My old pal Leptothrix discophora came out to play in the parks earlier this month. This photo was taken in a sweet lagoon of the Venice Myakka River Park.

The small patch of Leptothrix discophora film in the bottom left of this photograph gives you a taste of the run of images that starts tomorrow on this blog.

Birth of an Obsession

July 7, 2017

Kendal at Oberlin publishes a literary magazine, called Eureka!, three times a year. All the artwork and writing is by residents of this retirement community. I’m lucky enough to live at Kendal at Oberlin, and to have had an article with photographs published in the latest issue. The piece reveals the origins of my fascination with the iron bacteria. Since many of you have seen on this blog my photographs of the iridescent film that Leptothrix discophora creates on the surface of water, I thought some of you might be interested in reading about how my engagement started. Just click on the link below to find out. And please forgive my crude post-production edit on the next to the last page. I thought it made the story easier to understand. Below the link to the article is a photo of Leptothrix discophora film that I took last month at Schoepfle Garden.
