It was a beautiful morning today, with bright blue skies shimmering over Bernal Heights.

I caught this view about an hour ago, through the window of a southbound Caltrain which was “wrapped” from end-to-end with an advertisement for a popular smartphone.

In practical terms, this is Caltrain’s version of a photo filter, and its effect on my view of Bernal Hill was oddly pleasant.
