PSA Photojournalism Definition

Photojournalism shall consist of pictures or sequences with informative content and emotional impact, including human interest, documentary, and spot news. The journalistic value of the photograph shall be considered over pictorial quality. In the interest of credibility, photographs which misrepresent the truth, such as manipulation to alter the subject matter by adding or removing portions of the image, or situations which are set up for the purpose of photography like hired models, are unacceptable. The only editing that can be done includes cropping and color correction that could be done in a darkroom.  
There are two classification that you may list a photo journalistic image under, General and Human Interest.
Human Interest must include one or more persons (not implied, actual persons).  Sports action cannot be the main subject of the image (that would be considered “sports photography”). You may have person(s) in sports gear, but not actual sports action. Additionally, the images must show some type of interaction, emotion or unusual situation and the subject matter cannot be staged.
General classification can be almost anything, including Human Interest, but usually it involves non-human related events (man made or natural disasters are a good example).
