What is TTNview?
size of the file in bytes;
aperture value, or F-stop;
White balance settings;
TTNview is a simple viewer of EXIF information recorded by digital cameras in image files.
Currently, TTNview will show just what you see on the picture above, i.e.:
TTNview can currently navigate directories and open files using their standard Windows associations.
In future, we plan TTNview to be able to do the following:
show various exif information including camera-specific information from various vendors;
be modular and extensible: support new cameras and new tags without re-compiling the program;
show images and thumbnails;
do basic image manipulations: rotate, crop, negative, b/w;
remember preferred image position in order to view vertical images as vertical, without modifying the image file;
do basic file manipulations: copy, move, delete;
TTNview is free.
TTNview is built in accordance with EXIF 2.1, and it will support EXIF 2.2 in its future releases.
We wrote TTNview for fun. It is a nice programming practice and a lot of pleasure. In addition to its primary goal - show EXIF information - we want to use TTNview as a platform for testing different programming techniques and usability ideas.
We want to make TTNview the fastest possible image analyzer and we'll optimize any place where we see optimization possible.
TTNview is also planned to be very usable, though laconic in its GUI. It is going to be simple and understandable. We will develop it in tight conformance with Windows GUI standards and we'll conduct usability tests. The viewer supports and will support mouse users as well as keyboard users.

New in this version
Added support for files with Intel byte order. The meaning is that standard EXIF tags (speed, F-Stop, ISO, etc.) are now supported in all cameras that write them.
Added support for Nikon's and Canon's maker note. ISO and white balance information is now displayed for most Nikon cameras (not yet for D100); ISO setting is now displayed for most Canon cameras.
JPEG files with no EXIF information are now displayed with empty frame icon.
Limitations of this version
Only JPEG files are currently analyzed - TIFF is not yet supported;
Selecting which columns to show. We currently recognize most EXIF tags (51 of them, to be exact) and only show five of them. We'll let the user choose which fields (s)he would like to see. Thus the user will be able to select any number of columns in order to see any information required (focus length, zoom setting, exposure bias value, etc.)
Saving settings and remembering last directory browsed.
In the nearest future:
And after that:
Viewing images and image thumbnails
