Picasa
Picasa is a software application for organizing and editing digital photos, originally created by Idealab and is owned by Google since 2004. "Picasa" is a mixture of Spanish painter Pablo Picasso's name, phrase casa for "my house noodles" and "pic" for pictures (personal art). In July 2004, Google acquired Picasa and began offering as a free download.On acquisition, the company's management team consists of Lars Perkins as CEO, Mike Herf as CTO, and Dan Engel as VP of original Pasar.Aplikasi Development for Windows XP, Windows Vista, Windows 7 and Mac OS X is available through Google Labs. For Linux Google has bundled with the Windows version to create the installation package instead of writing the original Linux version. For Windows 98, Windows Me and Windows 2000, the only available version is longer. There is also an iPhoto plugin or a stand-alone program to upload the photos are available for Mac OS X 10.4.
FEATURES:Organizing and EditingTo organize photos, Picasa has file importing and tracking features, as well as tags, face recognition, and collections for further sorting. He also offers some basic photo editing functions, including improved color, red eye reduction.Other features include a slide show, print images and timetable. Images also can be prepared for external use, such as for e-mail or print, by reducing the file size and page layout settings. There is also integration with online photo printing service.KeywordsPicasa uses picasa.ini files to track keywords for every image. In addition, Picasa attaches IPTC keyword data to JPEG files, but not for all other file formats.Keywords are attached to the JPEG files in Picasa can be read by other software such as Adobe Photoshop picture libraries Album, Adobe Bridge, digiKam, and iPhoto. According to the Picasa Readme, Picasa can parse XMP data. However, unable to find local files for existing XMP keywords.BrowsingPicasa search bar is always visible when viewing the library. Search that live in the items displayed will be filtered as you type. Search bar will search the file name, title, tags, folder names, and other metadata. Picasa also supports Boolean operators to search for in much the same way as Google web searches.All search terms are required by default (like the operator "and"), and images are marked with certain keywords can be excluded by using a hyphen (as in the boolean operator "no"). For example, searching for family child-friends will cause Picasa to display all images with the keyword "family" and "son", but does not include the keyword "friend". Picasa also has an experimental feature in the search box in which images can be searched for which contains a particular color with the color.ViewingPicasa does not have a separate window to display. There is only an "edit view" with the display area. Fullscreen view is available in slideshow mode, by pressing ctrl alt key while in "edit view", or by pressing the Alt Gr. This feature is also available through the Windows Explorer context menu, and give way to start the editor Picasa, too.BackupIn Picasa 2 and earlier versions, changes made in the image in Picasa overwrite the original files, but backup the original version stored in a hidden folder named "Original" in the same folder with the original picture. In Picasa 3, the changes made in Picasa image is saved to a file picasa.ini hidden in the same folder with the original picture. This allows multiple edits without changing the original image.Viewing pictures on Picasa or use Picasa Photo Viewer will apply modifications on the fly, while looking through other programs (like Windows XP's Photo and Fax Viewer) will display the original image. Changes can also be made permanent by using the "Save" function, where the original files are supported and the modified version is written in its place, similar to version 2.Face RecognitionOn 15 August 2006, Google announced it had acquired Neven Vision's technology that can be used to find features in images such as people or buildings. Google applied for face recognition technology and the function is launched on Picasa Web Albums on September 2 2008.Neven Vision incorporates several patent specifically centered around the face recognition from digital photographs and video images. Neven Vision technology is among the top finishers in both the FERET FRVT 1997 and 2002 independent tests comparing the best facial recognition technology in the world.GeotaggingSince June 2007 Picasa can write geographic coordinates for Exif metadata, so the photo geotagging. Google Earth must also be installed to do this. Since version 3.5 of Picasa, Google Earth is not required. Geotagging can be performed directly inside Picasa, Google Maps is more practical components, which enable this functionality in later versions of Mac OS X.
