Nice work guys. Totally love Jeff's dancers and liminality...I had to look up that word!
I did know about Mercury though...there's an old mine down near Terlingua in Texas. Lot's of interesting history...
Back to photos...mine is a test shot from an old Ricoh KR-10 super that I use for astrophotography. Turns out it doesn't focus at infinity, but in front of it...so it's been a stinker as I don't want to toss it, so am trying to figure out a solution short of just buying a spare body to use.
Anyway, just some dead grass...shot with the Rikenon F/2, which I like a lot as a cheapy lens to knock about with.
Oh and Arista 100, dunked in caffenol... my usual potion
