Welcome to day 283 of 365 photos…as I looked skyward at about 8:30 this morning, the sky was covered with contrails. The white trails on the blue sky caught my eye so I grabbed the camera for a photo. Check out that lower left corner. The jets must have been busy this morning.
From Wikipedia: “Contrails; short for “condensation trails” or vapor trails are long, thin artificial (man-made) clouds that sometimes form behind aircraft. Their formation is most often triggered by the water vapor in the exhaust of aircraft engines, but can also be triggered by the changes in air pressure in wingtip vortices or in the air over the entire wing surface. Like all clouds, contrails are made of water, in the form of a suspension of billions of liquid droplets or ice crystals.
Depending on the temperature and humidity at the altitude the contrails form, they may be visible for only a few seconds or minutes, or may persist for hours and spread to be several miles wide. The resulting cloud forms may resemble cirrus, cirrocumulus, or cirrostratus, and are sometimes called cirrus aviaticus. “Camera: Nikon D7100 – Lens: Nikon 18-300mm

Glad that you stopped by my self-project of a photo a day for 365 days. If this is your first time to my site and you wonder what this 365 days of photos is all about, click HERE to read the original post. Settings are added to the photos so that I can remember what I’ve used and can see if any future photos done with other settings turn out better or worse. Remember, this project is all about my learning more about photography.
