"To me, photography should be about feelings.. revealing either about the photographer or the object , or even both.. it should be about capturing and freezing the moment, the emotion, the soul, in that specific time down to the milli-second, thru the interpretation of lights fall upon the object.. therefore, photographs should not only be taken with quick sharp eyes, but also, more importantly, they should be taken with heart.. "
- Tommy A. Siahaan
