May 22, 2012 (FPRC) -- The Exchangeable image file format or Exif is a specification of file format for images used by digital cameras. Exif Viewer is a new software that is compatible with the Exif standard. It displays all the Exif data of an unlimited number of images, which makes it one of the most powerful tools for professional and amateur photographers.
Metadata tags defined in the standard Exif format cover a wide range of data, including:
- The date and time - digital cameras record the date and time of shooting and insert it in the metadata.
- Settings of the device. This includes static information such as the make and model of the camera and variable information such as orientation, opening, shutter speed, focal length and sensibility
- Geographical information from any GPS system connected to the device. In 2008, more and more devices support this function. Some photographers use a classical system to locate their movements and then manually add geographic coordinates metadata corresponding to the temporal data of photography.
- Description, comments and copyright information.
This data is incorporated into the header of the image file itself and can be recorded by the majority of current digital cameras.
To view this information, you need a software that is compatible with the Exif standard.
Exif Viewer is a powerful freeware that allows to read the data simply by loading the image files. The software displays then exposure, the opening, exposure time, the selected program mode, ISO equivalent, flash info and a lot of other information. The data can be valuable when it comes to understand why a picture is missed, or when it comes to modify a parameter in order to improve the shot. It is therefore an indispensable tool for any professional and amateur photographer.
Most of the software do not retain all the EXIF information included in the image files. Note for example the following cases:
- Importing in Raw Camera mode in Photoshop of a Canon's CR2 loses information on the focal length of the objective.
- When a Nikon's NEF file is imported by Nikon Editor or Nikon View NX, the date of the shooting is replaced immediately by the date of editing, which hides the original date of the photo.
However Exif Viewer is able to display all the data, not only on a single file but on a set of photos. Its intuitive interface allows to sort the information and change their insertion and order, to allow the user to select only the data they may need.
