Thanks Gordon.
So no advantage using Blue or Green then?

Graeme , I have had good results using a Variable ploarizing filter mounted to the camera . White light filters are often very bright and can take a camera's exposure control to the limits , the variable polarizer acts like an adjustable dimmer and will reduce the brightness .

That looks like a useful tool.
