If you have Photoshop Album 2.0 (PSA2), do you need to uninstall it before installing Photoshop Elements 3.0 (PSE3), which includes Album functionality as part of the application? (This is on Windows only, BTW) The answer is NO, and, in fact, PSE3 does a nice job of importing/converting/using PSA2's catalog so that you don't lose any of your tags, collections, etc. Also, you don't need to uninstall Photoshop Elements 2.0, but it's not a bad idea (I've seen some interesting behavior with both apps launched).
If you are considering buying Photoshop Elements 3.0 (PSE3) or spending the additional $30-40 to get the Photoshop Elements 3.0/Premiere Elements 1.0 (PRE1) bundle, buy the bundle! Most digital cameras also shoot video and having the option to create movies and burn DVDs to share using both images and video is pretty tantalizing. To tempt you further, if you purchase the bundle, there are features in PSE3 that are 'activated' when PRE1 is installed. For instance, in addition to the ability to burn your creations to a VCD (video compact disc) you will be able to burn your creations to a DVD with a menu.
If you are trying to install PSE3 on a Mac and the installer quits and you get the following error after entering your username and password: “There were errors installing the software, please try installing again,” try disabling all fonts through FontBook. This should allow for a successful installation.
If you have a bunch of original images and you want to apply a Watermark to them, enabling you to share them while protecting them from misuse, here is your solution. After you have launched Photoshop Elements 3.0, click on the File menu --> Process Multiple Files… In this dialog box, you have lots of options for processing a group of images, from renaming and resizing to converting to a different file format. To add your personal Watermark to all images, expand the Labels drop down triangle and there you have all your Watermark settings. Process away!
If you have installed Photoshop Elements 3.0 and do not have Acrobat Reader installed on your system, listen up. There are some features in PSE3 that call on the Reader to be used to preview your files. When you are prompted to “Preview your creation,” nothing will happen. Elements won't tell you that Reader needs to be installed or that it couldn't find an application to use to preview. Adobe is betting that you already have Acrobat Reader on your system. If you don't, they make it easy to be sure you do, by providing it on the CD when you buy PSE3.
