There are many great single shot photographers, no names, but looking at a set it's clear their skills for shooting 120 different images that keep the viewer hooked are lacking. I download sets and then view them in a slide show. And very soon a set gets boring, the same pose over and over again, too many portrait pictures squeezing the image down to 1/3 of my screen and too many shots missing the mark.
Learning to frame a picture, produce a set that flows and keeps members hooked is essential training when it comes to producing videos that keep the member retained and even converting off a tour.
