I think that its unethical to manipulate photos, it defeats the purpose of photography. if you get a picture that isn't that interesting doesn't mean u have to go lie and tell another story or make your own event/ subject. I think photography shows the real side of life by capturing the moment in time to keep, and cherish.
I think this photo is most unethical because it was manipulated to make it look like the solder was forcing the guy to sit down when in the original the guy was holding his hand up and on of his legs we in the air.
I think this photo was the least unethical because the person only fixed her teeth which isn't that bad she need it but its still unethical.
