Feet are really valuable when it comes to taking photos as it is a great base and the positions that allow photos to be taken in perspective. Feet allow the body to squat or lunge to the sides or look forward and back, once again, giving more perspectives. There were times where limits were put, as I couldn´t reach spots no matter what positions i was in. Even if i was walking to a higher positions or farther or closer, so what I would do is wait a little bit, think about what I could do, even if i was in a ridiculous positions for the shots. You just have to deal with it and eventually time the shot right.
