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