I love how the images are in grayscale!

Represents the fact that all these photos were taken during the graveyard hours far better than if they were in color.

Also, it's likely pretty dark everywhere the photos were taken so the available light for photography is not great. So, shooting with high ISO/gain settings is going to be pretty noisy, which is less noticeable when in black and white.

You'd be surprised what a modern full-frame sensor picks up these days. They're not shooting with a D2H in 2004.
