Every time I visit here I'm in awe of the place. After dinner at El Tovar last night we stepped outside and gazed down into the canyon... it was a magnificent experience! There just happened to be a double rainbow following a bit of rain. It was a bit of a challenge to capture the intense highlights of the setting sun on the cliffs and island peaks along with the deep shadows way down in the canyons, but the sensor in the GX7 captured the data to allow me to pull out all the details and compress the range - great dynamic range capability with this camera. GX7 with 9-18 lens at 9mm and f/4.5.
