You might have seen small drops of water on grass, plants and trees shining like pearls in the early hours of morning. Often misinterpreted as rain left on the grass but not so much. For those of you that are learning this stuff…
Dew drops are formed due to condensation of water vapors. Air around us contains water vapors which we call moisture or humidity. Hot air contains more moisture versus cold air. At night when the relatively warm / humid air comes into contact with colder surfaces, water vapor present condenses on the cold surface in the form of droplets. These tiny drops of water are of course called dew drops.
The dew formation is enhanced when the sky is clear and reduced when it is cloudy. When the sky is clear and the trees and plants are cooler at nights, there is more evaporation of water and hence more dew formation. But when it is cloudy, trees and plants do not get cool in the night. This results in less dew formation. As the sun raises high in the sky, these dew drops evaporate into air directly.
It seems to me… We really don’t have an excess of dewey mornings here on the MT/WY border. Maybe we have more but I’m not seeing. This is after all a very dry environment. Frost is a similar phenomena but below 32 degrees.
The depth of the layer of smoke that gave me this apocalyptic image was early in the timeline that night. Keep this image in mind when I post an image of that sun setting into that mist. Here the sun is up high enough that the stepped gradient (natural not done in the digital darkroom). . Many stepped gradients from photographers are artifacts from improper digital darkroom technique. This is totally natural.
I don’t believe I have ever seen conditions worse than this. All sorts of backcountry outdoor activities are not occurring. Hard to cut wood when you can’t breath. Hard to do construction too. Some folks go about 70 percent effective under atmosphere such as this. Looks like fog, it’s choking, wood smelling smoke. 2020 is sure a mulligan year. Need to throw the ball out into the fairway and re-take the shot.
Of course, you couldn’t look into this to see it without a quality mirrorless camera. Just glancing at such a scene can do damage. I only look at scenes like this through my gear. Said camera moderates the intensity.
Disclaimer: I saw this scene on a live video screen within the view finder. I can adjust my settings real time accordingly. There is no direct light path to your eye in a mirrorless camera. DSLR cameras can blind you doing this kind of work so don’t. 🙂 Some cheaper small sensor cameras can’t take this either and doing it wrong is likely to burn your cameras sensor chip. With the full frame Sony A7 Series) I’ve taken thousands of directly into the sun images. No damage to your gear if you do it correctly. Getting your exposures too dark before you point at the sun is a good idea. Use highest f-stop and low ISO for this certainly. 1/3000th or so.
This is my last image of the Comet Neowise this time around. In 6800 or so years, I’ll get it next pass. It is traveling on a big loop around our sun. The bluish ion tail points straight away from the sun. The curved tail of debris off the nucleus is spewing off the curved race track the comet is on. This like so many chunks of gravel from a race cars wheels. Mr. Newton would be pleased to understand that his laws still seem to work. I estimate the light from this comet took about 6 minutes to get to my lens. It was far far away. At .7 Astronomic Unit’s distant from earth, it’s almost as far away as the sun itself when I took this. It is quickly getting further away and is only visible with good gear now. . 📷
Mostly I worked this comet with medium to wide lenses. I did however pull out a big gun for about 30 minutes. First of all let me say, This is a big aperture terrestrial lens (about 6 inches) and very fast at F4. Focal equivalent of 600mm. And I got about 6 seconds of exposure at ISO 3000. Any longer of an exposure and you’ll get long star streaks. I really should have tracked the stars and done minute long exposures at f200. Coulda Shoulda Woulda and all that. I keep pretty busy when I get a once in a lifetime opportunity with such clear dark skies. 👁
Tough to get set up as it was a little windy, big lenses have a high wind profile. A tiny wiggle ruins the image. I couldn’t even see the comet in the viewfinder. I was aiming blind literally. Set the camera in the general direction, take a photo, realign the camera and try again. This took 4 attempts to get it entirely in frame. If you look carefully you can see the tree line at about a mile distant from my camera. Close far perspective lololol.
