Tuesday/ the northern lights

Posted by Tim Durkan @timdurkan on Twitter: Some beautiful Aurora borealis over Seattle tonight.

He says the further out of the city, and to the north, the better, for pictures like this. It needs to be clear and dark (places like Whidbey Island, Anacortes).

The camera that he used is a Fujifilm GFX 100S medium format* mirrorless camera (with a monster 102 MP 43.8 x 32.9mm BSI CMOS Sensor, able to catch faint variations in color in the night sky).

*Medium format means larger than the standard 35mm film format, which is 24mm x 36mm (864 mm2 of film surface). The Fujifilm GFX 100S’s sensor size is 1 441 mm2. By comparison, the new iPhone 13 Pro’s built-in camera (that takes spectacular pictures, by the way) has a sensor that is all of 35.2 mm2, which is 40 times smaller than the one in this medium format digital camera.
