Went down to the woods late this afternoon to test out my new 0.9 neutral density filter, though it was actually getting too dark by then to be doing this. I took a few long exposures in the stream using ISO 100, f22, 30 second exposure and of course a tripod. The results were under exposed by a couple of stops, but I was able to correct the exposure of the RAW image later. Not exactly the Niagra Falls but I was quite pleased with the result anyway. Am looking forward to getting creative with this new addition to my camera bag.
