Picasa helps you organize your photographs the way you want to. You can create groups of photos as albums. When the photographs are initially imported it is saved in the same structure as in your hard disk or digital camera. Once you create albums, you can play around with the photos without affecting the original photos. It simply means even if you delete an album your original photos remain intact.
Labeling and Grading Photographs
You can create sects and sub-sects of photographs. In simple words you can label your photographs without changing the original folders. You can also grade your photographs according to any criteria that you assign. The grading is based on the number of stars.
Editing the Photographs
For beginners this tool is a blessing.Basic editing functions include cropping, coloring, filling and auto coloring the photographs. You can also create effects in a photograph like sharpening or brightening.
Another feature under the edit tool is tuning of photographs which allows you to work around with adjusting the contrast or removing unwanted colors. It also has an I am feeling lucky button similar to the parent Google page which simply edits the photographs what it thinks is the best. Probably the best feature of Picasa is that any changes you make to a photograph with the editing tool are saved in a reversible format. This allows you to keep editing without saving different files.
Picasa utilizes a simple folder system to organize photographs. The editing features, though good for amateurs is limited. It does not allow you to do much. The biggest disadvantage in the editing tool is that there is no way you can edit the date on a photograph if there is one. The best features of Picasa include the easy and almost automatic digital storage and the ability to share photos with friends without exposing your photos to the entire world!
