Long exposures

I got a new camera, a Nikon D50. I spent several hours yesterday figuring it out.

The top exposure was an image of my waiting for the bottom exposure, namely, got the heater to turn on again and produce the steam. So, for that top picture, I just opened the shutter, and walked around for what could've been 4 to 8 minutes, and then finally closed it. The lower shot was obviously much shorter, probably around a minute.

I find this building so bland, I never would've thought I'd be taking a picture of it, but the shadow was so enticing.
