When the artist photographs himself, there is a dichotomy of interests. As the photographer, you want to create a favorable impression of yourself. In regards to your portfolio, you want to create a truthful image of your self as a photographer. In this situation, the photographer has to remain true to his artistic principles and not vary them to meet personal wishes. Artistic integrity is tested to the fullest, but any alteration in that integrity can lead to a breakdown in the believability not only of that one photograph but of the entire body of the artist's work.
The photographer must realize that a portfolio should resemble a unified body of work. That work reflects the artist's criteria and skills; so, in a sense, all of the work reflects the grand vision of the photographer. Basically, however, the photographer does not let personal feelings interfere with an objective interpretation of th quality and selection of images for the portfolio. The portfolio allows the photographer to explore and convey thier own individuality in a neutral way.
