For greater control over the image, click the Tuning tab. The Tuning tab enables you to use sliders to adjust Fill Light, Highlights, Shadows, and Color Temperature (the third tab, Effects, provides a dozen special effects). By using the Tuning tab, we achieved better color and exposure.
Once you make changes to a RAW file, the changes are stored in Picasa, but the RAW file itself is not changed.
If you have a number of RAW images that have the same color temperature (white balance) or exposure problems, or if you want to apply the same special effects to a group of photos, you may want to make the same edits to each photo. Here's how Picasa does it.
1. Select the fixes desired from the Basic Fixes, Tuning, and Effects tab.
2. Click Edit, Copy All Effects.
3. Click Back to Library.
4. Use Shift-click or Ctrl-Click to select similar photos.
5. Click Edit, Paste All Effects.
Unfortunately, because you pasted the effects to the files, the sliders used to adjust exposure, color temperature, and effects do not show the actual settings on the target files.
To create a JPEG file (which can be used for printing, emailing, websites, and so on) from your edited RAW file, click File, Save As, and select JPEG from the pull-down options. Unfortunately, Picasa does not provide options for file size/quality.
Picasa matches the image quality of the original photo, and uses a quality level of 85% when it cannot determine the quality level.
If you need to convert a RAW file into a file type other than JPEG, current versions of Picasa can't do it (this feature was available in earlier versions).
Pros: Free, supports most cameras that shoot RAW images, easy to use interface
Cons: Automatically makes changes to photos that can't be undone, more limited controls than others, can only export photos in JPEG, can't control JPEG quality levels.
Our take: Use Picasa 3.5 if it's all you have, but you'll probably be happier with your camera vendor's RAW image editor, or with Adobe Photoshop Elements with Camera RAW.
