When it comes to spot lights,
once you give the light operators your instructions,
it is out of your control. To prevent any
troubles, make your directions before hand,
clear, and as simple as possible. Sometimes
mistakes happen, a personal friend of mine
used invisible thread in an act, unfortunately
the operators used to much lighting and
the thread was reveled. In his case he went
on with the trick. Fortunately he did not
use the thread much, but he did not handle
the situation perfectly. If you have lighting
problems, fix them in rehearsal, if the
problem is unavoidable, do another trick
or modify the problem trick.
