When I'm photographing, I don't ask myself questions, that would take all the fun out of it. I just wait until I feel the urge to press the shutter button and then I start making shots until I feel I've covered everything there is in the scene. I watched one video for a short while and decided quickly enough that David du Chemin's approach is not my cup of tea.
Wait, that's why I'm not a great photographer! Oh well, life's too short to do things you don't really like.
