I have stumbled across an opportunity to build my portfolio by photographing a local singer/songwriter. I'm intending to shoot using natural light in an outdoor location. I have several simple locations in mind, plain brick walls, stairways, interesting architectural backgrounds and stuff like that. I just wondered if anyone had any advice that will help me look as professional as possible. I will be taking two cameras, a Pentax SLR and a Mamiya TLR plus my tripod light meter and plenty of film. Thanks for any advice you can give.
