How Many Photographer Actually Know Photography?

Today one of my student finally follow my advice... he take his 600ws battery pack to do some real outdoor flash model photography. As his result, he comment... he feel he can't well control the fake HSS flash with ambient light... he agree this due to not enough exercise... and one serious misunderstanding in his brain is today's fake HSS shots without banding line in the frame is due to he using a wide angle lens(that is actually not related). That's ok and acceptable if he is a just a hobbyist, but he is a senior photography tutor... who teaching in 3 photography school to certificate senior photographers at China... and he making good money then me ;)
