Features


Organization and editing

For organizing photos, Picasa has file importing and tracking features, as well as tags, facial recognition, and collections for further sorting. It also offers several basic photo editing functions, including color enhancement, red eye reduction, and cropping. Other features include slide shows, printing, and image timelines. Images can also be prepared for external use, such as for e-mailing or printing, by reducing file size and setting up page layouts. There is also integration with online photo printing services. Other simple editing features include adding text to the image. Picasa supports Google's WebP image format as well as the JPG format and most

(RAW files). A user can view and edit RAW files and save the finished edit (as JPG, or other forms) without any changes to the original RAW file.


Keywords

Picasa uses picasa.ini files to keep track of keywords for each image. In addition to this, Picasa attaches IPTC Information Interchange Model (IPTC) keyword data to JPEG files, but not to any other file format. Keywords attached to JPEG files in Picasa can be read by other image library software like Adobe Photoshop Album, Adobe Bridge, Adobe Photoshop Lightroom, digiKam, Aperture, and

. According to the Picasa Readme, Picasa can parse Extensible Metadata Platform (XMP) data. However, it cannot search local files for existing XMP keywords.


Searching

Picasa has a search bar that is always visible when viewing the library. Searches are live, so that displayed items are filtered as one types. The search bar will search filenames, captions, tags, folder names, and other metadata. Picasa also has an experimental feature that allows searching for images that contain certain colors with the "color" operator.


Viewing

Picasa has no separate view window. There is only an "edit view" with a viewing area. Fullscreen view is available in slideshow mode, by holding down the ctrl+alt keys while in "edit view", or by pressing the Alt Gr key. This feature is also available through the context menu of Windows Explorer, and provides a way to start the Picasa editor as well.


Backup

In Picasa 2 and earlier versions, changes to pictures made in Picasa overwrite the original file, but a backup version of the original is saved in a hidden folder named "Originals" in the same folder as the original picture (.picasaoriginals on Mac OS X). In Picasa 3, changes to pictures made in Picasa are saved to a hidden file picasa.ini in the same folder as the original picture. This allows multiple edits to be performed without altering the original image. Viewing the picture in Picasa or using the Picasa Photo Viewer will apply modifications on the fly, whereas viewing through other programs (such as Windows XP's Photo and Fax Viewer) will display the original image. Changes can also be made permanent using the "Save" function, where the original file is backed up in a hidden folder .picasaoriginals located in the same folder as the original picture and the modified version is written in its place.


Face recognition

On August 15, 2006, Google announced it had acquired Neven Vision, whose technology can be used to search for features within photos such as people or buildings. Google applied this technology for face recognition, and this functionality was launched on Picasa Web Albums on September 2, 2008. Neven Vision incorporates several patents specifically centered around face recognition from digital photo and video images.


Geotagging

Since June 2007, Picasa can write geographic coordinates to Exif metadata, thus geotagging an image. Since version 3.5 of Picasa, geotagging may be done directly inside Picasa, in the Places panel. The geotagging functionality is described in the Picasa User's Guide.

According to the official website, the Hello project was shut down on May 15, 2008.


Discontinuation

On February 12, 2016, Google announced that the Picasa desktop application would be discontinued on March 15, 2016, followed by the closure of the Picasa Web Albums service on May 1, 2016.
