Tech bytes for tea?

Extremely realistic 3D imageries of people and places across 12 countries in 4 continents. I was amazed at the dimensionality of the imagery.

The free exhibition is from 14-29 March (10am to 7pm) at The Arts House.

The exhibition comprises a number of wall-mounted LG Cinema 3D TVs using battery-free glasses.

Each of the two cameras need to be aligned and adjusted manually for each shot.

Each TV showcases a different set of imageries taken by award-winning Stefen Chow for the international Denis Group, a Singapore-headquartered company established in 1862 which is celebrating its 150th anniversary this year.

The stereoscopic imagery were taken using a pair of Nikon D7000 DSLRs mounted on a slider which allowed the distance between the two cameras to be varied whilst maintaining the carefully calibrated alignment between the two cameras.

The slider was in turn mounted on a tripod for stability.

The whole contraption was custom designed and built after a survey and evaluation by Chow found the quality of 3D pictures produced by consumer cameras inadequate for his liking.

Improvised twin-barreled 3D shooting rig.

He did not use the higher-end Nikon cameras because the minimum distance between the two lenses – when the two cameras were placed side-by-side – were bigger than that needed in certain shooting situations.

For each imagery, every setting (focus, white balance, exposure etc) had to be put on manual to ensure both cameras produced imageries with consistent focus and exposure – so that they could be merged into 3D imagery.

Chow told me that the time taken to set up the rig and prepare for the shot took at least 30 minutes. In all, he snapped more than 700GB of imagery for the project.
