I use iPhone to take pics almost everyday. But now I shoot videos via iPhone almost as often as I take pics. Since there're more and more gears that make mobile video shooting more convenient, and more apps for post-production, it seems that the popularity of videos are overwhelming that of images. Under what circumstances are you more inclined to shoot vides rather than taking photos? And when will you choose taking photos rather than shooting videos? What's the biggest differences between your experiences of the two??
