In Baton Rouge: John Power,

RL names used because this is a reply to a request for a business referral and these are the owners/operators of the businesses and
ARE NOT known to be involved in the hobby in any way.
I have met and seen the work of both of these photographers and believe it to be of fine quality. Noel has actually progressed to teaching photography workshops.
I am a hobby photographer myself, but prefer not to get too involved in it as a business.
