️ Review Before Finalizing: Always check the "Unused Photos" before ordering. AI might have excluded photos you want to include. You can easily add them back with one click.

AI analyzes photo content to understand what type of scene each image contains, enabling smarter organization and layout decisions.

90° Increments	Click "Rotate Left" or "Rotate Right" buttons	Fixing orientation (portrait vs landscape)
Fine Adjustment	Use rotation slider (0-360°) or enter specific angle	Straightening horizons, creative angles

Enhance photos directly in the editor without external software:

• Brightness: -100 to +100 (fix underexposed or overexposed photos)
• Contrast: -100 to +100 (add punch to flat photos)
• Saturation: -100 to +100 (boost or mute colors)

💡 Photo Editing Tips:

• Make subtle adjustments - extreme edits look artificial
• Apply same adjustments to photos from same event for consistency
• Use "Reset" button if you go too far - restores original
• For major editing (removing objects, advanced retouching), edit in external software before upload

What is a Color Scheme?

A color scheme is a harmonious palette of 3-5 colors used consistently throughout your photo book for backgrounds, text, borders, and embellishments. Proper color schemes create visual unity and professional polish.

Color Scheme Types

Scheme Type	Description	Best For
Monochromatic	Variations of single color (light to dark)	Elegant, cohesive designs with subtle sophistication
Analogous	Colors next to each other on color wheel (e.g., blue, teal, green)	Nature themes, harmonious and calming designs
Complementary	Opposite colors on wheel (e.g., blue & orange)	Bold, dynamic designs with high visual impact
Triadic	Three colors evenly spaced (e.g., red, yellow, blue)	Vibrant, playful designs for kids or celebrations
Neutral	Black, white, gray, beige tones	Classic, timeless designs that won't distract from photos

Color Psychology Guide

Color	Emotion/Meaning	Best Use
Blue	Trust, calm, serenity	Beach vacations, peaceful moments, professional books
Green	Nature, growth, harmony	Outdoor adventures, eco-themes, spring/summer events
Red	Passion, energy, excitement	Romantic occasions, celebrations, bold statements
Orange	Warmth, enthusiasm, creativity	Autumn themes, energetic events, family fun
Purple	Luxury, elegance, spirituality	Weddings, milestone celebrations, sophisticated designs
Yellow	Joy, optimism, sunshine	Happy occasions, summer vacations, children's books
Black/Gray	Sophistication, timelessness	Classic designs, black & white photography, formal events

⚠️ Color Scheme Cautions:
• Too many colors create visual chaos - stick to 3-5 max
• Ensure text remains readable on colored backgrounds
• Bright neon colors can look garish in print - test with preview
• Consider recipient preferences (e.g., avoid pink for non-feminine themes)
• Colors appear slightly different in print vs screen - order sample if uncertain

Design Best Practices

Follow these professional guidelines to ensure your photo book looks stunning in print.

Photo Resolution Guidelines (DPI Requirements)

Understanding DPI (Dots Per Inch)

DPI measures print resolution. Higher DPI = sharper, more detailed prints. Too low DPI = blurry, pixelated results.

📐 PRO LAB Print Standard: 300 DPI
This professional lab-quality standard ensures crisp, sharp photos that look their best in your photo book.

Minimum Resolution by Product Size

Photo Book Size	Full Page Photo	Half Page Photo	Quarter Page Photo
6x8" Book	1800 x 2400 px	1200 x 1800 px	900 x 1200 px
8x8" Book	2400 x 2400 px	1600 x 1600 px	1200 x 1200 px
10x10" Book	3000 x 3000 px	2000 x 2000 px	1500 x 1500 px
12x12" Book	3600 x 3600 px	2400 x 2400 px	1800 x 1800 px
12x16" Lay Flat	4800 x 3600 px	3200 x 2400 px	2400 x 1800 px

⚠️ Common Resolution Mistakes:
• Social media downloads: Instagram/Facebook compress images (often 1080x1080px) - too small for full-page use
• Screenshots: Screen resolution (72-96 DPI) is too low for print
• Email attachments: Often downsized for email - use original files instead
• Over-cropping: Aggressive cropping reduces effective resolution

How to Check Photo Resolution

On Windows:

1. Right-click photo file → "Properties"
2. Click "Details" tab
3. Look at "Dimensions" (e.g., 4000 x 3000 pixels)
4. Compare to table above for your intended use

On Mac:

1. Select photo file
2. Press Cmd + I (Get Info)
3. Expand "More Info" section
4. Look at "Dimensions" field

Technical Quality Factors

Factor	Good	Bad
Focus	Sharp, clear details throughout	Blurry, out-of-focus, motion blur
Exposure	Well-lit, balanced brightness	Too dark (underexposed) or too bright (overexposed)
Noise/Grain	Smooth, clean image	Grainy, speckled (common in low-light phone photos)
Color Balance	Natural colors, neutral whites	Orange/blue color casts, unnatural tones
Compression	Minimal artifacts, smooth gradients	Blocky, pixelated, strange artifacts

Improving Photo Quality

✓ DO THIS

• Use original files from camera
• Shoot in good lighting
• Keep camera steady (avoid shake)
• Use camera's highest quality setting
• Export from editing software at 100% quality
• Transfer photos via USB/cloud (not email)

✗ AVOID THIS

• Using photos downloaded from social media
• Taking photos in very dark environments
• Using heavy digital zoom
• Saving photos multiple times (quality loss)
• Aggressive filtering/over-editing
• Using screenshots as photos

💡 Pro Tip - Test Print: If uncertain about photo quality, order a small size print first as a "proof." This lets you see actual print results before committing to expensive large format or lay flat albums.

The Golden Rules of Layout Design

1. Visual Hierarchy

Lead viewer's eye with intentional sizing. Most important photo = largest. Supporting photos = smaller.

2. Breathing Room

Don't cram every inch. White space (negative space) gives eyes rest and makes photos stand out more.

3. Visual Rhythm

Vary layouts page-to-page. Alternate between full-bleed pages and collages for dynamic flow.

4. Balance

Distribute visual weight evenly. If left side is heavy with large photo, balance right with text or smaller photos.

5. Consistency

Maintain cohesive style. Use similar layout patterns within chapters for professional look.

6. Storytelling

Arrange photos to tell story. Start with establishing shots, build to key moments, end with conclusions.

Page Layout Patterns

Pattern	Description	Effect
Full Bleed Hero	One stunning photo fills entire page	Maximum impact, perfect for best photos. Use sparingly for dramatic effect.
Grid Symmetry	Equal-sized photos in perfect grid	Clean, organized, modern. Great for showing progression or series.
Feature + Supporting	One large photo + 2-4 smaller photos	Highlights key moment while providing context. Most versatile pattern.
Alternating Sizes	Large-small-large-small rhythm	Creates dynamic visual flow. Prevents monotony.
Panoramic Spread	One photo spans two pages (Lay Flat only)	Epic landscapes or group photos. Showstopper effect.

Layout Mistakes to Avoid

Common Layout Errors:

❌ Gutter-Split Faces: Never place faces in center gutter on standard binding books
❌ Tiny Photos: Photos smaller than 2"x2" lose impact - combine with others or remove
❌ Cluttered Pages: More than 8 photos per page feels chaotic
❌ Inconsistent Borders: Mixing bordered and borderless photos randomly looks messy
❌ Text Overload: Long paragraphs compete with photos - keep text concise
❌ Poor Alignment: Photos not aligned to common edges look amateur

Where to Place Text

✓ GOOD PLACEMENT

• Below photos as captions
• In solid color areas of photo (sky, grass)
• On dedicated text pages between photo sections
• In margins with adequate padding
• On semi-transparent overlay boxes

✗ POOR PLACEMENT

• Over faces or important subjects
• In busy/detailed areas (hard to read)
• Too close to page edges (may get trimmed)
• In center gutter (gets lost in binding)
• Overlapping multiple photos

Text Sizing Guidelines

Text Type	Minimum Size	Recommended Size	Maximum Length
Cover Title	24pt	36-48pt	30 characters
Chapter Headings	18pt	24-32pt	50 characters
Photo Captions	10pt	11-14pt	100 characters
Body Text/Stories	10pt	11-12pt	500 characters
Dates/Small Details	8pt	9-10pt	50 characters

Text Contrast & Readability

💡 Readability Rules:

High Contrast is Key: Text must contrast sharply with background
• Light backgrounds → Dark text (black, dark gray, navy)
• Dark backgrounds → Light text (white, cream, light gray)
• Color photos → Use semi-transparent box behind text

Test Readability: Zoom out in editor. If you can't read text easily, neither can viewers.

Text Overlay Techniques

Semi-Transparent Box

Place text on colored box with 50-80% opacity. Box provides contrast without blocking photo entirely.

Gradient Overlay

Apply gradient that darkens (or lightens) area behind text. Creates smooth, professional look.

Drop Shadow

Add subtle shadow behind text. Works when text overlays moderately busy photos.

Stroke/Outline

Add thin contrasting outline around text. Works for bold, display fonts only.

Bleed & Safe Zones Explained

What is Bleed?

Bleed is the extra area beyond the finished page size where photos/backgrounds extend. During printing, pages are cut slightly inside bleed zone to ensure no white edges appear.

Page Zones Diagram

■ Black Border: Trim Line (actual page edge)
■ Blue Zone: Bleed Zone (extends 3mm beyond trim)
■ Red Zone: Total Print Area (bleed + page)
■ Green Zone: Safe Zone (5mm inside trim)

The Three Zones

Zone	Purpose	What Goes Here
Bleed Zone (3mm beyond page)	Prevents white edges from slight cutting variations	Background colors, edge-to-edge photos. Nothing critical.
Trim Zone (Actual page edge)	Where page will be cut	Full-bleed photos extend here, but avoid text/faces.
Safe Zone (5mm inside edge)	Guaranteed never to be cut	All text, faces, important details must stay inside.

Bleed Best Practices

✓ DO:
• Extend background colors/patterns into bleed zone
• Let edge-to-edge photos bleed off page
• Keep all text at least 5mm from page edge
• Keep faces and important subjects well inside safe zone

✗ DON'T:
• Place text in bleed zone (will be cut off)
• Position faces near page edges (might get trimmed)
• Leave white gaps at edges (looks unprofessional)
• Worry about bleed lines - they're hidden in final print 💡 PRO LAB Makes Bleed Easy: Our editor automatically shows safe zones and warns if text/important elements are too close to edges. Blue guidelines appear when dragging elements near danger zones.

Special Bleed Considerations

• Lay Flat Albums: No center gutter means seamless panoramic spreads - bleed zones matter less in center, more at outer edges
• Hardcover vs Softcover: Hardcover has slightly larger safe zone due to rigid binding
• Spine Width: Books over 60 pages have wider spines - affects center gutter placement

Low-Resolution Photo Warnings

Understanding the Warning

When you see a low-resolution warning, it means the photo doesn't have enough pixels for the size it's being printed at. This results in blurry, pixelated prints.

⚠️ "This photo is low resolution and may print blurry"
This warning appears when photo resolution is below 200 DPI for its current size in layout.

Solutions for Low-Resolution Warnings

Option 1: Use Smaller Layout

1. Keep the photo but reduce its size on page
2. Move photo to smaller frame in layout (e.g., from full-page to quarter-page)
3. Smaller print size = warning disappears
4. When to use: Photo is important but slightly low quality

Option 2: Replace with Higher Quality Version

1. Find original high-resolution file (camera SD card, cloud backup)
2. Avoid using social media downloads - always too compressed
3. Right-click photo → "Replace Photo"
4. Upload higher quality version
5. When to use: You have access to better quality file

Option 3: Remove Photo

1. If photo will print poorly and can't be fixed, remove it
2. Better to have fewer great photos than include blurry ones
3. Adjust layout to work without this photo
4. When to use: Photo quality is unacceptable and no alternatives exist

Preventing Low-Resolution Issues

💡 Prevention Tips:
• Always upload original files from camera (not edited copies)
• Avoid downloading photos from Instagram/Facebook - use originals
• Transfer photos via USB/cloud, not email (email compresses)
• Check resolution before upload using our guidelines above
• When in doubt, include photo in upload - editor will flag if problematic

Photo Upload Errors

Common Upload Error Messages

Error Message	Cause	Solution
"File format not supported"	Photo is in unsupported format (GIF, BMP, WebP)	Convert to JPEG using free online converter or photo editing software
"File too large"	Photo exceeds 25 MB limit	Compress photo or resize to 6000x6000px max (maintains quality for any print size)
"Upload failed - connection error"	Internet connection interrupted	Check WiFi, try again, or upload in smaller batches (50 photos at a time)
"Cannot read file"	File is corrupted or incomplete	Try re-exporting photo, or use different copy from backup
"Upload limit exceeded"	Trying to upload more than 500 photos at once	Upload in batches of 500 or fewer

Upload Troubleshooting Steps

1. Check Internet Connection: Ensure stable WiFi (minimum 5 Mbps upload speed)
2. Clear Browser Cache: Browser → Settings → Clear browsing data → Cached images and files
3. Disable Browser Extensions: Ad-blockers and privacy extensions can interfere - disable temporarily
4. Try Different Browser: If Chrome fails, try Firefox or Edge
5. Reduce Upload Quantity: Instead of 200 photos, try 50 at a time
6. Check File Names: Avoid special characters (& % $ # @) in filenames - use letters, numbers, dashes only
7. Update Browser: Ensure you're using latest version
8. Restart Computer: Simple reboot often fixes weird upload issues

⚠️ Upload Stuck at 99%?
This usually means the upload completed but processing is slow. Don't refresh! Wait 2-3 minutes. If still stuck, refresh page and check if photos appear in library - they likely uploaded successfully.
