NAA/IPTC Data

Previous | Index | Next

NAA/IPTC data is a method of storing textual information in images. It was developed for press photographers who need to attach information to images when they are submitting them electronically but it is useful for all photographers. It provides a standard way of storing information such as captions, keywords, location and captions. Because the information is stored in the image in a standard way this information can be accessed by other IPTC aware applications.

Downloader Pro can add IPTC data to the following types of images: JPEG, TIFF, Nikon raw files and Canon raw files.

Information about the IPTC standard for data stored in images files can be obtained from the IPTC's web site: http://www.iptc.org/IIM

Editing IPTC Data

You can edit the IPTC data by selecting "NAA/IPTC data..." from the edit menu or by typing Ctrl+C. Alternatively you can get Downloader to display the NAA/IPTC data dialog every time it is run (see General Preferences). Several sets of IPTC data can be prepared in advance and saved to disk by entering the data and pressing the "Save to file..." button. The data can then be loaded by pressing the "Load from file..." button.

The various IPTC data fields can contain fixed text or use the tokens below to automatically insert data extracted from the image.

The IPTC Data dialog is divided up into five different sections: Caption, Keywords, Categories, Credits and Origin. Click on the tabs along the top of the dialog to select the required section.

All the data fields under the Caption tab are free text entries.

Click on the Keywords tab to display the keywords. The keywords are displayed in the order they were entered (as opposed to alphabetical order) and each keyword must be unique. To add a new keyword enter the keyword in the text edit area at the top and either press the Enter key or the Add button. To delete a keyword first select it from the list then press the Delete button.

Click on the Categories tab to display categories. The main category is a free text entry. The supplemental categories are displayed in the order they were entered (as opposed to alphabetical order) and each one must be unique. To add a new supplemental category enter it in the text edit area at the top and either press the Enter key or the Add button. To delete a supplemental category first select it from the list then press the Delete button.

All the data fields under the Credits tab except for priority are free text entries. The priority is a number from 0, meaning "None", through 1 (meaning "High") to 8 (meaning "Low").

All the data fields under the Origin tab are free text entries except for the "Date Created" and "Release Date" fields. These must contain a date in the form YYYYMMDD where YYYY is the year including century (e.g. 2002), MM is the month (e.g. 03 for March) and DD is the day (e.g. 26). An optional : or / character may also be used to separate the year, month and date. Press the ">" button after "Date Created" to display a menu to set the date/time to the EXIF shooting date, the file creation date, the current time, yesterday, two days ago or select any date using the date/time dialog (shown below). Click on the ">" button after "Release Date" to set the release time to now, tomorrow, two days time, one weeks time, two weeks time or select any date using the date/time dialog.
