A tree appears to radiate as cracks across the foundation of the base of the western span of the San Francisco Bay Bridge.
A heavily pollarded tree stands in front of the blue sky broken by one expanding contrail, Golden Gate Park Music Concourse, San Francisco, CA.
Photo notes: This is actually an HDR photo using a high contrast naturalistic filter. Using HDR this way increases detail and clarity without increasing noise.
I usually don’t go for the full HDR look, but I thought this Danger, Will Robinson style robot at the 2013 Maker Faire looked cool with the HDR and tone-mapping turned way up.
Edit: As Lael Rapier from G+ pointed out, this is #Dalek from Dr. Who. I’ve only watched a few minutes of Dr. Who so I had no idea.
