In 2005 I flew over Death Valley on my way from Needles, CA to Santa Cruz. I spent about an hour photographing the valley. One of my photos from that flight ended up being chosen as the main photograph at the kiosk at the dunes parking lot.
There is a lot of color in the valley floor. In some of these photographs I enhanced it with H&S and Color Range masks in PSCC. No color was added. Only what was there was enhanced.
