Babbage Difference Engine in Gigapixel

In July of 2012 xRez Studio was contracted to shoot a unique “close up” gigapixel image of the Babbage Difference Engine  at the Computer History Museum in Mountain View, California. The “Difference Engine No. 2″ was never realized or constructed in the lifetime of famed mathematician and inventor Charles Babbage. However it was funded over 150 years later by former Microsoft CTO Nathan Myhrvold.

CARBON-X Fulldome Film

xRez Studio’s Eric Hanson has completed an experimental film collaboration with SETI artist-in-residence artist Charles Lindsay, entitled CARBON-X. Designed for the planetarium fulldome format, it was a component of an arts grant program entitled Getting Off The Planet, through Ecoartspace curator Patricia Watts. It premiered at the ISEA 2012 Conference, Machine Wilderness at the Intitute for American Indian Art’s Digital Dome in Santa Fe, New Mexico.

Join us! New Free Forums for the RTI Community

This week we are rolling out CHI’s new free forums  for the community of people who are developing and adopting Reflectance Transformation Imaging (RTI) and related computational photography. We have had the idea to do this for some time, and after trying a couple of different forum software packages, getting input from friends, and tinkering with some of the forums setup, we are now ready to invite the larger community. Join us! Sign up for a forums account now: go to http://forums.

Griffith Planetarium- Time’s Up

xRez partner Eric Hanson recently provided several key CGI sequences for Griffith Planetarium‘s new fulldome visitor film, “Time’s Up“. The film explores the nature of time in the universe, from human to cosmic scales.

Yellowstone Supervolcano VFX

xRez Studio has completed CGI and time-lapse work for Supervolcanoes, a fulldome film for digital planetarium distribution and directed by Thomas Lucas of Dynamic Earth and Black Holes fame. Helping describe the occurrence of past geologic massive volcanoes, the work encompasses visualization of the remnants of the Yellowstone Caldera, a past volcanic event that sent ash as far as Los Angeles.

CHI celebrates 10 years as a nonprofit corporation!

On August 16, 2002 we founded Cultural Heritage Imaging as a nonprofit corporation in San Francisco.  Wow, it seems like yesterday and it seems like a long time ago!  Our digital camera at that time was 3 megapixels and it had a pretty slow auto focus. We had seen Tom Malzbender’s pioneering Polynomial Texture Mapping paper at SIGGRAPH in 2001, and we began working with him several weeks later.

Everest Base Camp Trek 2012

xRez partner Eric Hanson was contracted by Glacierworks to document the rich cultural and on-trail experience of the Everest Base Camp (EBC) trek in the timeless and spectacular Khumbu region of Nepal during the 2012 climbing season.

We’re going to Somerset – Come along!

Next week, from the 16th to the 20th July, the Re-reading the British Memorial project team will be in Holcombe, Somerset, working with Wessex Archaeology, the Churches Conservation Trust, Somerset Archaeological and Natural History Society, Somerset County Council. We will be supporting a series of activities taking place at St Andrew’s Church, Holcombe, Somerset, as part of the Festival of British Archaeology.

Zero Out Settings

During the post processing phase, when you open your DNG files in Adobe Camera Raw (ACR), you have an opportunity to adjust your white balance and your exposure compensation. Prior to making these adjustments … We recommend that you create a “Zeroed Out Settings” custom preset, and apply it to the entire image set. Consider making this your default preset for Adobe Camera Raw.

Free RTI Workshop!

The team here are very excited as we are putting plans in place to host a free workshop for all interested organisations and groups to come and visit the University of Southampton and try out some of the low-cost and free technologies that we’ve been testing with our project partners. The workshop date has yet to be confirmed, but we are anticipating that it will be held in August-September 2012.

Royal Garrison Church, Portsmouth

Visiting Royal Garrison Church Last week, Gareth, Adam and I travelled to Portsmouth to work with the team there on recording some very challenging memorials. The Royal Garrison Church in old Portsmouth, maintained by English Heritage and a dedicated team of volunteers has an impressive situation.  Nestled behind the sea defensives and located near to the historical dockyards and harbour front of the old city of Portsmouth, the church was built in the thirteenth century.

Reconnaissance. Scouting. Preparation.

Reconnaissance. Scouting. Preparation. Marlin Lum here. Imaging Director at Cultural Heritage Imaging. This blog entry inspired by Mark Christal, strong man and multi-media super genius employed by the National Museum of the American Indian (NMAI) at the Mall in Washington DC. It’s part of his professional game to find out as much as possibly about a topic and then present it to the public via modern visual technology.

RTI Experimentation with a Copper Breastplate in the Florida State Bureau of Archaeological Research

This is a Guest Blog by Photographer Joseph Gamble. As an affiliate with the University of South Florida’s Alliance for Integrated Spatial Technologies, I traveled with a team of archaeologists doing imaging research and 3D laser scanning of artifacts to Tallahassee last year to work in the Florida State Bureau of Archaeological Research (BAR) and experiment with RTI on a number of Native American artifacts from Lake Jackson, Florida. AIST Directors, Drs.

Canon Vs Nikon

I was recently asked, ‘What DSLR camera is better for RTI data capture? ‘Canon or Nikon?’ The answer is like Godzilla Vs King Kong. Its gonna be a good fight. The Short Answer is that either camera will work. In the hands of a professional photographer, they are both very similar.

iPhone RTI

I have been spending quite a lot of time lately working with Reflectance Transformation Imaging (RTI). It is a computational photography technique developed by Tom Malzbender at HP labs. It is based upon photographing an object from a fixed camera position, in each image the lightsource is moved. These images are then compiled into an interactive image within which the light can be virtually moved.

Experimental Microscopic RTI Dome

by Guest Blogger Eleni Kotoula, PhD student, University of Southampton, Archaeological Computing Research group Application of normal and microscopic RTI to artifacts derived from the Hellenistic-classical Derveni cemetery in Macedonia, Greece, demonstrates RTI’s contribution towards prevention, investigation, documentation and communication.

RTI Example – St George’s Church, Portland

We’ve been looking into how RTIs can be best shown through the web. In the same way that a video needs to be opened inside a video player, to view an RTI as an interactive experience, an RTI viewer is usually installed onto the computer of the person who wishes to open the file.  But there are some great web-based options being developed that will allow users to view RTI files within their internet browser.

CAA2012 Conference Presentation

On the 27th March 2012, we presented the Redicovering Our Churches project at the Computer Applications in Archaeology 2012 conference at the University of Southampton.  We’ve uploaded a copy of the powerpoint presentation into Slideshare.  It doesn’t have a copy of the script, just the slides, but we thought it would be useful to share the content with you all.

St George’s Church, Portland

St. George's Church, Portland We recently visited St. Georges Church on Portland in order to demonstrate RTI techniques to a team from Wessex Archaeology who were working to document the church and its associated cemetery, you can read more about  work that they are carrying out with the Churches Conservation Trust on our Other Projects page. The project held particular personal interest to us as the church had previously been the parish church for several generations of Nicole’s family.
