Coastline 2

The sculpted outer wall of the front of the building, with backlit glass insets.

This area is minimally lit with a couple of small floodlights, and the colored lights behind the glass.

To the eye, it appears a uniform grey-brown concrete color.
Adding a camera flash, much more color becomes visible.

I have no idea if the artist intended this effect or not, but fully lit like this, the piece resembles a contour map or aerial view of coastal terrain.

Here, I'm shooting upward and across a section of it to maximize texture detail.
