After discovering the "need" for a longer lens, I bought an 80 - 200mm one and after some test shots, returned to Magnusson Park to photograph Mt. Rainier at sunset. None of the mountain photos have been touched up. The non-mountain photos have been adjusted - specifically the dark areas have been brightened.
Notice the orange sun light on the snow covered top is rising through the sequence of photos.
Looking north, with aircraft vapour trails being at a high enough altitude to still be in sunshine, while the ground itself is no longer illuminated.
