Using Zoom with the iPad Camera

Finding the zoom control for the iPad's camera can be tricky at first.  When in camera mode, you must tap on the screen (anywhere), a slider bar with a +/- along the bottom of the screen will appear.  You can now slide your finger left and right along this bar to control zoom.  Just a tip, this feature can be finicky, sometimes I have to tap a few times before the zoom slidebar appears.   Below is a screen shot of my flowers that I took to show what the slider bar looks like.
