Picasa is a software application for organizing and editing digital photos, originally created by Idealab and owned by Google since 2004. "Picasa" is a blend of the name of Spanish painter Pablo Picasso, the phrase mi casa for "my house" and "pic" for pictures (personalized art).
Native applications for Windows XP, Windows Vista, Linux, and Mac OS X are available through Google Labs. For Windows 98 and Windows Me, only an older version is available. There is also an iPhoto plugin or a stand-alone program for uploading photos available for Mac OS X 10.4 and later.
Organization and editing
For organizing photos, Picasa has file importing and tracking features, as well as tags 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.
Keywords
Picasa uses picasa.ini files to keep track of keywords for each image. In addition to this, Picasa attaches 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 and Bridge), digiKam and iPhoto.
According to the Picasa Readme, Picasa can parse 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 in that displayed items are filtered as you type.
When a word is typed into the search bar, an image will be displayed if that word is all or part of a keyword, or part of the file name. If the search word is part of a folder name, all images in that folder are also displayed (but not necessarily images in subfolders, unless the word also exists in a keyword or filename.)
Picasa also supports boolean operators for searching in much the same way as Google's web search. All search terms are required by default (as with the operator "AND"), and images tagged with specified keywords can be excluded by using the hyphen (as in the boolean operator "NOT"). For example, searching for family children -friends will cause Picasa to display all images with the keywords family and children, but which do not include the keyword friends.
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.
