Harvey Stearn is a regular contributor to this website which is widely considered to be the largest and most important site devoted to photography. A listing of his articles as well as links to them can be viewed at www.luminous-landscape.com/author/harveystearn.
To completely read each article on that site it may be necessary (if the article is not accessed directly from this page) to be a subscriber for a $12 per year payment. It is up to the viewer to decide whether of not to join. However, most photography enthusiasts will find this modest fee to be a huge bargain. Luminous-Landscape (LuLa) offers thousands of articles on photography techniques, equipment, software, etc. plus tapes and tutorials and photography news.
For those who would enjoy reading my articles and viewing the photographs with minimal navigation, I will be re-formatting them for inclusion on this page starting in May 2018.
