Frequently Asked Questions

Common questions about using EXIF Analytics

🚀 Basic Usage

Which photo formats are supported?

EXIF Analytics supports the following photo formats:

JPG/JPEG: Most common photo format, fully supported

💡 It is recommended to use JPG format for best compatibility and speed.

Why can't some photos be parsed for EXIF data?

Common reasons for EXIF data not being parsed:

EXIF data missing: EXIF may be removed after uploading to social media or editing
Unsupported format: Some special formats or compressions may not contain standard EXIF
File corruption: The photo file is damaged
Privacy settings: Some cameras/phones are set not to record EXIF

⚠️ Photos saved from WeChat, QQ, etc. usually have no EXIF data.

How many photos can be analyzed at once?

There is no strict limit, but for best performance:

Recommended: 100-300 photos per batch
Maximum: Up to 500 photos
Performance: Too many photos may slow down the browser

💡 For large numbers, analyze in batches for better organization and performance.

⚡ Features

How does smart filtering work?

Smart filtering works by:

Auto recognition: Detects camera and lens models
Auto grouping: Groups photos by device
Parameter filtering: Filter by ISO, aperture, shutter, etc.
Combined filters: Multiple conditions can be used together

💡 Filters affect charts and reports in real time.

Why do phone photos show "Unknown Lens"?

This is normal because:

Design difference: Phones usually do not record lens info in EXIF
Standard difference: Phone EXIF standards differ from cameras
Smart handling: The system recognizes devices, other parameters are not affected

💡 Other parameters (ISO, focal length, etc.) can still be analyzed for phone photos.

How accurate is the analysis report?

The report is based on EXIF data:

Data source: Reads technical parameters directly from camera
Statistics: Uses professional algorithms for scientific results
Insights: Based on photography theory and data patterns

💡 Results reflect your shooting habits for the analyzed period.
