I am not capable of taking good photographs when I am uptight or can't relax. When I can't relate to people around me (How do you know a conversation is bad? Like when a friend talks to you and you don't have much more than a yes/no answer and then a silence falls. It's different than the silence that falls between friends who know each other well and at the time there's no reason to speak.)
Sure I can take photographs, and with my "professional" attitude, I can even take technically acceptable ones. But, unless I am able to get past the haze of "unconsciousness" - for at that time I am not "myself" and I am not acting "consciously" (Different than the beautiful "unconsciousness" when things really click without thinking - this is an "off" state), the photograph will be missing something essential, that I demand. It will have no spark or soul.
At times like these, I am an automaton. The world around me is a blur. I can navigate the intersections and obey traffic signals but I am unable to really "see" - At times like these I cannot take good pictures.
