This was taken at a small lily pond using aperture-priority mode. I chose to shoot a lily among the leaves to give it a fresh feeling.

You wouldn't want that nasty virus hanging out with your blood cells... Inspired by the popular Dual Neuron wallpaper.

I used procedural textures in Cinema4D and turned everything to max!

A great photo spot at Natural Bridges State Park outside of Santa Cruz, California. I used my Nikon D3100, Sigma 10-20mm, lens, some cheap GND filters and a tripod. I had to time my photo within the sets so the tripod didn't get knocked over.

The Eastern State Penitentiary is a former American prison in Philadelphia, Pennsylvania. It is found at 2027 Fairmount Avenue between Corinthian Avenue and North 22nd Street in the Fairmount section of the city, and was operational from 1829 until 1971. The penitentiary refined the revolutionary system of separate incarceration first pioneered at the Walnut Street Jail which emphasized principles of reform rather than punishment.

Notorious criminals such as bank robber Willie Sutton and Al Capone were held inside its innovative wagon wheel design. At its completion, the building was the largest and most expensive public structure ever erected, and quickly became a model for more than 300 prisons worldwide.

The prison is currently a U.S. National Historic Landmark, which is open to the public as a museum for tours seven days a week, twelve months a year 10 am to 5 pm.
