Google released free software for organising and finding the hundreds or thousands of digital photos often stored on users' hard drives.
Using technology developed by Picasa, which Google bought last year, the new software will try to make keeping a photo collection and editing pictures simple even for beginners, Picasa general manager Lars Perkins said.
Rather than requiring users to import individual photos from their drives, the Picasa software automatically detects them as they are added - whether sent via email or transferred from a digital camera.
Picasa tries to do away with complexities such as file names and folders. Photos are dumped into one bucket, sorted by date, but the software can quickly pull photos from date ranges or events as requested. In the new version, users will be able to mark the best pictures with a gold star and search only for those.
Picasa initially cost $US29 ($38) but became a free download after its acquisition by Google. Version 2 of Picasa will also be a free download.
The new software will have better tools for restoring colour and removing red eyes.
New editing features include the ability to make the sky bluer; to blur the background and focus on a subject; or to rotate photographs slightly to compensate for any camera tilt. All changes can be reversed, and the software stores different versions without requiring users to perform a "save as" command and rename the file.
Captions are automatically attached to the photo file so that they go with the photo to web sites and CDs.
Picasa is not Google's first venture onto the desktop. Though the company got its start as an internet search engine, Google released in October a desktop search tool that automatically records email, web pages and chat conversations and finds Word, Excel and PowerPoint files stored on the computer.
Picasa 2 is available only for Windows and requires Microsoft's Internet Explorer browser, version 5.01 or higher, or Mozilla Firefox.
