This is such a fun topic, and I'm sure we'll see some beautiful representations of "Light"
This is a medieval wrought iron candle sconce erected in The Cloisters (The Met) Museum in NYC.
It was hard to frame because it was so high up and surrounded by other objects/artifacts but its shadow was *so* beautiful.
It was a grey, overcast day but I had dark amber Rx sunglasses at the time and I was walking around going, "O my god, guys! They sky is SO BEAUTIFUL!" and everyone looked up at their grey, dreary day and it just looked...drab. However, MY view was AMAZING. This was me trying to capture both the drab reality and the high-contrast bursting orange light/shadow I was enjoying.
