Observe this photo: It's uncropped to give perspective. That city wayyyyy in the background is Minneapolis, about 18 miles away. When the weather is right, the valley in front of it will get foggy, and as the sun rises the fog explodes with purple, pink, orange and red - it makes the city look very surreal or, depending on how much fog, like it's floating above everything. So, if you were me, how would take this shot? I'm thinking of using the 70-200 f/2.8 @ 200mm, on a tripod early in the morning as the sun rises, but I'm not totally sure. That's North by the way, so the sun will be rising on the right. I've come across the perfect scene for this a few times, but I just haven't had a tripod with me, or else I'd pull over and arrange it. But I want to see if anyone else has any ideas. I may HDR this one.
