Mount a camera on a tripod, point it at the heavens, and open the shutter, and you can capture an image of curving streaks of starlight that reveal information about our planet and its position in the solar system. I have made such time exposures of space from Earth, so when I had the chance, I figured it was only fitting to make time exposures of Earth from space.]]> 2020-10-13 02:41:51 UTC https://padlet.com/jharia/x8b9w7qysuyg2uzo/wish/823456282 jharia https://padlet.com/jharia/x8b9w7qysuyg2uzo/wish/823456757 Human eyes can only see a limited slice of the full electromagnetic spectrum. Just beyond what we see as deep red at one end of our “visible spectrum” is infrared radiation, wavelengths that are rich with information about our environment, but escape our detection.... In this infrared photograph, lush green plant life appears as bright orange-red. Rocky crags and other barren geologic structures appear as dark green to blue-grey. Turbulent oceanic currents become visible as whitish veils, and coral reefs glow a tie-dyed yellow-green]]> 2020-10-13 02:42:08 UTC https://padlet.com/jharia/x8b9w7qysuyg2uzo/wish/823456757 jharia https://padlet.com/jharia/x8b9w7qysuyg2uzo/wish/823458355 From space I have been able to capture wide-angle oblique views of natural structures on Earth that stretch across half a continent, and telephoto views that showcase fine details. Light is the heart of these photographs. Low-angle sunlight casts long shadows, and gives depth. Noontime sun creates sun glint, intense lighting that causes surface water to act like a mirror directly reflecting the sun’s rays into the lens. Sun glint reveals ocean surface patterns that are invisible under any other lighting condition.]]> 2020-10-13 02:43:06 UTC https://padlet.com/jharia/x8b9w7qysuyg2uzo/wish/823458355 jharia https://padlet.com/jharia/x8b9w7qysuyg2uzo/wish/823461653 "Apart from everything else an astronaut does on orbit, photography is actually part of our job."
