Tornado op de zon

Here’s something you’ve probably never seen before. For a 30 hour spell – on February 7 and 8, 2012 – NASA’s Solar Dynamics Observatory captured plasma caught in a magnetic dance across the Sun’s surface. The results closely resemble extreme tornadic activity on Earth. A solar physicist at NASA said the tornado might be as large as the Earth itself and have gusts up to 300,000 miles per hour.

Examples Of Brilliant Tilt-Shift Photography

Tilt-shift photography refers to the use of camera movements on small and medium format cameras, and sometimes specifically refers to the use of tilt for selective focus, often for simulating a miniature scene. Sometimes the term is used when the shallow depth of field is simulated with digital post processing; the name may derive from the tilt-shift lens normally required when the effect is produced optically.

Here are more than 100 examples of brilliant tilt-shift photography.
