Has anyone used a 10 stop ND filter? Im interested in getting one, but Im concerned that its so dark you can't compose your image w/ the filter on the lens, similar to a IR filter.
Can someone tell me if it is in fact that dark?
Thanks. |

You won't have any problems using it in bright sunlight.
I haven't personally used it under any other conditions.

A 10-stop is ND filter is certainly very dark.
I use the Cokin Filter System and with it, I can achieve 10-stop filtering with a 2-stop and an 8-stop combined. The beauty of Cokin filters is that you can not only combine them, but (if needed) you can compose your image and simply slide the filter(s) down in the slot(s) before you shoot.
If you want graduated ND filtration, another advantage of using Cokin is that you are not limited to having the dividing area directly in the middle of the filter. In other words, if your composition has the sky in only the top third of the image, you can slide the filter up so that the darker portion is covering the sky only. This is a huge advantage over traditional round, screw-on filters.
On a side note, I read about a 14-stop ND filter made out of welding glass. Check it out.

This is a cool ND filter that Singh-ray provides:

...Of course the cheapest of these is $340
But still cool. Personally I see myself trying the welding glass trick before the 340 singh-ray

| It is very dark, and quite hard to compose using the viewfinder. I always use the live view (set to exposure simulation I think) and maybe pump the ISO just for composition. Then switch off live view (so it will focus on the 40d), drop the ISO back down and take the shot. I also sometimes pump the ISO to max and take a quick shot to make sure the comp is what I want before taking the long exposure. The other option is to compose before putting the filter on but that is a pain to take it on and off. Remember to block the viewfinder with the think on the strap otherwise light will enter from the back of the camera and ruin the shot! (as I found a couple of weeks ago!) |

It is indeed very dark. You can't compose with the filter on. You can get a bit lucky if the day is very bright and some important lines stand out, enough for you to orient yourself. And perhaps if you have those DSLRs which have a brighter viewfinder. I shoot with the 20D so maybe folks with a more recent can see a bit more detail. But the trick is, you also have to pre-focus. I can tell you it's very annoying to use on the Canon kit lens or any other lens with a small focus ring at the very front of the lens barrel. You have to hold the focus ring in place while you screw on the filter.
Overall it's a very fun filter to have. Here's the most recent shot I took using it
