Just as it is important to consider who you work with, it is also important to take every aspect of your reputation seriously. Every time you work with someone, you are building onto your reputation. The impression you leave those you work with can have a potentially significant impact on your career. You will typically get much farther and progress much faster if you have a reputation that works for you, rather than have one that may be questionable.
Don’t be flaky. If you schedule a shoot with a photographer, don’t cancel at the last minute. Last minute cancellations are often done at great expense to the photographer who gave up valuable time to schedule working with you. When you cancel unexpectedly, it means that regardless of whether the photographer was paying you or getting paid, productivity is lost and that time is wasted. Photographers will often not work with a model again if she cancels a shoot without sufficient notice.
