Software SolutionsCamera Tool changing computer resolution

The resolution settings are quite different now on the Mac.  Currently it is set to “default for display”.  When you hover over the default it says “Looks like 1440 x 900”.  I’ve tried changing it to any of the available resolutions, but it still magnifies when I go into camera.  Attached you will see what my screen looks like at first and then what it looks like when I click the camera tool and the desktop camera tool does the same.
