Officially, the bythom.com site has been active since 1998. It was set up to support my first photography books (Nikon Field Guide, Nikon Flash Guide).
Prior to that, I was doing Nikon SLR user support in an Internet newsgroup, dating all the way back to 1994.
This site went hyperactive when I left Rodale in 2001 and devoted my full time and attention to my own photography and writing. In 2011 and 2013 I started additional sites, sansmirror.com, filmbodies.com, and gearophile.com, in order to reduce the number of topics covered by one site.
