Does anyone on here use a Lee 4 stop ND filter? I'm thinking about getting one for slow shutter speeds in fairly bright conditions. I'd love to see any examples if anyone has one?

Hi Richard. I have a Lee 0.9 ND and also the majestic B+W 10 stop ND.
It was this shot by Gary that prompted me to get the 10 stop one: http://www.mysteryme.com/index.php?showimage=300. Some other examples:

My method is to tend to stop down to f/16 (or f/8 is quite successful), use ISO50 or 100 and engage mirror lock-up. After focusing, I click to lock the mirror up, whack on the filter and open the shutter with a shutter release cable. Alternatively use auto-focus and then switch to manual focus before putting on the filter. You can't see anything through the lens with it on.
I use a Canon timed remote which enables me to dial in how many seconds I want the shutter to open. It's best to experiment but after a while, you get a feel for how long the shutter needs to be open, and always use the histogram as a guide. If you use f/16 and the 10 stop around dusk, be prepared for exposures of 400 seconds.
I find that the use of the filter has to bring something extra to the image, e.g. I took a shot a waterfall with and without the 10 stop - both images (at 4 and 270 seconds) looked the same.
Hope this helps.
Hi,
Am I correct in thinking that the B+W is a screw on filter? I have the Lee slot in filters and would like to know how you can combine the two?
Can you get adaptors so I just need to buy the largest B+W 10 stop and buy rings to allow me to use on smaller diameter lenses.
Thanks,
john
