- * Modified 29 Oct 2002 (v1.2)
- * - Improved toSimpleString() to factor more complex rational numbers into
- * a simpler form
- * i.e.
- * 10/15 -> 2/3
- * - toSimpleString() now accepts a boolean flag, 'allowDecimals' which will

- * Created on 28 April 2002, 23:54
- * Modified 04 Aug 2002
- * - Renamed constants to be inline with changes to ExifTagValues interface
- * - Substituted usage of JDK 1.4 features (java.nio package)
- * Modified 29 Oct 2002 (v1.2)
- * - Proper traversing of Exif file structure and complete refactor & tidy of
- * the codebase (a few unnoticed bugs removed)
- * - Reads makernote data for 6 families of camera (5 makes)
- * - Tags now stored in directories... use the IFD_* constants to refer to the
- * image file directory you require (Exif, Interop, GPS and Makernote*) --
- * this avoids collisions where two tags share the same code
- * - Takes componentCount of unknown tags into account
- * - Now understands GPS tags (thanks to Colin Briton for his help with this)
- * - Some other bug fixes, pointed out by users around the world. Thanks!
- * Modified 27 Nov 2002 (v2.0)
- * - Renamed to ExifReader
- * - Moved to new package com.drew.metadata.exif
- * Modified since, however changes have not been logged. See release notes for

* Describes tags specific to Nikon (type 2) cameras. Type-2 applies to the E990 and D-series cameras such as the E990, D1,

+ *
* Thanks to Fabrizio Giudici for publishing his reverse-engineering of the D100 makernote data.
* http://www.timelesswanderings.net/equipment/D100/NEF.html
- *
+ *
* Note that the camera implements image protection (locking images) via the file's 'readonly' attribute. Similarly
* image hiding uses the 'hidden' attribute (observed on the D70). Consequently, these values are not available here.
- *
+ *
* Additional sample images have been observed, and their tag values recorded in javadoc comments for each tag's field.
* New tags have subsequently been added since Fabrizio's observations.
- *
+ *
* In earlier models (such as the E990 and D1), this directory begins at the first byte of the makernote IFD. In
* later models, the IFD was given the standard prefix to indicate the camera models (most other manufacturers also
* provide this prefix to aid in software decoding).
