1.)  The models face were shifted down, her neck was raised, her head was made a little bigger, and her eyebrows were raise.

2.) Ethically yes because its a commercial and the model new they were doing it but from my personal opinion i don't think they should've changed her face and neck around.

3.) Yes there are circumstances  in which it would be more ethically acceptable to manipulate the photo as they did.

4.) If you ask me no changes really are acceptable unless your just fixing the background or the photo it self, not the actual model.

5.) Fashion photography is pretty much modeling and self portraits mainly. photojournalism is taking any and ever type of photo you can.

6.) Each type of photography shows what happens when no one i spaying attention. it sort of gives a reality check ti certain people about some of the issues that are captured. This affects the ethical practice  of each type of photography because just like that video photography can capture what people really do to make models look the way they do.
