Examples
// Output all fields of current image to a memo (same as WriteTo)for i := 0 to _EXIF_Tag_Count - 1 do
memo1.Lines.Add( ImageEnView1.IO.Params.EXIF_FieldDescription[ i ] + ': ' + ImageEnView1.IO.Params.EXIF_AsStr[ i ] );
// Set EXIF_ShutterSpeedValue to 1/4 a second
ImageEnView1.IO.Params.EXIF_AsStr[ _EXIF_ShutterSpeedValue ] := '1/4';
