For example, a product review I did in December of 2014 led people to the product on Amazon via an affiliate link. That product sold extremely well, and people also bought other things well they were shopping. That affiliate link earned me a pretty penny. Of course, that’s not always sustainable. In January and February I earned $300 and $400 respectively from affiliate sales. In March, I only earned $50.
Finally I promised one little girl, who made a long journey to see me and prefer her request, -- and she is a "Dorothy," by the way -- that when a thousand little girls had written me a thousand little letters asking for the Scarecrow and the Tin Woodman I would write the book, Either little Dorothy was a fairy in disguise, and waved her magic wand, or the success of the stage production of "The Wizard of OZ" made new friends for the story, For the thousand letters reached their destination long since -- and many more followed them.
I have found Alessandro Bergamini's China gallery to hit all the right notes in that regard. Most of his images were made in Guizhou; a province located in the southwestern part of the country, and well known for its traditional rural villages, inhabited by minority groups like the Miao and Dong. Other images in the gallery were made in Guangxi , another autonomous region bordering Vietnam, and home to the famous cormorant fishermen of Guilin. I haven't been but I read that even though the water is too polluted now for fishing to be sustainable, these fishermen are catnip for many photographers, and earn their living in that fashion.
