Photo Manipulation and Ethics

A. Some of the main points I saw on the website about manipulating images: it is unethical to alter images, the genuineness of a photo is affected by changes, and one must be careful in the present when looking at photos because most if not all have been edited in some way to appeal to its audience.
B. Newspapers like the New York Times and the Washington Post have strict guidelines that are meant to keep photos as genuine and original as possible. Photographers must also turn in the original photos in order to get their pictures approved.
C. I think it's acceptable to crop an image to focus on the main subject, and I think it may be alright to change lighting in an image if only for aesthetic purposes, but anything more than that is too much in my eyes. Changing skin color, making a person a more 'desirable' shape, adding people in an event or taking them out, are all too much to me.

I believe this image is the most unethical because of the major changes made to Oprah and the lack of permission. The newspaper took Oprah's head and pasted it onto Ann-Margret's body, without asking either of the people involved. The issue is how they have tried to make Oprah's body so different from her true one, how they have changed Ann-Margret's skin color to match Oprah's, and how they have given the impression that Oprah is attempting to appeal the public with her appearance. This goes completely over the line.

I think this picture is the least unethical because they didn't do much more than change her teeth to make her look a little nicer. Her teeth do not draw attention in the new photo, but they do improve her appearance, though I already personally think she looks quite pleasant. It is a small change, and it is not a drastic change that most would even notice. It does not change the truth of the image by much.
