TTNview - a simple EXIF information viewer

What is TTNview?
TTNview is a simple viewer of EXIF information recorded by digital cameras in image files.
This information normally includes

shutter speed, aperture value (or F-stop), ISO sensivity;

Various camera settings, like white balance, program used, AE correction;

Camera maker and model;

Picture taking time and many other.

TTNview recognizes all standard EXIF tags and some proprietary formats of digital camera manufacturers. Here's the list of fields shown by this version:

Column Title	Description	Comments
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 can navigate directories and open files using their standard Windows associations.

In future, we plan TTNview to be able to do the following:

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. It will support EXIF 2.2 and maybe JFIF 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 - showing 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.

Features and advantages

All standard EXIF 2.1 tags supported for all camera vendors;

Proprietary formats (aka "Maker notes") decoded for:

Nikon cameras: white balance and ISO settings recognized;
Canon cameras: ISO setting;
Olympus cameras: white balance setting.

Information presented in consistent form, groupped by meaning into user-selectable columns; Tags of the same meaning are always shown in the same column, regardless of camera maker;

Smart data recognition: will try to analyze vendor-specific information only on cameras from that specific vendor; will never display non-sense data;

Full keyboard support;

Very fast; Will analyze thousands of files in seconds.
