Reader Alison Carlino asks, via Twitter:
"How could I light posed formals in front of tank w/no umbrella reflection showing?"
Welp, there's good news and bad news.
The bad news is there is no way to effectively stop those reflections from happening. I mean, it's a CYLINDER for Pete's sake, right?
Fortunately, there is also good news. And it'll probably result in a forehead-smack moment for you.
