Reminded me of the old CCR song, "Lookin' Out My Back Door", except this was the front door. Caught the setting sun blazing through the front door as I walked down the hall and quickly grabbed the camera...A7R2 with Canon FD 35/2 SSC at f/2.8 and some help from IBIS:
Joshua and Manuel great images from your trip and I'm sure many more to come in the next few days after your return. You will need to let the rest of us know when your next travel workshop takes place.
Here's a couple more with the Sigma 120-300 2.8 Sport from Arches. First at 120 the second at 300.
Photo taken about 3 minutes after sunset June 26, 2015 from an overlook near the top of Cadillac Mountain overlooking islands, Mount Desert Island, Acadia NP, Maine. Image taken with my tripod mounted A7r and my Minolta CLE MC 40mm f2 M-Rokkor lens, ISO 200, lens set to probably f11 for 1/3 second. Color and exposure adjusted +0.36 stops. Processed in LR6.
