Camera applications can be great fun to play with and cost less than a cup of coffee. Here are my two favorites:

Hipstamatic: This application is based on Russian toy cameras and offers a choice of "lenses" and "film types" that conjure a range of looks for your images. The resulting photographs often take on a vintage feel. It is made only for iPhones ($1.99).

6X6: If you like the classic square images produced by 120 roll-film cameras such as Hasselblad or Rolleiflex, this is the app for you. The simple format produces beautiful square images. Also available for Android phones(99 cents).

A good roundup and reference source of iPhone photo apps can be found at the Next Web site. Check out its 30 favorite apps at www.startribune.com/a1020.
