As a photographer, I love Photoshop because it lets me tweak things like brightening a dark picture or removing a blemish or two, but there is such a thing as too much editing. I truly do not believe in over editing because it is super unrealistic!
Why even bother with models if we can digitally create them with a few clicks of the mouse? The image that the media wants us to strive for is unrealistic. The media wants it this way so that we buy their products that promise these unachievable changes. Does seeing the before and after make you feel better about what you see in the media?
