How to see what picture we are taking

The D60 works as SLRs have worked for half a century, providing a viewfinder through which you frame and compose your picture. The screen is for menus, settings, and reviewing pictures you've already taken. The LiveView feature which lets you use it as a point&shoot camera was introduced with the D300, introduced a year after the D60.

Sorry if that wasn't the answer you wanted to see, but that's the way this camera works.
