click on the camera drop-down list, then see if there's only 1 shadowlite cam. in my case, they get renumbered for some reason, hence I hafta guess which one is right. then click on one of the camera controls on the left, and the shadowcam parameters will appear on the right. depending on version, there will be a dial for "zoom" or "scale". decrease the number on the dial to zoom in. adjust x and y values to keep the object centred.
