The Digital Photographer's Software Guide
Most image viewers provide facilities to read a truncated version of Exif data, but once
you install a program such as ExifTool you will see the full extent of the data recorded
automatically by the camera. To write Exif data you need special software, such as that
described here, or what’s included with image handling and cataloging software.
Professional photographers also use IPTC metadata, defined by the International Press
Telecommunications Council, to identify the copyright holder and other information
about the image. The latest version uses Adobe’s “Extensible Metadata Platform” (XMP)
to embed the data into JPEG, TIFF, JPEG 2000, GIF, PNG, HTML, PostScript, PDF,
SVG, Adobe Illustrator, and DNG files. A good product for inserting and editing IPTC
metadata is the IMatch image management tool (see Chapter 5, “Cataloging”).
ExifPro Image Viewer
Vendor: Michal Kowalski
Purpose: An image viewer that pays especial attention to preserving and presenting Exif data
Description
ExifPro Image Viewer allows you to display, manipulate, and browse photographs in
different view modes, as well as pay especial attention to the Exif data embedded in
JPEG photographs. The project to develop it grew out of the earlier (and free) EXIF
Image Viewer that displayed Exif data for comparative purposes together with an image
histogram. The new version is more elaborate, as it can append not only IPTC file information
but also GPS information showing longitude/latitude location. ExifPro is a genuine
image browser with copying and resizing tools and a side-by-side display facility.
Note: it does not decode RAW images but extracts embedded JPEGs.
Comments
Michal Kowalski has created a terrific utility in ExifPro Image Viewer and continues to
keep it up-to-date by adding XML support. His Website (especially the Help section)
is a model of clarity that puts many corporations to shame.

Despite being a standard, Exif allows different manufacturers to place their own custom
format metadata into a section of the file called the makernote tag. Canon, Nikon,
and others can use this to encode really useful technical information about focusing
