Some of the pre-sunrise drives out into the backcountry are silly amazing sometimes. It takes me a minute to get set up for this kind of location. I usually have photographed the sight a different day . This fully involved twilight sky was colorful icing on the cake from that morning’s long timeline.
The term “Twilight” means 3 different things: Civil Twilight begins about 28 minutes before sunrise or ends 28 minutes after sunset. It is that period from when the sun is about 6 degrees below the horizon. On clear days you can do normal outside activities that require light. That solar elevation angle below the horizon defines each twilight phase. CIvil Twilight is by far the brightest of the three twilights.
Nautical Twilight starts when the sun is 12 degrees below the horizon technically. Both the Horizon AND brighter stars/planets are visible in this twilight. It is the “middle” of the three twilights. At the beginning of Nautical twilight, it’s about one hour to sunrise.
Rule of thumb which varies with your position on the globe, is 28 minutes each twilight. In Astronomical Twilight, If you live in the city, you have probably never noticed astronomic twilight. The are NO shimmers of daylight at the beginning of Astronomic Twilight a full hour and a half before sunrise. .
Away from the lights of population centers, we see Astronomic Twilight regularly where there is just a slight greying of the black totally dark sky mid night. It gets as dark here on our ranch in remote northeastern Wyoming as the North Atlantic Ocean according to NASA.
Perspective: Pine Noodles Bough is a capture initiated by the -2 degree morning, the icy air and the lighting. The later of which was JUST coming over the ridge but about 15 minutes after sunrise.
Topographically, I’m working just over the lip of that higher ridge. Opportunities like this after photographing that sun coming up over a ridge 20 miles out are important parts of the timeline. I move quickly to transition to working a closer ridge several hundred yards out as the sun climbs. A sunrise is a period of moving from place to place to take advantage of the terrain. It is very important to know WHERE to and WHEN to move to the next shot. Extending your time working the “Golden Hour” is the result. You only have so much time to “Work the Light”.
I work “Parallel” ridges because I’m very mobile to look for interesting leading lines and angles. Here I saw this long pine bough covered in ice from freezing fog the night before. (the night I’m typing this the same weather is occurring and I’ll be up on the ridges for sure ). There was an 1/8th inch of ice on everything that was exposed to the wind. So a vibrant landscape with an interesting weather event… (a hero as every photo needs a hero). But working that shadow line is the game.
The glare from the sun is quite a hard thing to deal with. I am literally looking into the sun with this camera with a white ground reflecting light plus the ice. You’ve GOT to turn your camera to HIGH F-stop, LOW ISO and your shutter speed is used to balance the equation. If you don’t want a sun star, go f-11 mid range. You adjust either with a neutral density filter in front of your lens (I hate them), or higher shutter speeds. Many consumer cameras don’t have 1/8000th shutter like the higher end models do to compensate . So faster shutter speed to reduce light into the camera may not be as much of an option depending on your equipment.
