Photo Manipulation and Ethics

The story is about photographers who altered their photos. All of the photographers who altered their photos were fired and lost all their credibility. And the National Press Photographers Association said that manipulation is unethical. I think there unethical because they aren't telling the truth and they are the press they should be unbiased about their stories.  

These are the unaltered photos

This the most unetical because they change it to look more news worthy and it looks worse than the other two.

This the least unethical because they just made the pyramids closer so they can fit on the cover
