Belgian photographer and trainer Piet Van den Eynde mentions the Promote Control in his new book ‘Pushing Light. Extending Dynamic Range with HDR and other techniques’:
“The Promote Control is the Rolls Royce of remote controls and highly interesting for HDR aficionados.”
The PDF ebook covers a broad range of techniques photographers can use to capture more dynamic range, features interviews with leading photographers about how they manage the problems of dynamic range and contains links to free online videos that explain some of the complex techniques and concepts in greater detail.
“Pushing Light is a 112-page discussion about the tools available to photographers to manipulate the most basic building materials of a photograph: light.”
