I've long held the belief that the best thing one can do to improve their pictures is study the work of other photographers.
Sitting on my desk is a book by the Texas photographer, O. Rufus Lovett,
Weeping Mary. It is one of those books well worth spending hours looking at and going back to. Lovett has continued the tradition of Walker Evans by by opening to us the heart and souls of the community of Weeping Mary. You don't need to go to faraway places to take great photographs. If you have the heart and eye of a Rufus Lovett, they are just down the road.
Get it, study it, read the interview in the back on Lovett's development as a photographer and you may even weep a little when looking at it.
