Sunset Up Close and Personal

When the trees on the ridge 40 miles distant from my lens are in focus (more or less for the distance), the sun is scalloped and crushed The hundreds of miles of atmosphere the sun is filtering through, is distorting the suns edge. I get to watch those scallops move in real time when I set up shots like this. Big long lenses are necessary to do this kind of work.

When present, heat shimmer will create optical distortion that will diminish the quality of medium and long distance photos. trees at 40 miles is pretty hard to focus with moving air caused by heat islands in between my camera lens and the ridge. There is some distortion of those trees by the intervening atmosphere as well. Imaging anything over 20 miles I find you start running into distortions of various kinds. It’s not the lens, it’s the atmosphere.

What can you do about this distortion problem? Heat waves in the landscape are an image quality factor that you generally can’t spend money to put behind you. For example, a sharper lens and a better camera are not going to remediate the problem. . Selecting a different location, a different time of day and/or a different day completely or even a different season is often the best solution. A cloudy day with low temperature fluctuation may work for your image. Low angle moon and sun images are going to have differential heating between you and the moon/sun. Fact of physics and the environment.
