Yellow Alpenglow Borderland Vista
Alpenglow occurs both before and after sunset. You see different colors with time as the sun light moves has to plow through progressively longer paths through the atmosphere. As the horizon draws closer to the sun, the colors that survive the trip are longer wavelengths like red and orange. Rich crimson is the result of only the longest wavelengths making it through that smoke, dust, moisture laden longest path where the light is actually bent around the globe a bit. Yellow skies like this are late results of a clear sky sunrise. Yellow is the last gasp of the twilight deeper colors. Blue Sky isn’t far away. (This is a VERY small area of the sky and the close ridge is 5 miles out)
Alpenglow as this exists because suspended atmospheric ice acts as a projection screen dominating the skies in the winter. What you see here is the result of illuminated/ lit up suspended small ice crystals shining yellow. That is the dominate color for this length of travel through the atmosphere. Just a few minutes before, this was red as these stage shows constantly change the set of the play.
Don’t forget: When the moon or the sun is ON the horizon, it is in reality below the actual line of sight. Hiding behind the earth. It’s image curves around the globe a little due to the atmospheric lensing. Only orange/red light makes it through that gauntlet giving us twilight colors.
Musings on working ridges with cameras. :
I am always looking for Layers of ridges. A “Landscape Ladder” so to speak. Working the high ridge country here on the Montana / Wyoming border is wonderful for finding such “ladders”. Parallel Ridges aligned at right angles to the sunrise and sunset creates unlimited opportunity way to work shadow lines photographically. You can usually find dozens of worthy sunsets and sunrises captures on the ridges following/moving along that shadow line. Many interesting foreground objects magically appear that way. Those are useful in the close part of the close/far perspective (the goal) . Start an hour before the event is my suggestion.
This method of working the landscape works very well for moon perspectives I find. Moving along that shadow line, on an opposite ridge, I’m able to maneuver down topography for a sunrise and up for a sunset. One can follow the sun/moon up/down over the “event” by changing my position. Ridges let me work the moon (for example) for an hour instead of 5 minutes that I would have on flat ground. It helps to be very agile getting about too. Cover more ground, get more captures.
