Ghostly mobile phone view of Castor

Trying to conserve depleted camera battery in low temperatures I took this ghostly view of my son Keith with my mobile phone on the way to climbing SW flank of Castor; in view beyond. Spindrift is being blown through the col between Castor and Pollux behind Keith, by powerful winds. With a temperature of -10 centigrade there was quite a wind chill effect and we were having a last break in an oasis of relative calm, before being fully exposed to the elements all the way to the summit. 11th September 2014.
