Sunset On the BigHorn Mountains

Sunset Across the 130 mile Distant BigHorn Mountains is one of quite a few BigHorn Range captures over most of last week. Amazing stuff 😲📸

Watching this alignment start up with the sun WAY left of the range less than a half hour before this. The sun will always move from left to right as well as downward. Of course it’s the horizon rising but you already know that. (The sun isn’t moving here, the earth is spinning) . The earth is tilted on it’s axis

Science Factoid:

That tilt is relative to the solar systems flat plane called the ecliptic. All the planets are circling the sun on that plane. The earths north/south axis Currently, the Earth’s axis is tilted 23.5 degrees from the plane of its path/orbit around the sun. But this tilt changes/wobbles like a top. During the long wobble cycle that averages around 40,000 years. (Based on good scientific work eh? 👁

The tilt of the axis varies between 22.1 and 24.5 degrees. Because this tilt changes, the earth is exposed to differing amounts of energy from the furnace over that interval. Paleoclimatology is something I have dabbled in. I will tell you the sun is the driver of our climate so one would assume that global changes occur as the way you face the sun. Yup, the climate has been changing since it all started as a pool of molten rock accumulated in a gravity well lol.

SO back to this photo:

This time of year, sun sets dramatically from left to right as the horizon rises here. But it rises from left to right at sunrise. (The phrase to google here is Ecliptic solar system). So tracking this and watching it change by the minute was very impressive.

Photographic Musing:

Bright bright bright stuff. Shutting the camera down to light ALMOST taken with the len cap on (it’s that bright lolol) You only have 3 main things to set on your camera by working it on manual mode.

They are: “ISO” (Camera Sensitivity), f-stop (aperture or pupil size of the lens) and Shutter Speed in parts of a second (s). Figure out what is important to you (deep focus or freezing motion?). You set f-stop high for deep focal field . F-stop low for shallow depth of focus field. F-stop takes away light so high f-stop (small hole in the lens) is good for high light situations. Priority 1 taken care of.

Your next priority (2) is ISO (camera sensitivity). Low ISO is ALWAYS best because High ISO give you too much light AND a grainy appearance in the image. So LOW camera sensitivity (or slow ISO 100). High ISO is best for LOW LIGHT situation. Really HIGH ISO over 2000 is for the dark if you need it only. I consider ISO evil to go high with.

Last thing on the list is shutter speed which is your variable to adjust the total exposure. You adjust until you get the result you desire. On an older DSLR reflex type camera, you look at the image on the LCD on the back of the camera body AFTER you take the photo. With a Mirrorless Removable Lens Camera though, you get what you see on the screen INSIDE the camera, WHILE you are moving the dials the image reflects the changes you make. What you see is what you get. Instant feedback, MUCH easier for you to learn on. So if you made it this far in my text, and your looking at cameras, pick a mirrorless model, preferably a full frame/large sensor camera. Full Frame cameras have higher dynamic range than smaller sensor cameras. 📸


Don’t USE a standard DSLR camera to take sun photos and YOUR camera may not be rated to take this heat. Large sensor cameras spread out that light and don’t melt like some smaller sensor cameras would here. More important, don’t blind yourself in a DSLR even trying this. Seriously!👁
