MetaDataExtractor is a program/library that let you extract the metadata from your pictures. Your JPG files contain a lot of interesting information (meta data) like:
- the date
- the settings, flash, exposure time, program used ...
- and many more
An Example of how to use the library is available in the com.Run.cs
class. This code is inside the source release.
An other example is also available, since version 2.3.0c, as com.SimpleRun.cs

And of course, do not miss the ExifTool by Phil Harvey
