Chun the Unavoidable: Scholarly Publishing: The Invisible Adjunct has a post on a recent Chronicle article by Cathy Davidson on the crisis in scholarly publishing. Those of us in the field have been hearing a lot about this lately, from Lindsay Waters, William Germano, Stephen Greenblatt, and pretty much anyone else with an interest and/or brain. As I understand it, all research institutions and an increasing number of liberal arts colleges and comprehensive universities require assistant professors to publish a book before being granted tenure. Academic books do not sell, of course, and the university presses which publish them are coming under increased economic pressure….

Stefano Costa shares his view on open archaeology. We have a long way to go.

Very cool. I can show how to do this in Keynote or Final Cut.

In 1991 Griffin and Sabine became a worldwide phenomenon, and I was catapulted (kicking and screaming) into the limelight. However, for the twenty odd years that lead up to that rollercoaster ride, I’d been a full-time artist. So, in a sense, creating books was a sidetrack from my primary means of self-expression. Hence, in 2007 I decided to return to my painting roots. I opened my studio-gallery 'The Forgetting Room' here on Saltspring Island BC and set aside the pen.
During this passed Autumn and Winter I’ve been working on much larger paintings, partly because I now have the space and partly because it just feels good to open my wings. Some of these pieces have been under commission, others are simply for hanging in the gallery.

Stereo Photogrammetry

I added to the DropBox technote published by the BLM, authored by Neffra Matthews and Tom Noble. It describes aerial photogrammetry techniques and is simply rad.

To create the interactive images on this web site, Cultural Heritage Imaging (CHI) works with polynomial texture mapping (PTM), which uses reflection transformation imaging (RTI) technology. For more RTI and PTM details, visitCHI’s Technology section.

Greg Downing. You need to know about this guy.

This movie is a 3D model of the Berkeley BART station created from 4 digital panoramas.

A virtual set of the BART subway station in Berkeley California. A 12 second 8MB QuickTime movie.

This movie was created by taking 4 panoramas in the bart station. I created 3D models from the photographic panoramas and then textured the 3D models with the photographs. For more info on this process please look at my Tribunal Plaza.

Aproximate time to complete project: 5 days.

  • 1 day photography and panorama stitching
  • 1 day calibrating cameras
  • 2 days modeling and texturing.
  • 1 day editing and rendering

In image processingcomputer graphics, and photographyhigh dynamic range imaging (HDRI or just HDR) is a set of techniques that allow a greater dynamic range of luminances between the lightest and darkest areas of an image than standard digital imaging techniques or photographic methods. This wider dynamic range allows HDR images to more accurately represent the wide range of intensity levels found in real scenes, ranging from direct sunlight to faint starlight.[1]

The two main sources of HDR imagery are computer renderings and merging of multiple photographs, which in turn are known as low dynamic range (LDR)[2] (also called standard dynamic range (SDR)[3]) photographs.

Tone mapping techniques, which reduce overall contrast to facilitate display of HDR images on devices with lower dynamic range, can be applied to produce images with preserved or exaggerated local contrast for artistic effect.

Krishna Mohan explains how to use Photoshop CS4 to achieve focus stacking. Very cool.
