My latest addition to my photo kit is a set of Singh-Ray “Mor-Slo” solid ND filters. I got these filters in both the 10 and 5-stop varieties in 4×4″ square glass.I chose the Singh-Ray filters in this style for a few reasons. While all solid ND filters tend to have a slight color cast, the Mor-Slo filters deliver a pleasing warm tone that is simple to correct in RAW. My other 10-stop ND is a Lee “Big-Stopper,” and it produces images that are incredibly blue– not impossible to correct, but not as pleasing, either. Secondly, the 10-stop Mor-Slo has a unique foam gasket design that helps prevent light leaks. I chose the rectangular glass option because it allows me to use the filters in a standard Lee holder (Foundation Kit) and easily stack filters (including ND-grads) without vignetting. In addition, it’s very easy to remove/attach the filter holder from your lens in the field; something that is somewhat more cumbersome when you use screw-in filters.
Armed with 15-stops of ND goodness, I captured a couple of shots that I’m pretty happy with! If you’re interested in learning more about long exposures, check out my tutorial video.
