OK, I got it, you have to set the Exposure to Manual, than it works. I just have to figure out how to change it on a T3i, as it does not have the Quick Access buttons on top. I would guess she can push some button on back and turn the dial and change the ISO, unless that is a feature not on that camera.
Thanks very much for the help, I'll have her turn off the Auto Exposure and set it on Manual and see what we can figure out.
