I think the spook factor in this picture comes mainly from the lack of light and color. The colors are dull and monotonous, and light only exists in certain spaces. It gets blacker deeper down the staircase. The black shape on the left wall looks like some sort of shadow, but when examined more closely, you can see it’s a window to a dark place. There is an air of mystery about the entire photo. I can’t tell what’s at the bottom of this staircase or beyond these rusty walls. A lot of what’s here is hard to identify due to the lack of light.
