I had planned to photograph the children before an event and then again after an event (unwrapping of a gift). I thought that I would capture the most significant change in expression that way. However, it turned out that already after a much smaller time had passed ( the time it took for my finger to press the release button on the camera again and again, which was more or less a second ) , the changes were there. Those minute changes are interesting because they can only be registered with a camera. Maybe our brain registers them too, but in general we are not aware of them, when observing only with the naked eye.
It would seem that this is a way to study emotion, flying across the face. It would seem that we can guess what happens internally between one moment and the other. But are they truly emotions belonging to the subject in front of our camera ? Or are we merely projecting our own feelings as viewers?
