Today was an *extremely* cold day here in Michigan (high of 8* Fehrenheit), but it was a very bright sunny day too. Seeing that such sun is infrequent in Michigan in the winter, I decided to do some spotting.
I started at the McNamara deck (Level 9) because the planes were landing on the 4s. After 45 minutes of shooting, I finally gave in to the cold and got back in the car. I had my laptop with me, so I uploaded all the shots and took a look.
EVERY shot had noticeable heat haze!
I couldn't believe it, since I hadn't noticed it with my naked eye, or in the camera's review screen. Obviously, a 400mm lens will pick up things that the human eye didn't notice, but that really sucked.
By this time, the landing pattern reversed, so I went to a different place to spot. No heat haze along Smith and Wick roads, for those of you familiar with the airport.
I think the heat was coming from the hot cars in the lower levels of the parking deck blasting their heaters. If I'm right, then this should help other DTW spotters: beware of super-cold days. I think the temperature differential at the McNamara deck is too much to overcome.
