MATLAB Application to Scan All Metadata from Pictures and Exporting Them to Excel Sheet | Photo Metadata Scanner

admin — Sun, 19 Jan 2025 16:49:25 +0000

We are happy to introduce our new MATLAB app specialized in extracting metadata from photos. This application is designed using MATLAB AppDesigner Framework and can be used by professional photographers or curios individuals who want to know the settings behind each picture!

If you are a beginner or intermediate in photography and want to improve your skills, then one of the best ways to practice is by studying other photographers’ photos. That is, learning from their skills!

One of the skills that needs to be acquired is understanding the suitable settings used in each picture and in each scene. The word “settings” is, of course, broad! What we are trying to say here is knowing the camera manufacturer, camera type, shutter speed, aperture value, f-number (or f-stop), light source, flash mode, focal length, white balance, exposure mode, digital zoom ratio, contrast, saturation, sharpness, subject distance range, etc.

The scanned metadata is categorized under four groups:

General Information
Digital Camera
Exif Thumbnail
Unknown Tags

The “General Information” group is responsible to display the following metadata:

Filename
File Modification Date
File Size
Format
Format Version
Width
Height
Bit Depth
Color Type
Format Signature
Byte Order
New Sub-File Type
Bits Per Sample

Once the scanning process of all the available image metadata is complete, the extracted metadata can be exported as MS Excel sheet (as shown below), so the photographer can refer to it any time later.

This metadata scanning tool is a great app not only for analyzing photographs but also for reporting, documenting, and fraud investigation.
