DVX's NDs = Stops?

I know I've seen it here before, but couldn't find it...

The DVX's ND 1/8 is how many stop loss, 3? And the ND 1/64 is 6?

Thanks
 
The NDs on the DVX are pretty extreme. Having a nice ND .3 is great if you are just looking for a little exposure help without using the internal NDs.

of course it is, but you cant always afford a matte box. and taping a nd .3 or .6 or .9 to the lens isn't the best idea, IMO, gel or glass.
 
I dunno, I'm actually finding that the .9 and the 1.8 are great NDs to have in camera when you're shooting outdoors.
 
You need the powerful ND's in-camera to get you close on bright days, then the iris takes you the rest of the way.

For those interested in controlling the iris for DOF purposes, carry a .3 and .6 around. With those and internal ND's, you can do one-stop increments from 1 stop to 9 stops! That's what's in my kit, B&W screw-in ND filters .3 and .6.
 
I'm confused. All of these ways to explain the level of filtration. The camera calls them 1/8 and 1/64, but when I search for add-on filters they talk about them in terms of .3, .6 etc. OR they are referred to as ND2, ND4, etc.

How do I decipher this? Can someone help?
 
Each .3 = 1 stop. ND filters are calibrated in 1/3-stop increments, so an ND .1 would cut the light by 1/3.

Each stop = 1/2 the amount of light coming in. So ND .3 = 1 stop, or half as much light.

The DVX lists the numbers as to how much light it lets through. In 1/8 position, only 1/8 as much light is getting in. Which is equivalent to three stops, or an ND .9

In 1/64, it's six stops of ND, or ND 1.8. It allows 1/64 of the total amount of light to pass through.

1 stop = 1/2
2 stops = 1/4
3 stops = 1/8
4 stops = 1/16
5 stops = 1/32
6 stops = 1/64
