Hi Brian,
This was just the ND4 mate. I am still experimenting with them all. Any change in light Or angles makes for different results. It's a learning curve for me mate
Yeah, it's all about finding what works best. I have experience with circular polarizers for video cameras and just picked up a set of the freewheel hybrid ND/Polarizers for the X-Star. Haven't a chance to use them yet but thinking I should have just gone with plain NDs to start. We'll see!
