Is Photoshop really necessary?

 Since the discovery of Internet, a lot of programs have been used in the fashion industry to retouch models photographs with the objective of making them look absolutely perfect. From my point of view, I support the natural beauty of every woman and I think that nobody should feel ashamed of himself. However, I do not see Photoshop as an enemy. I think that it can be a very useful tool if people use it correctly, everything in excess is bad in life. Maybe, if we want to retouch the lighting or even any spot o redness on the skin, we can use Photoshop with no problem. The real problem comes when the physical appearance changes completely, to the inability to recognize her or him. Recently, a famous Spanish actress complained on social media about one photo of her, made in a photoshoot, where she compares the retouched photo with the real one. There, we can see the big difference between that "perfect" girl and the real and natural girl. Definetely, I believe that sometimes Photoshop can give us really amazing works, but we must be careful and use it in a good measure, not to make big mistakes which make us create a totally different person.
