90 yo Dad did just fine with Death Valley. He wouldn't get up early, but at least we caught a few sunsets. Didn't do The Racetrack, but Titus Canyon was a rough road adventure; too bad it was mid-day. This is just a travel pic, but was experimenting with incremental focussing points down through the frame. Thought this was the best compromise viz sharpness of the salt/mud blocks and bkg mountains. Did something very interesting to the clouds; honest, I didn't touch 'em. FWIW, 1/250, f/16, ISO 400 at 28 mm.
