I asked if he was a professional photographer, and he said he was. He then explained that was the reason why he was "biased" (against living in the moment).
I thought this all a bit sad. As the light faded and the photographer left in his Mercedes, I thought that maybe his quest was indeed noble: To show this light again. But how sad this is, to settle for a small photograph in a frame when we could have taken the time to really experience the real sunset.
I was thinking before he took the pictures, that it could be the one of the last amazing sunsets around he for a while. Considering this I thought it better just to sit there and look.
