I finally got to take a little vacation and decided to do some shooting along the way. Along with my truckload of gear I brought along a new toy: the B+W ND 3.0 MRC filter. I picked up one from B&H last week. It is a neutral density filter, but just not any neutral density filter. It decreases the light coming through the lens of the camera by a whopping 10 stops (even more if stacked with other filters like polarizers). Why on earth would you want to reduce light transmission 10 stops you might ask?? From what I understand, this filter was made for astronomical sun studies, welding applications, anything that would involve photographing insanely bright things. Along the way, photographers discovered this filter had another use. It allows you do long exposure shots in broad daylight! Imagine the kinds of things you can do with 30 second exposures in broad daylight! Unfortunately this specialty filter does not come without any caveats. There are two issues with such a dense filter. First, seeing through the lens is damn near impossible with the filter attached. Second, autofocus is also rather difficult. You also have to use a tripod for the kind of work I'm interested in. What you end up having to do is composing your scene and focusing with the filter detached, putting on the filter, and then hitting the shutter. Your camera may also have difficulty metering so there's going to be some trial and error getting the correct exposure. It's definitely not a filter for the lazy but I've had a lot of fun with it so far. Here are some examples from flickr that people have shot and below you can see some I took today. I'm hoping to get more shots with the filter while I'm down on the coast (it's great for moving water) so stay tuned!
