Eagle provides multiple ways for you to compare photos and view detailed information. Through plugins like "Image Comparison Tool," "Histogram," and "Exif Metadata," you can conduct in-depth analysis based on different needs. Here are the methods for installing and using these tools.

Installing Required Plugins

Click the "Plugins" button at the top of the Eagle toolbar
Select "Plugin Center"
Search for and install the following plugins:

Image Comparison Tool
Histogram
Exif Metadata

Image Comparison Tool

The "Image Comparison Tool" provides three different arrangement modes to help you precisely compare images:

Side by Side: Display two images horizontally side by side
Split: Show portions of each image in the same view
Overlay: Layer images on top of each other to easily spot subtle differences

These flexible viewing modes allow you to easily capture detail changes between similar images.

Histogram

The "Histogram" plugin provides professional image analysis data, similar to the histogram function in Photoshop. Through this plugin, you can instantly view:

Brightness distribution
Color distribution

This information is highly valuable for image editing and color adjustment, helping you make more precise decisions.

Exif Metadata

The "Exif Metadata" plugin is based on the excellent open-source technology Exiv2, allowing you to view detailed technical information about images without leaving Eagle, including:

Camera information
Shooting parameters
Geographic location (if available)

This is particularly useful for photographers organizing photo collections and analyzing shooting conditions.

Important Notes

Plugins need to be installed and run within the Eagle application
Some Exif information may vary depending on image format or shooting device
For batch analysis of large numbers of images, it's recommended to first filter out the images you need to examine in detail
