At the South Pole
I started experimenting with photography and darkroom processing during my early teenage years. I would photograph the Moon and planets as well as sunrise and sunsets with my Nikon EM. Several decades and Nikon camera bodies later I continue to photograph the sky as well as experiment with different photographic techniques such as time-lapse, infrared, high-speed flash, and fisheye photography for full-dome projection. My photographs and time-lapse sequences are featured in some of my films as well as in some Adler Planetarium productions (both fiull-dome and 3D shows). They have also been featured on CNN as well as on many productions by the BBC, the National Geographic, and Discovery Channels.
I hope my photographs make people want to learn about what they see in them. It could be Prague or the Milky Way. I am happy as long as the images inspire people to learn about something new. You can view my photographs by SUBJECT or by LATEST UPLOADS to Flickr.


Observatories Around the World

The first astronomical observatory I photographed was the Arecibo Observatory in Puerto Rico. I photographed it several times during my years there as an undergraduate and graduate student in the 90s. In 2008 I started systematically photographing the most important observatories around the world such as the Mauna Kea Observatories in Hawaii and Cerro Tololo Inter-American Observatory in Chile. To date I have visited almost 30 sites in five continents.
In August 2009, as a result of my growing reputation as an "observatories" photographer, the European Southern Observatory (ESO) invited me to photograph their telescopes on Cerro Paranal, Chile. This successful commission prompted similar requests from the University of Chicago to photograph observatories in California and Chile, and additional requests by ESO. The latter named me an ESO Photo Ambassador in August 2010 in recognition of the “astonishing [captured] views of ESO sites and the Chilean skies”. In November 2011 I spent nine days in Antarctica, including five days at the South Pole, photographing the South Pole Telescope for the University of Chicago — my most challenging photo assignment to date.
Below is my Observatories Flickr set (iPhone and iPad users should use link instead) and a table listing the sites visited and the telescopes photographed so far. Observatories visited in the 90s were photograped with Nikon film cameras and those images have not been scanned yet. Images from some observatories photographed as recent as a few years ago remained unprocessed, hence the lack of links to those subsets.

Introduction to Time-lapse Photography

Mauna Kea
I shot my first time-lapse sequence on Mars Hill in front the Parthenon in Athens in 2007. One year later I was enhancing those techniques by shooting in stereo (3D) for a film I was producing for the Adler Planetarium. Since then I have made six films that have benefit from shooting events that occur too slowly for the human brain to perceive and compressing them in time (eg, the apparent motion of the night sky, cloud formation, plant growth). In 2011 I designed a course for Calumet Photo in Chicago in which taught how to take time-lapse sequences, how to process them, and how to edit them in a coherent piece of work. This workshop is coordinated by KV 265

Teaching Science and Art through Photography

High-speed flash photography
Photography lies at the intersection of science and art since a camera can be an artist's tool as well as a scientist's imaging device. In this workshop we explore how photographic techniques such as time-lapse, high-speed flash, and infrared photography can be used to not only create artwork but to learn (and teach!) about science concepts such as electromagnetic processes (eg, emission, reflectivity) and perception of time. We also take a look at how the resulting photographs can be combined with music to make short films that bring science and art together. This workshop was first given to thirty teachers in Anchorage, Alaska in January 2012 and it is coordinated by KV 265.

Broadcast, Publications, and Exhibits

Some of my photographs have been published in magazines and science books, and shown in cities such as San Juan, Chicago, San Francisco, Belgrade, Piestany (Slovakia), and Paris. I have contributed animations and time-lapse sequences to documentaries produced for the History, Discovery, BBC, and National Geographic channels. Also, I have been a Photoshop Guru Award finalist twice for my photocomposite work.
