Photo Manipulation and Ethics

A. It is left to readers to decide the limits to photo-editing and what is ethical or unethical. The media plays an important role in influencing what an audience believes using their photos, so if these photos are altered, is it fair to to an audience to make judgements this way? Another question arises from this: due to those who post online such as bloggers, what is considered media?
B. The philosophy of the New York Times and Washington Post is that an audience has the right to make judgements based on the truth. If a photo is altered, than it is no longer an original, valid image of the event.
C. It is ethical to alter a photo to portray the event more accurately. For example, if the photo was underexposed, then you could rightfully edit the tone of the photo to restore it.
