- 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.
-

- Nikon CoolPix 700

- 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.
