New night-time images

Got a new Canon 5D Mk2 21mp DSLR camera months back, and have been using it mainly for shooting HD video. However, it is a superb still camera as well (one of the reasons I bought it), so after being woken up after three hours of sleep and not being able to get back to sleep, I grabbed the camera and my new tripod and went looking for vistas of interest. I used to do this sort of thing back in my film days, doing long exposure shots of buildings and architecture at night on Kodachrome 64 slide film. The trick is being able to visualize ahead of time how the lighting will balance out and how the colors will shift. For Kodachrome 64, the typical exposure was between two and four minutes at f/11, allowing for reciprocal failure.

With digital, with an ISO of 1600, exposure averaged around eight seconds at f/11, plus you have the luxury of knowing immediately what the image looks like. Here's five scaled images from the shoot. Two are of a tollway overpass that has always fascinated me with its soaring structures, one is of an overpass pylon being cast, one is of a commuter rail station under construction, and one is of a brick street curb in a town square.

Nice shots dude. Can it do bracketing exposures?

The 5D Mk2 can support ISOs that high without unaceptable amounts of noise?

The 5D has a honking HUGE sensor (physically as well as pixel count). It's actually LARGER than a standard 35mm film frame. That means the imaging cells aren't crowded together as closely as a smaller physical sensor, so there's less noise and cross-talk. I've pushed it up to 6400 with visual results similar to shooting on Ektachrome 400 film -- some noticeable "grain" when enlarged past 8x10, but acceptable.

What you see here is considerably reduced from the original 21mp jpegs, but other than some digital "burning" and "dodging," what's on the screen is what came out of the camera.

It's a built-in function. I've never used it, but it's there. I bought the camera because with the larger sensor, it has the 35mm depth of field and "look" in HD video without having to use a DOF adapter.

You should experiment with bracketing. You can achieve some cool results if you use them to create an HDR image.
