I am -so to speak- a 'people person'. I try to make good use of it when making portraits for various clients as many times the contact is brief, but intense.
For my free work I very much like to visit small to medium fairs/exhibitions to enjoy the odd and/or unique moments that pass by to never be seen again.
I have found that such events almost look and feel as a sort of play where nobody seems to be aware of but plays their part.
