My interest in photography started in high school, where I shot BW photos for the Punahou School newspaper and year book. There were no computers and we did all our own darkroom work (developing film and printing images). My camera then and for many years after was a 1960s vintage Nikkormat SLR.

I moved to digital in 2002, and now have a couple cameras and photo printers. Digital photography is liberating, and has greatly changed the way I use photography to document and explore the world.

I think of my mathematical and computer graphic work as primarily photographic in nature. In particular, images of the Mandelbrot set (and other fractals) are like windows looking in on fantastic island worlds, which have real and fixed (although infinitely deep) geographies.

    "Roddh's photos are frequently influenced by a fresh look at the visual world that I enjoy. His thoughtful responses to my comments inspire me to think about why I post a picture. His awareness of Chaos Theory and Fractals contribute to a vision of Metapatterns in nature and awareness of the underlying construction of the physical world."

    "For me, roddh is the perfect illustration of a model Flickr user.

    He uploads on an almost daily basis, and always takes the time to add titles, tags, and descriptions. He covers a wide variety of subjects ranging from nature to computer generated imagery, with a strong dose of art and architecture. He seems to have a natural instinct for photography, and has a very good eye for lighting and composition.

    If you're looking for a steady stream of high quality, interesting photos, be sure to add him as a contact!"
