Believe me, as someone who has magic-wanded out more backgrounds that
I care to admit... it works really well SOME of the time. Other times
you a messing around with the magic wand sensitivity setting to keep
it from grabbing portions of your object.

Bruce is correct. Your images are seriously underexposed. The light
table should be white. It's the same principle as shooting something
on a snow bank. The meter will make the snowbank 18% grey and
underexpose the subject. That's what you've got here. You'll save a
lot of work in post if you expose correctly. Either get off automatic
to manual or use exposure compensation.

Also, if you have photoshop you may find that working with levels or
curves (to define your "white") will save you a lot of time with the
magic wand. Trust me, you don't want to rely on the magic wand.
