How
to Shoot 3D with a 2D Camera
Sunday,
June 22 couldn't have been a more perfect day to take the ferry to Governors
Island and spend time roaming around the island. It is a living museum of
American military history now converted into a modern park paradise. Among the
many attractions this summer is the summer home of the Holocenter, or the Center
for the Holographic Arts, located in Nolan Park, house #4B. Every two weeks
this summer The New York Stereoscopic Association has been
invited to feature a lecture about different aspects of stereography and its
long history. The first in the series was a presentation by John J. Zelenka called "3D
Right Between Your Eyes". John showed an enthusiastic crowd the basic concepts
and history of stereography from its beginnings in the early 1800s to
present-day, hand-held digital stereo cameras.
On
this Sunday, Gerald Marks delivered a
comprehensive lecture and demonstration called, "How to Shoot 3D with a 2D
Camera". He began by giving a brief history of stereography and his personal
involvement with the craft for decades. Then Jerry gave a presentation of his
personal library of stereo photos that were all taken with a 2D camera. These
even included photos taken of the moon and on the moon by astronauts, using the
classic "Cha-Cha" method. He then revealed how the "Cha-Cha" dance relates to
stereo photography.
After
the slide show, Jerry introduced Adobe Photoshop™ as his preferred tool to
create and edit stereo images. The assembled group posed for a photo on the
porch of house #4B as Jerry demonstrated the technique while holding a digital
camera.
The
group reassembled inside and watched as Jerry took the two raw images from his
SD card and quickly created a 3D image from two separate photographs taken with
a non-3D camera. He continued by demonstrating how to adjust the image in
Photoshop for optimal 3D effect.
Jerry
rounded out his generously robust session by offering anyone in attendance a
disk with the Photoshop files he had just created. As an encore, he treated the
remaining guests to a glasses-free stereo slide show on an auto-stereo computer
screen.
After
two successful guest lecture appearances at the Holocenter, The New York
Stereoscopic Association looks forward to the next event on Sunday, July 13 at 2PM by D. Carlton Bright
called, "3D from the 19th thru the 21st
Century".
