Sweet bro!
You should be a guest speaker one of these days, for a meeting. Be nice to learn how to take better tanks shoots, bet even one here would come.
I have old school roots when it comes to photography, spent many a day in the ol' darkroom, for both color and black and white. But the thing that I can not shoot are tank pictures (close ups). I did get some new macro lens attachments that might help me with that, but have not had time to play with them much. Yes I vote next meeting you should be a guest speaker... hehe.
