My wife and I have been talking lately about her starting her own photography business on the side. She does not know a lot about the equipment, but she is very good at setting up protraits and is often requested by friends and family. I am trying to research how much start-up costs would be and right now all she has is a Canon rebel XT. Obviously, this is not the best camera, but is it adequate to start, or would we have to invest in something better. I figure we would need a backdrop/stand, but what about lighting? We had a photographer come to our house that had two remote strobes. Is this something that is a necessity? Any advice would be appreciated.
