Many professional (and serious amateur) photographers use the IPTC (International
Press Telecommunications Council) Standard to encode their photograph image files
with descriptive information. Originally designed for use by news agencies
when transmitting news story images, IPTC includes such items as Caption/Headline,
Description/Comments, Creator/Byline, Copyright, Keywords, etc. Phota
provides convenient access to this data from the Photo Information
screen. Image files (JPEG, TIFF,
PNG, PSD and DNG formats) encoded with either the legacy IPTC IIM Standard or the
more recent IPTC Core XMP Standard will be recognized.
Image files might also contain encoded EXIF (Exchangeable Image File Format)
data. EXIF information is often stored within image files created by digital
cameras, and includes technical parameters that describe the photograph, such as
Camera Make and Model, Date and Time Taken, Image Width and Height, Aperture, etc.
It is also possible to load album Photo Description items from relevant
IPTC and EXIF fields according to specifications defined via the Photo Image
Data Mapping screen. Both the Photo Information and the
Add Photos screens include
options for loading from stored IPTC/EXIF image data.
