What you have will work fine as long as your camera has a wide enough range on the exposure setting. I go from -2 to +2 with 1 stop in between 5 exposures.

The mirrored ball I have is plastic but has a 12" diameter.  I've had it a while so it has a few scuffs on it.

 

Handle every stressful situation like a dog.

If you can't eat it or play with it,

just pee on it and walk away. :-)
