title: Copying EXIF from 1 image to another is failing
body: <p>I am using something like this:</p>
  
  <pre><code>foreach (PropertyItem item in image.PropertyItems)
  {
      newImage.SetPropertyItem(item);
  }
  </code></pre>
  
  <p>But it is not copying all the EXIF elements. A number of the core "good ones" are missing, like Camera Make and Camera Model. What is causing this?</p>
  
  <p>I would consider using a 3rd party component or libray. But I need it to be free and it has to be able to write EXIF data, as well as extract it.</p>
