| I never thought of that, but yes that will really work. That's a damn good tip.
Any real disadvantages of doing this compared to using a normal ND filter, other than potential vignetting at wide angles? | |

Offhand, I can't think of any. Using two as I mentioned, makes it a variable filter. Make sure though that you get the best quality that you can afford. If you buy a chunk of expensive glass, then make sure that you use a good quality filter on the front of it.
