185. Midnight Sun

On December 21st I posted a picture taken in the middle of the day to show how dark it was. To balance it out, here is a picture taken in Deering in the middle of the night on the longest day of the year. (Chip e-mailed it to me. He is not sure why the sun came out black.)

This is beautiful! The black sun looks very dramatic.
the black sun (if this was taken with a digital camera) is a result of intensity thresholding. The sun is too bright for the CCD (charge coupled device) that registers photons in a digicam, so it sets a "threshold" for maximum light intensity in an image and anything above that goes to black. (this happens to my cells if I overexpose them with the fluorescence camera)
