Big Stopper - 5 and a half minute exposure (327 seconds, to be exact). I think it's my only photo with the filter, actually. I've taken it out a couple of times to test, but didn't have appropriate subjects. I bought the filter in 2013, too. Anyway... I trespassed onto someone's beach to get the shot. Didn't really like doing that, but I was where I was and wanted to photograph this little bridge/pier. I spent about 15 minutes crouched really low and trying to set up - hiding in the family's back yard (they were getting ready for dinner, it seemed like). If I could do it over, I would have gotten a slightly higher or lower perspective so that the horizon didn't exactly match up with the handrailing on the bridge. Go figure how I managed to line those up exactly... sort of ruins the shot, but I like the image because it was the first time I had to hide from being found on someone's property.
