Download latest version of TTNview from http://myalpha.dls.net/ttnview
TTNview is a single executable file. After downloading, place it wherever you like on your hard disk. You can then create a shortcut to it in the start menu or on the desktop. Alternatively, you can put it into a directory contained in your PATH to be able to call it from Windows' Run dialogue just by typing "ttnview".
The directory where you place ttnview.exe must be allowed to write. Otherwise, TTNview will work, but will not be able to save column settings.
Run ttnview.exe from the directory where you placed it. TTNview will show you an empty window. To start working, you have to open a directory containing some files.
TTNview allows you to choose which columns to see. Currently, there are 13 columns to choose from. On first run, TTNview will display all columns.
To choose columns:
After making changes in columns set, TTNview will re-read the current directory to fill the new set of columns.
Saving columns set
After you modify the set of columns to view, you can save this set to see it on next run of TTNview.
To save columns set,
TTNview writes a file with settngs into the same directory where ttnview.exe resides. If the directory is not allowed to write, you'll get an error message.
If you don't save column settings, TTNview will prompt you to do so on exit.

EXIF informaiton presented
EXIF columns meaning is described below:
|Speed||Shutter speed, aka exposure time, seconds||Either a fraction of a second (like 1/250) or a number of seconds (like 2")|
|F-Stop||Aperture value, aka F-Stop||The value is the fraction of the Focus Length, e.g. value of 11 means the aperture was F/11||ISO||Camera sensor sensivity, in ISO units, similar to film sensivity||Some Nikon and Canon cameras use proprietary format for this setting. In files from those cameras, the value may be missing if they were processed by a software that only preserves standard tags||WB||White Balance setting aka Color Mode, aka Color Temperature; Similar to kind of film (daylight, incadescent, etc).||This setting is currently analyzed for Canon, Nikon and Olympus cameras only. The actual value depends on how the manufacturer calls the respective setting||Maker||Camera maker||Model||Camera model||AE +/-||Automatic Exposure (AE) compensation, aka Exposure Bias. The value is a correction applied by the user to the exposure selected by the camera. The value is measured in photographic "steps" aka EV.||For example, +0.25 means a quarter of the step brighther, -1 means one step darker. "none" - no correction applied||Time Shot||Time when the picture was shot||This field is expected to be always preserved by processing software||Time Digitized||Time when the picture was digitized||Focal Length||Focal Length of the camera lens; For zoom lenses - the Focal Length used for this picture||The value is in millimeters. In this version, the value is not converted to 35mm equivalence||Flash||Flash - just "Fired" or "Not fired"||This does not depend on flash setting on camera (Auto/On/Off/Red-eye/Slow Sync, etc). For example, if the flash was set to ON, but was not fired because it was not fully charged, the value will be "Not fired".||AE Program||Automatic Exposure (AE) program. Some cameras just call it "Mode". Determines how the camera chooses the exposure (Program, Aperture Priority, Shutter Priority, Manual and the like)||Metering||Metering mode. Which part of the frame is used to measure the exposure. Average, Center-Weighted, Spot and the like|
TTNview writes a file with settngs into the same directory where ttnview.exe resides. If the directory is not allowed to write, you'll get an error message. In this case, the only way to quit the program is to answer "No" to the question.
