It indeed has to do with burning and fire, Marcio, and I am glad that you say that. The fires of the iron cast company in the night are always comforting to me, since it is the same good old workers, the same kind of hard working guys that I always wanted to be a part of.
It is such sights and such guys I find most human and most interesting of all. The view and smell of human activity, streets, trains, work, just ordinary people, is for me endlessly more beautiful than any hollywoodian wannabe-macro of some flower in a pubertal silly "poetry album". That's for losers who let somebody else work for them while they advance in the romantic self-admiration, ey? ;-) To hell with the latter, I am in life and so I try to photograph life, real life, most of the time.
