that should have been a multiplication.

| Apr 2, 2011 at 1:35 | comment | added | Joanne C | Excellent! To quote Mr. Burns. | |
| Apr 2, 2011 at 1:35 | comment | added | Itai | You forgot to explain the law of stackability failure ;) Two 3-stop ND filters = 6-stops, but three 3-stop filters equals 9-stops in the center and 10-stops along the edges due to vignetting. | |

| Apr 2, 2011 at 0:28 | comment | added | Joanne C | +1 but you could have summed up as 6! | |
