The basic concept of mobile journalism or video journalism is that journalists today can pretty much work as a one-man-band simply by using a modern smartphone with an excellent camera - iPhones seem to dominate because of the quality of the camera and all the varied accessories available for them.
I am a photographer, sketcher, and watercolor painter. I offer training on learning how to use your camera more efficiently as well as on sketching and watercolor painting. In addition, I sell originals and prints of my watercolor paintings.
