Focus.

Another picture from Saturday morning which, again, illustrates the magic of human eyeballs.

This is a photo taken through the Mini's glass sunroof of the ice crystals that had formed rather charmingly on it. My eyes were easily able to focus on them, and see them as white - but I could not get the camera's auto-focus to understand what I wanted it to look at; so it sensibly decided it must be the tree branches overhead. The ice crystals that are the most in focus also look dark grey against the blue sky, instead of the frosty mix of white and clear that they looked like to me.

That's ok Little Camera, it's still a pretty picture!
