Sizing the Photograph

Being able to size the capture rectangle is not a substitute for composing the captured video properly.  In the above picture the desired area is about as large as it can be but is too far to the right.  The nearly full size rectangle can be dragged from its initial central position to bound the desired area and the Save button can be pressed.  But in the following picture the desired area is too small and the box must be shrunk significantly to capture the desired area.  This will result in a low quality picture being saved because most of the information in the picture is discarded.  This situation should be avoided wherever possible, to maximize the quality of the saved image.
