I recently saw online that they have white balance lens caps you can put over the lens and set the white balance. Are these accurate? And how can it see the white if there is no light getting into the lens?
 
it must be translucent

I dont get these things because if your scene is a full frame of a snooker table then how can it percieve the balance between a green subject and a green cast

I spose if you go near / pointing at the light source it is a good solution - possibly not easy on sticks

expodisc are the people who are serious about his technology
