Behind the Scenes: Museum Photography at the Oriental Institute

Recently Anna R. Ressman, Head of Photography at the Oriental Institute Museum, University of Chicago, shared a compelling article with me, and now I’m sharing it with you. Here is a link to the Oriental Institute newsletter (PDF), which contains the article entitled, “Behind the Scenes: Museum Photography at the Oriental Institute.” Anna describes the process in which five very different artifacts are documented, each with a unique challenge.

Greek red-figure vases, two surface examination methods and fabricated mock-ups

Paula Artal-Isbrand and Philip Klausmeyer recently published an article in the Studies in Conservation journal. Entitled “Evaluation of the relief line and the contour line on Greek red-figure vases using reflectance transformation imaging and three-dimensional laser scanning confocal microscopy,” the article examines “…the relief and contour lines on a group of ancient Greek red-figure vases and vase fragments.

CHI Welcomes Tom Malzbender to the Board of Directors!

Tom Malzbender imaging a piece from the Antikythera Mechanism We are absolutely thrilled to announce that Tom Malzbender has joined the Cultural Heritage Imaging Board of Directors! Tom is a long-time friend of CHI and has been an adviser and collaborator on many projects. Tom is best known as the co-inventor (with Dan Gelb) of Polynomial Texture Mapping (PTM) in 2001 while he was at HP Labs. PTM is the first form of Reflectance Transformation Imaging (RTI).

Autodesk Photogrammetry Capture for Maya 2015 Launch

  In October 2013, xRez Studio was contracted by Autodesk to capture spectacular landscape features of our choosing to be used for content promoting an upcoming launch of Maya 2015. We suggested 2 primary sites, the sand tufa formations at Mono Lake in the Eastern Sierra, and the wind-carved sandstone formations at Valley of Fire in Nevada.

NEW: RTI glossary now available

Over the years we have received a lot of requests for a glossary of terms used in RTI, and we are happy to announce that a new “Glossary of Photographic and Technical Terms for RTI” is available on our website!  It includes photographic terms you need to know for RTI, like “Depth of Field,” “Color Temperature,” and “Aperture.

Workshop in York – 15th May 2014

We are very excited to announce that the Re-reading the British Memorial project is going north and will be holding our next workshop in York on the 15th May. The workshop will form part of a larger event called ‘Saving your Cemetery or Churchyard’ and will be held at Kings Manor (the Archaeology department of the University of York).

A big thank-you to our donors!

What an encouraging way to end 2013: our Annual Giving campaign raised almost twice as much as the previous year! Our donors’ continued support of Cultural Heritage Imaging (CHI) is both touching to us personally and vital to our mission. Our donors’ gifts enable CHI to develop innovative digital imaging tools and practices and disseminate them to experts and students all over the world.

Feeling Gray? How about some Shades of Gray?

Feeling gray? How about some shades of gray? Have a new studio? Want to paint it photographic neutral gray? Read on for important information and advice. The information quoted below was authored by Dan Kushel, Distinguished Teaching Professor Emeritus at SUNY Buffalo State, New York, USA. Recent photographic lab renovations at Buffalo State College required the walls to be painted a fresh coat of gray.

Hiroshima Peace Conference

In winter of 2011, xRez partner Eric Hanson spoke at the Hiroshima Peace Museum at a conference on utilizing digital media toward peace education. Meeting with filmmaker Mr. Masaaki Tanabe and TBS producer Norico Wada on our prior involvement with the Hiroshima Reconstruction Project while there, Eric was provided warm and  generous hospitality, being personally toured over several days to several deeply affecting historic sites surrounding this dark chapter of human history.

Spherical Antelope Canyon

Antelope Canyon is one of the most remarkable natural features in the Colorado Plateau, but is heavily photographed and takes little skill to derive an astounding image. We wanted to capture it spatially using spherical imagery to help describe the very complex sculptural forms contained within. Ultimately, we hope to reconstruct the two canyons with stereoscopy and full 3d modeling, but in 2010 we performed this series of panoramic captures as a scout.

Yosemite Spyglass for Oculus Rift & iPad

We love Yosemite and have found a few new ways to experience it in gigapixel on the iPad and Oculus Rift! The Oculus Rift version of Yosemite Spyglass is available for the Mac and PC.  The Yosemite Spyglass for the iPad is available in the Apple App Store.

Behind the scenes: RTIViewer 1.1 release

We are thrilled to announce the release of the RTIVewer  1.1 software! This update release includes the most asked for features in the RTIVIewer.  As with prior versions, this is free, open source software. We have been working with it for a while, and we are excited to get this out to everyone in the RTI community. I am most excited about surfacing all the numerical settings data within the interface.

Adam Rabinowitz’s blog post on digital surrogacy

Adam Rabinowitz’s Blog Post “The Work of Archaeology in the Age of Digital Surrogacy” is a brilliant thought provoking piece, and I couldn’t resist reposting here. At CHI we have been wrestling with issues of scientific imaging and process history and what it means to be a digital surrogate for many years.

Mysteries of the Unseen World

xRez was contracted by Day’s End Pictures to shoot stereoscopic time-lapse sequences for the National Geographic IMAX production of “Mysteries of the Unseen World“.   Released in November of 2013, the film reveals the stunning beauty and enormity of the world that is in front of us but cannot be seen due to the scale, time period, or electromagnetic frequency. The film uses high-speed, time-lapse, electron microscopy, and nanotechnology to reveal this unseen world.

Behind the Scenes of a New English Heritage guide for RTI

Guest Blogger: Sarah M. Duffy Ph.D. Serendipitously while completing my Master’s in Historic Preservation at University of Texas at Austin, I met Carla Schroer and Mark Mudge of Cultural Heritage Imaging (CHI) at the 9th Annual US/ICOMOS International Symposium being held in San Francisco in 2006 where they were demonstrating the application of an innovative recording technique based on a mysterious shiny black ball.

Thank You Tim Lindholm!

Tim Lindholm, circa 2004 I want to take a moment to thank outgoing board member, Tim Lindholm.  Tim served on the CHI board from its inception in 2002 and has been an enormous help to us over the years.  In addition to being a constant source of good questions and good advice on the board, Tim  designed the electronics and power systems of CHI’s early automatic dome systems.

Rock Art Recording

Mark shooting photogrammetry sequence at Petroglyph National Monument During the month of May we had the pleasure of doing more imaging work with Rock Art .  This has included shooting some Reflectance Transformation Imaging (RTI) and some photogrammetry sequences at a couple of different sites.  More importantly, we have had a chance to present some of this work to folks researching and recording rock art.

RTI workshop at Winchester Cathedral

On the 1st February the OuRTI team went up to Winchester Cathedral to help run an RTI workshop. The cathedral contains a range of highly important memorial inscriptions and is also home to a huge collection of graffiti spanning several hundred years. The event, organised by James Miles from the Archaeological Computing Research Group, aimed to help researchers and tour guides at Winchester Cathedral to use computational photography to document and to better understand these inscriptions.

In honor of Debbie Ward

In the summer of 2012 I lost a dear friend of more than 20 years to lung cancer. Debbie’s and my friendship began in the workplace in the late 80′s, and blossomed into so much more.  We hadn’t worked together in more than 20 years, and yet we stayed in close contact and got together for regular dinners every couple of months. Debbie was a remarkable person in many ways, but if you asked her what the most important thing she ever did was, she would say being a mom to Katie.
