Last Minute: Blue Lights in Boston

In honor of the anniversary of 9/11, a number of building in Boston and Cambridge will be lit up in blue.
We'll cross the Longfellow bridge and see what views we can get from both sides.
Bring wide angle, or medium telephoto lenses. A fisheye might be fun as well. Since we'll be getting there during twilight, bring ND filters to help with long exposures.
It goes without saying that a tripod is a must.
Keep in mind that our camera sensors are more sensitive the blue light than red or green. Enable your RGB histogram and watch the highlights.
Wear comfortable walking shoes, we may decide to walk to some of the buildings to shoot up close.

Good for all levels of skill: Well lit urban area.
Please check in with the organizers before going off to shoot, and as always, no guests please.
