+ SUMMARY:
+ This script will correctly parse all of the EXIF data included in images taken
+ with digital cameras. It will read the IDF0, IDF1, SubIDF and InteroperabilityIFD
+ fields as well as parsing some of the MakerNote fields that vary depending on
+ camera make and model. This script parses more tags than the internal PHP exif
+ implementation and it will correctly identify and decode what all the values mean.
+
+ This version will correctly parse the MakerNote field for Nikon, Olympus, and Canon
+ digital cameras. Others will follow.
+
+ TESTED WITH:
+ Nikon CoolPix 700
+ Nikon CoolPix E3200
+ Nikon CoolPix 4500
+ Nikon CoolPix 950
+ Nikon Coolpix 5700

+
+ VERSION HISTORY:
+
+ 1.0 September 23, 2002
+
+ + First Public Release
+
+ 1.1 January 25, 2003
+
+ + Gracefully handled the error case where you pass an empty string to this library
+ + Fixed an inconsistency in the Olympus Camera parsing module
+ + Added support for parsing the MakerNote of Canon images.
+ + Modified how the imagefile is opened so it works for windows machines.
+ + Correctly parses the FocalPlaneResolutionUnit and PhotometricInterpretation fields
+ + Negative rational numbers are properly displayed
+ + Strange old cameras that use Motorola endineness are now properly supported
+ + Tested with several more cameras
+
+ Potential Problem: Negative Shorts and Negative Longs may not be correctly displayed, but I
+ have not yet found an example of negative shorts or longs being used.
+
+ 1.2 March 30, 2003
+
+ + Fixed an error that was displayed if you edited your image with WinXP's image viewer
+ + Fixed a bug that caused some images saved from 3rd party software to not parse correctly
+ + Changed the ExposureTime tag to display in fractional seconds rather than decimal
+ + Updated the ShutterSpeedValue tag to have the units of 'sec'
+ + Added support for parsing the MakeNote of FujiFilm images
+ + Added support for parsing the MakeNote of Sanyo images
+ + Fixed a bug with parsing some Olympus MakerNote tags
+ + Tested with several more cameras
+
+ 1.3 June 15, 2003
+
+ + Fixed Canon MakerNote support for some models
+ (Canon has very difficult and inconsistent MakerNote syntax)
+ + Negative signed shorts and negative signed longs are properly displayed
+ + Several more tags are defined
+ + More information in my comments about what each tag is
+ + Parses and Displays GPS information if available
+ + Tested with several more cameras
+
+ 1.4 September 14, 2003
+
+ + This software is now licensed under the GNU General Public License
+ + Exposure time is now correctly displayed when the numerator is 10
+ + Fixed the calculation and display of ShutterSpeedValue, ApertureValue and MaxApertureValue
+ + Fixed a bug with the GPS code
+ + Tested with several more cameras
+
+ 1.5 February 18, 2005
+
+ + It now gracefully deals with a passed in file that cannot be found.
+ + Fixed a GPS bug for the parsing of Altitude and other signed rational numbers
+ + Defined more values for Canon cameras.
+ + Added 'bulb' detection for ShutterSpeed
+ + Made script loading a little faster and less memory intensive.
+ + Bug fixes
+ + Better error reporting
+ + Graceful failure for files with corrupt exif info.
+ + QuickTime (including iPhoto) messes up the Makernote tag for certain photos (no workaround yet)
+ + Now reads exif information when the jpeg markers are out of order
+ + Gives raw data output for IPTC, COM and APP2 fields which are sometimes set by other applications
+ + Improvements to Nikon Makernote parsing
+
+ 1.6 March 25th, 2007 [Zenphoto]
+
+ + Adopted into the Zenphoto gallery project, at http://www.zenphoto.org
+ + Fixed a bug where strings had trailing null bytes.
+ + Formatted selected strings better.
+ + Added calculation of 35mm-equivalent focal length when possible.
+ + Cleaned up code for readability and efficiency.
+
+ 1.7 April 11th, 2008 [Zenphoto]
+
+ + Fixed bug with newer Olympus cameras where number of fields was miscalculated leading to bad performance.
+ + More logical fraction calculation for shutter speed.
