Here's a closeup view the newer, western section of the Baltimore Convention Center. The repeated triangular truss design elements make it a very strong-looking building. Another exception to Baltimore's unfortunate dearth of fine examples of modern and post-modern architecture.
Taken with Ben's Canon A630 digicam. This is from this morning's walk to work from the Light Rail. My stop is right across the street from this part of the Convention Center. It was a dull morning, so I bumped up the saturation, which also bumped up the noise in the sky. So even though this is an 8MP sensor and the exposure used ISO 80, noise can still be a problem in these little cameras.
I pretty much cropped in-camera for this one, but then I cropped just a little more to get the little blue (sky) triangle as negative space at upper left. See all the positive and negative space triangles in this image? Do you think it worked here?
