when one is miserable (i have LoTs of experience in this emotion), our thoughts and emotions are affected. it changes the way one thinks, reacts to something, even though normally we would react a different way.
i used to photograph a LoT of homeless people, mainly because i have lived on the streets myself; as a teen and now as an adult. while i am not proud of it, there is a change in oneself when you live on the street.
you either decide to be more harder (cold, distant, unfriendly) or more compassionate (more helpful, more kinder to others, especially those in need). strangely enough, i changed for the latter (friendlier, though i have always been too DAM friendly).
i dont shoot too many homeless now; it depresses me. instead, i like to capture scenes of solitude: lone trees, empty and single benches or chairs; singular objects and scenes always attract my eye now.
but from our misery, the world is able to see the misery, and sometimes the beauty that hides within us.....
