it’s been rather quiet in the blog lately, so i thought i’d share a peek into what we’ve been up to at work:

Hydraulic vulnerability analysis using X-ray microCT
MicroCT cross section of a Eucalyptus stem. One of the major points of critique for hydraulic measurements of xylem vulnerability and embolism is that they are destructive measurements. In contrast, non-invasive imaging has made it possible to observe xylem function and the spread of embolism in living, intact plants without destructive sampling and associated artefacts.

In collaboration with Iain Young and Richard Flavel at the University of New England, Armidale, we recently scanned the stems of young Eucalyptus trees at high resolution using X-ray Micro Computed Tomography (microCT) to visualize the loss of hydraulic function at increasing levels of drought.

[updated & simplified] how to convert an .avi file for use in gopro studio, using only freeware more than a year ago, i published the article how to convert an .avi file for use in gopro studio, using only freeware, which has apparently seen quite some interest. recently, the article has accumulated more and more comments about problems following the tutorial. after a fresh install of Windows and GoPro Studio, the Cineform HD codec is indeed no longer available in MPEG Streamclip.

here’s an easier method of converting non-GoPro videos for compatibility with GoPro Studio, which has worked for me. [more…]

below, you see a resized version of a 45 megapixel night sky panorama recorded in toorale national park near bourke, outback new south wales, australia. the image is composed of 24 individual 30 second exposures at f/1.8 and ISO 1600 taken with the Sony RX100 (mark 1), a compact camera that continues to impress me even after almost three years of frequent use. the panorama took almost an hour to record.
