Analog Photo Fun- “Lomography”

My wife Sally and I just spent a week in New York City.  Good fun all around.

Congratulations to our friend Judy Jenson on her opening at Gerald Peters Gallery. (A great reason to visit the city.)   We had a wonderful time with our friends from Austin.

One day, after emerging from a Subway station on 23rd st, we noticed a cool store at 106 E23rd Street, NY 10010

It is a Lomography Gallery Store. http://microsites.lomography.com/stores/gallery-stores

I’d heard of Lomography and being photo geeks from way back, I/we had to go in.

A “few” dollars later we emerged with two plastic cameras which we immediately loaded with film and started shooting.

One camera, “Pop-9”, shoots 9 separate pictures at once in a standard 35mm frame.  The other was a wide angle camera called the “Sprocket Rocket”.

I also could not resist  the “Spinner 360” We went back to get that one too.    Here are a couple of pictures I shot with the Spinner:

The indoor shot was shot by rotating the camera body by hand.  The primary way to operate the camera is to pull a ring which which winds a spring. Letting go of the string spins the camera to take a shot.  It made me laugh the first time I shot a picture!

Here is a link to the main lomography website.

Cheers!

HD 3d Camera

Here are some photos of a full HD Stereo video camera I built using two Kodak Zi8 pocket cameras.  I built the case out of birch plywood and maple.  I choose the Kodak Zi8 camera because there was an optional remote control.  The cameras are linked to the remote with plastic fiber optics embedded in the frame.  This let me control both cameras with fairly accurate timing.

The width of the cameras was about 62 mm which is just about the right interocular distance.  I ended up with a final Interocular distance of about 65mm.  The cameras are quickly removable by lifting the hinged wood clamp.  Magnets are used to hold the clamp in place.  Rubber pads contact the camera at three points to get repeatable accurate positioning.  The pockets for the cameras were made carefully to get a nice close fit so that the stereo images would be as closely aligned as possible.  The two camera views are parallel and do not “toed-in” or converging. The tripod is attached at a point centered between the lenses using a 1/4-20 t-nut in the base.
We are using a free Windows program called stereo movie maker, which you can see here:

Here is a great primer on shooting 3d video from Tim Dashwood.

Sally and I presented the camera and some example videos at Dorkbot Austin on Monday January 24th at the at UT.  I built the camera for a project Sally is working on at the TACC visualization lab at UT.  http://www.tacc.utexas.edu/ The folks there have put together some fantastic visualization hardware and tools.  Check it out.  I’ll be adding a post soon with details on how I created the anaglyphic 3d video for the talk.

Here is a link to the video:http://www.youtube.com/watch?v=_UxQPMykqPo
