Avoid "portrait photographer" they often don't understand the need of the fashion industry. See the photographer's portfolio. Do you like it? Does it represent the style and format your looking for? Commercial photographers might be a good source of work! Keep that in mind. Be concerned about photographers who seek to take nude pictures of you or claims to be working on a swimsuit calendar. Photographers should be professional and respectful and you should bring a friend along. Always be cheerful, you never know when you might get a free shoot or a free picture or an extra roll done at no extra cost! If you bring your own clothes to the shoot, always bring extra. If the photographer for example like your look and decides to do an extra roll you will be ready to benefit from it. Keep an open mind photographers loves to do editorial shots.
