I've been coming back to this spot in Marquette every other trip up... I really want to get a photo I like that involves this little concrete painted up tunnel, but I've yet to crack that nut. I know there's some kind of framing or perspective that I will love, but so far it's eluded me.
It's a neat little spot - there's a small waterfall right down behind this, and the long water pipe above looks ancient and sometimes leaks (in winter you get lots of ice formations as a result.)
I think the problem with the framing is that there's basically just about 15 feet of a three-way tunnel of concrete sitting there, but the outside of it isn't super photogenic. I'm thinking that it would have to be a "model" shot, with a person involved... where I could maybe do a silhouette at the opening... maybe a night-time shoot would work, with some creative lighting to highlight the paint...
