America’s Presidents

The renovated #AmericasPresidents exhibit reopens today at @NPG.Smithsonian with some excellent new digital content!
http://npg.si.edu/exhibition/americas-presidents-reopens

After 18 months of planning and extensive renovations, “America’s Presidents”—the National Portrait Gallery’s “must see” exhibition—reopens to the public Sept. 22. As part of the reopening, a selection of sculptures from the exhibit were 3D scanned and have been made available to view, download, and 3D print.  Explore the collection here: https://3d.si.edu/browser/NPG_Presidential_Portraits

8-hour Shootout: A Digitization Showdown

The scene is set: capture 3 objects from the Freer|Sackler Gallery’s Chinese bronze collection with 3 different methods in 8 hours.  Our protagonists stand before us: 4 members of the DPO staff with sharp eyes and willing hearts.

Max Anderson is armed with an automated photogrammetry rig and enough flash power to blot out the sun.  His system leverages 4 50mpxl cameras, a set of strobes with softboxes and bounces to soak the scene in light, a turntable set to 10 degree intervals, and a light absorbing backdrop to make the objects appear to float in space.  The system has a proven throughput of 15 minutes per side, for a total 288 (252) captures in 30 minutes.  -  Jon Blundell stands alongside Max with a hand-held photogrammetry setup with polarizing filters to eliminate shine and enhance color.  His system is the only one unhindered by the shine of buffed bronze, and he can move at as fast a pace as his flash will fire.  

In Joe Conrad’s holster is a laser arm scanner capable of recording fine surface details without color. The 7 axis arm allows Joe to access tight nooks and crannies other won’t be able to get to.  This machine has a surface accuracy up to 35 microns and is the most agile of the methods.

Meg Dattoria stands beside the heaviest hitter in the game: the structured light scanner.  It is a beast of precision but unfortunately, also a beast to operate.  Each capture position must be meticulously dialed in, and on this machine the vibration of a near by footstep is enough of a disturbance to cause a capture to fail. She will utilize a turntable and adjustable studio stand to deftly maneuver her way around the objects without disturbing them.


In a cramped room behind the Freer|Sackler Galleries, members of the Digitization Program Office face off, each armed with a different scanning tool.  When the dust settles, who will have the best data, and at what cost?..
