Since 1963, Dr. Guertin has been viewing and photographing total eclipses of the sun, having been clouded out in only 5 of 24 eclipse expeditions (20 total, 4 annular).  More than 200 of Jacques’s high-resolution photographs of the chromosphere, prominences, and inner corona have been published in magazines such as Astronomy and Sky &Telescope.  Jacques has also organized and led groups to difficult eclipse locations such as deep in the middle of Borneo (1988) and the Sahara (Niger, 2006), and Atka (Aleutian Island, 1990).

Besides eclipses, Jacques has extensive experience in nature photography, and in-depth knowledge of cameras, lenses, and telescopes.  Jacques provides suggestions on how to photograph various features of a total solar eclipse using a digital camera as well as a traditional camera using photographic film.
