if they do, they're silly. mirrors absorb more light than they reflect.
yep, you're right. mirrors are a bad idea. they only reflect light back to one point. and they abosorb alot of it too.
They can also create hotspots.... I use white poster board.
light-wise, a mirror is like a 'black hole', no good ... go with flat-white surfaces :thumbsup:
