I did a little experimenting tonight. I found that as I focused in/out of the lights, the arrows would vary in size, quantity, clarity, and even direction. All of these were shot at 70mm, f/2.8, ISO100. Shutter speeds varied.

It's been a LONG time since I've studied optics. But don't upright images mean they're virtual? And inverted images are real, right? Ah, I need to review...lol.

it's either that way or the other way around... it's been too long since physics class :( I did save that book. I could go look it up... but I'm too lazy!
