I was wondering if there is a certain way that I have to save my CS5 photoshop file so that it can open up in CS4. I use CS5 at home and at school we use CS4 and I know in Illustrator you have to do that but you just save down and in photoshop I don't see the option to save down.

In Photoshop CS5, go to Preferences > File Handling > Maximize PSD and PSB file compatibility, and choose Always or Ask. Then save your file.
