One of the options for my photography course is "Reflections". I considered doing it, but instead I'll be focusing closely on rocks. It occurred to me that there are two meanings to "Reflect":
"to cast back light, heat, etc"
"to think, ponder, or meditate"
It then occurred to me that these two things are connected. Many things we think, ponder or meditate on are about the world and how we fit into it, how we reflect our environment and how we want it to reflect our way of thinking. We reflect, think, about things we don't understand and our thinking casts light, reflects, upon them. And vice versa.
Cheers, Tom.
