Rectangular to Polar

April 2nd, 2011

Take your panorama, convert from rectangular to polar coordinates, and you got yourself a little sphere world.

I photographed the FEASTival, as part of the live arts Fringe festival this year. It invites the big shots of Philadelphia’s restaurant scene to set up tables. I got to meet Stephen Starr, Jose Garces, Michael Solomonov etc. Mayor Nutter and Ed Rendell were also present for me to snap some shots of. Besides all these famous people and delicious food though, what I enjoyed was the performers on the ceiling hanging on wires dancing above the crowd.

one second film, two hour photo

September 1st, 2010

This is a concept that has been in my head for a long time and I’ve finally managed to try it out. To capture the full sunset multiple images were composited together to form this photo. Some parts of this image show clouds during daylight, while other parts show high-rises late in the night. No longer do my photos capture only a fraction of a second. This image was made over the course of a couple hours.

A cookie in photography is short for cookaloris. It’s a technique where you shoot your flash through something with holes so the light that goes through creates a textured shadow. For example you can aim your light source at a piece of plywood, that has a bunch of random cut holes like this. Instead of an evenly lit background you can achieve a more varied image with shadows and highlights.

I like to use natural light as much as I can. In this one I’ve consciously used the shadows created by the sun coming through the trees as basically a gigantic cookie. Highlights and shadows create a patterned texture on the grass adding lots of depth to this photo. The red and green make for a great contrast. Flashes coming in from left and right, both at 1/2 power. One light to highlight Falon’s wavy hair and another one to create a rim light on her long legs.

It’s fun to shoot in old warehouses. You can walk around and discover cool little spots to photograph everywhere. We’re in front of an old freight elevator here which I thought would make a great backdrop.

I like the way the light falls on Amber’s hair. A little more than just a rim light, but not too much and some shadows are being cast on her face. Speedlites camera left and right. I forget what settings. Oops!

The Robot Etudes

May 10th, 2010

This blog usually functions as a journal for my photography endeavors, but I’m quite excited about this next project and figured it’s somewhat related that I decided to throw it in.

For the past three months architects and engineers students at the University of Pennsylvania have been working together on building mechatronic devices (think robots) to interact with actors in a play. Etudes were created and are loosely inspired by Shakespeare’s Midsummer Night’s dream. They will be performed this Saturday by the Pig Iron Theatre Troupe at the Harold Prince Theater of the Annenberg Center.

The very avant-garde Pig Iron Theatre Troupe is highly renowned so we are lucky to work with them and Shakespeare was a rad hipster in his day so brush up on themĀ here and here.

Being a roboticist by day and photographer by night I’m always interested in mixing the art and engineering disciplines. Often though when I look around and find these two disciplines combined it dilutes the two and the sum is less than the parts. The result usually being mediocre engineering and crappy art. It is difficult to find the right balance in which one discipline not only does not take away from the other, but that it actually enhances.

Adding technology may be fun for engineers, but may not work theatrically. What architects want to do, may not work engineering wise. Were we able to additively combine engineering with architecture with theatre? I’ll let you decide for yourself. Reserve your tickets here.

Private Show

March 10th, 2010

Photographers always get front row seats. Or we get to hang out backstage with the band. But what’s best is that sometime we get hired and get our own private show.

The Sastras

Meet my parents and my little brother. From left to right: Budiman, Marijetti and Johnny Sastra.


You must see these at higher resolution: papa, mama, the prince.

kids always steal the show

December 7th, 2009

The great things about kids is that they are so expressive. They seem to be in their own little world. Unlike grownups they don’t mind getting their picture taken. They’re not so self conscious and they’re usually not that shy.

I like to get down on one knee when I photograph them to make myself shorter and see the world from their perspective. This little man below was being spun around by his dad. I tried blurring the background to emphasize that.

Slow and steady sunset

November 24th, 2009

About two weeks ago I went to PDMA, a conference about innovation and I saw Guy Kawasaki speak about curve jumping: adopting the latest and greatest piece of technology to stay ahead of the competition. The analogy in photography is to find the newest piece of hardware, whether it’s a lens baby, some new light modifier, a lens with ultra sonic motor and built-in solar panels, who knows what’s next. It always takes time to learn how to use your new toys, and usually the learning curve is pretty steep. So it’s very tempting to get new toys because it can complete change your photography instantly. However, lately I’ve found it’s more important to be perfecting what I’m already doing.

So in this photo I have no new gadgets. Just trying to perfect this style of one flash to highlight the face, and what I call hyperreal post production. Hyperreal post production is when I load a picture into Photoshop and play around with the sliders for an hour. I don’t exactly understand how they manipulate the bits, but I’m getting a good intuition for some of them. Also my eye gets more sensitive to slight changes. Slow but steady progress.

This photo was taken at sunset. It is considered by many photographers the perfect time of day.
