There are some amazing places to photograph in Louisville - and this might just be one of my favorites. Across the river - I realize it's not actually in Louisville - is the Falls of the Ohio State Park. I'm told there are some amazing geological features, as well as some really cool fossils and rock formations and some gorgeous sunsets.
I went out a few weeks ago with the new Tamron 24-70mm f2.8 Di VC USD G2 which is a bit of a mouthful but one of the sharpest, most amazing lenses I've ever used. I couldn't pick a favorite, so check these out.
