Thanks for the advice. Shooting through glass is obviously not optimal, but, on occasion it can yield good results. I see it as a challenge, and I am also interested in airport architecture, interiors, bulk flow of passengers through terminals, between sterile and non-sterile areas, ground support equipment, and the whole works. Shooting from behind glass is the only option for much of this unfortunately (except at HNL!)
Here's a real mammoth dug up from Siberian ice and on display (behind glass) at the St. Petersburg (Russia) State University Zoological Museum. I took this photo last July.
