I noticed this man as he sat in a coffee shop and watched as he wandered in his thoughts. I reluctantly interrupted to ask permission to take his photo.  After asking me why I told him I had a project going where I try to take at least one photo a day. My answer was sufficient as he agreed to let me take his image, wanting to know what to do.  I suggested he just relax and be himself. I think he did that very well and think I captured him in his thoughts. Not sure where he was in those thoughts but that is not the essence of the image. He let the camera create the image. Now is this a candid portrait?
