When I first developed the method to estimate canopy metrics from smartphone spherical panoramas, I used a somewhat convoluted workflow involving command line image manipulation, a plugin for ImageJ to […]
Spherical panoramas can be tricky to stitch properly in dense forests, and especially when canopy elements are very close to the camera (which exaggerates the parallax). Fortunately, the issue attenuated […]
Our newest paper (pdf available on my publications page), led by Kaija Gahm is just out in the Journal of Experimental Zoology as part of special issue on herp physiology […]
Hemispherical photography is one of those tasks often prefaced by the statement, “How hard could it be?” I’m pretty sure I said something like this at the beginning of my […]
At this year’s Evolution Conference in Providence Road island, the organizers managed to recruit volunteers to film most of the talks. This is such a great opportunity for folks who […]
Among other topics, my lab studies the relationship between forest obligate frogs and urbanization. During a seminar, I once heard my advisor mention that Connecticut is the perfect state […]
Now that you’ve got the theory, equipment, and your own hemispherical photos, the final steps are processing the photos and generating estimates of canopy and light values. We’ll be correcting […]
I’m currently on my way up to Alaska for another supremely short season of guiding (just two trips this years). I was going through some old photos and came across […]
I’m getting really excited about a project I’m working on that will visually compare the way various animals see their habitat. This is part of a Digital Education Innovation grant […]
This is my second technical post on using hemispherical photography for light estimates. My previous post considered the rationale behind hemispherical photography estimation methods. This post will cover hardware, specifically: […]
