WB and ND filter

Hello, what is the difference between setting a/b/preset for white balance on DVX100B? Is one setting better then the other?
Also, what is the relationship between WB and ND filter?

Thanks,

The A/B allows you to set 2 different white balance settings manually. For example you could white balance A to the lights in a room, then white balance B to the lights from an on-camera light. So you could change lighting and all you'd have to do is flip the switch to accomodate. Same with the presets...but they're for indoor (3200) and outdoor (5600). I have found that using the ND filter doesn't affect my white balance, as it just limts the amount of light entering the lens.
 
Thanks for the clearification. Everybody recommends not using the ND filter as it tends to create too much noise in the film.

Cheers,
 
Yes, A and B are just two different slots for saving your white balances.

A cool thing with the DVX is that it actually fades between the WB-settings when changing. This is very useful for instance if you are using a moving camera following a person from a place outdoor to indoor (or the other way). With a little practice you will know exactly when to change the switch and the dvx will make a nice "WB-fade" to the new color temperature making the change almost invisible. Pretty neat stuff really, that many cameras won't do! =)

Regardning ND-filters and WB. No, there's no real relation there. The ND-filters do not color the light. They are made to only reduce it.

To make it really simple: You can see them as a pair of sunglasses for your camera. When the light gets bright instead of squinting your eyes (having the IRIS almost closed), you put on your sunglasses and can have your eyes (IRIS) normally open where they work the best.

...and if you then add a polariser then all of a sudden your dvx got a nice pair of polarized sunglasses on it! =)
