However, as a digital artist, I don't find fault in the fashion and beauty industry for retouching. They are creating a fantasy. Fashion, as a whole, is a form of art. The problem is when the public can't separate the fantasy from reality. We need to approach these images as art. We shouldn't think they are reality.
A lot goes into an image. Makeup, in itself, is a form of retouching. Then, as a photographer, I can tell you that lighting will play up or play down features, as does lens choice. Retouching is just the final polish on the image.
My approach to retouching portraits and headshot is to remove non-permanent marks (pimples, scratches, buses, etc.). If the client would like the retouching to go further, I will do so per the client's request. Typically, headshot do not go any further than removing the non-permanent.
When it comes to my digital art, I want my subjects to look like paintings. Therefore, I approach the retouching as creating art and making the subject look like a painting.
As you can see, each genre of image has specific needs. So, the next time you see a gorgeous image in a glossy magazine, remember that it is art and love yourself for everything that you are.
