Some of the Post-sunrise evening drives to return home I take to get set up in beautiful locations I have photographed earlier. . This ColorCast evening was colorful icing on the surface of the ice and snow reflecting it’s qualities to my lens. This is a twilight sky after sunrise.
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.
Taken VERY early in Civil Twilight, this is a very deep focus close/far perspective. . I was watching this wonderful alpenglow/wispy cloud gradient already on a remote high ridge. I noticed the much wider view in the foreground camera than the actual background in the camera I was holding.
Getting around in the backcountry during twilight:
Up here in the Wyoming/Montana borderlands if you want a big view, you have to gain altitude to do so. The ridge tops are 4000 feet in elevation. Everything else is lower in this area. The lower streams are 3600 feet. We are actually very low topographically for Wyoming (but I digress). How easy it is to gain altitude depends on where you are going of course but winter makes this much more relevant a discussion. Climbing up backcountry two track trails is usually hazardous at best lolol. This complicated with snow blowing around. Being able to read snow drifts is a good skill in this country.
Where most people get in snow trouble is when they get off the crest of the ridge. The snow is always less deep on the crest as it blows off to the edges. Up here Yucca and Sage Brush will trap snow. Taking a path through the vegetation isn’t the best of ideas. Best have some backup with you if you try.. I’ve got a shovel and a radio . Since I have the most snow capable vehicle on the ranch, I’d rather not stick my rig as getting something else to it would involve a skidsteer with chains and a bucket. Building roads is no fun lol.
Photographing Moor Rising: Lone Tree is a combination of finding the right position in x/y space, timing and distance is z, and that position moves with the speed of the moon which makes using Tripods very difficult. Maybe a monopod….This was handheld. Distance is your friend here from that Lone tree. I’m about 600 yards out from it for this shot. This is a full sized image not a crop. Doing this kind of photography has found me on my butt more times than any other. The moon is constantly moving, I’m usually on some parallel ridge walking forwards (as the moon is rising and to the left a bit while looking through a 2 foot long lens (tube) and not at my feet with sage brush around on uneven ground.
Capturing this kind of image is a “sub-hobby” of mine within the general photography that I do. I find it a seriously fun challenge to get terrestrial objects in the same focal plane as the moon or the sun in twilight or darker conditions. It’s a good skill to hone for when the right situation presents itself.. Like this 📸
You have to get working that camera on Manual if you want to do this kind of work lol. Cell phone cameras need not apply and won’t do this without an external lens of some rigged hook up….lolol Lots of fstop, then all you have to do is adjust the other two parameters left, ISO (camera sensitiviey) and Shutter speed. I’ve covered that many times elsewhere so I won’t do it again here 📸 Suffice to say, distance is your friend here and lots of lens to do this.
