Photoshop on Models

Video 1
In the video I watched, there were quite a few changes made to the model. For one, her neck was made taller. Also, the model's eyes were made considerably bigger and enhanced to look more blue. Her hair was touched up a bit, and her shoulder blades were made smaller, so the neck would look delicate.

The butt, first of all was made smaller, as well as the legs. Her body was shrunk, and the breasts are enlarged. The model's hair was made bigger and longer, and her face was smaller. The skin tone was also altered a bit.

Answered Questions
It is not ethically moral to change people's appearances. It's only making their self images worse, so they'll try harder to be beautiful. I think every circumstance is wrong to do that. Not anything could change that. Only maybe in nature could a little twinging not hurt it too much. Fashion photography is only focusing on one specific subject. Photojournalism can focus on a wide range of subject, including fashion. Fashion is making reality standards high, and therefore almost impossible to reach, making people feel bad about themselves. Photojournalism can be a wider subject range and doesn't involve too much photoshop, not affecting the reality too much.
My teacher probably made me do this since we're doing self portraits and portraits in class. We don't want to photoshop faces too much, otherwise it'll look too fake.
None of the fashion photographers photoshop guys, probably because of the fact that they aren't that self dubious of themselves and already think they look 'good'.
