A few weeks back, I purchased a Cokin Z filter holder and a pair of Lee filters. I'm loving them so far. I used the 2 stop hard grad for this shot to darken the sky and even out my exposure. It worked out very well. I think it will change the way I shoot landscapes (thanks to Todd H).
Other than that, I applied some Nik Color filters and did the LAB color trick to make the colors really pop.
I already posted a shot of a much different Pittsburgh dock about a month ago, so this is the second shot, making this a pair of docks (cue Jungle Cruise laughter).
