Cold!

Lamar Valley, Yellowstone at -25
When running low on wildlife photo opportunities Yellowstone always provides plenty of others. We were shooting ice and frost patterns along the Lamar River last week with the usual +1 .5 compensation to get the exposure right with snow and bright lighting conditions, when I decided I wanted to emphasise the cold by using super blue.
In this photo I am showing the blue light of super cold while still preserving the true white of the snow.
How?
Change the white balance to tungsten in camera then use the white balance picker on a bright piece of snow to keep the snow white.



Where dd all the animals go?
