See the above? There is no way I would look like that in real life. I wish I would be half as Perfect but I am not.
So why do people put filters on their photo? Honestly it is because it adds a great deal of improvement. Not that there is anything wrong with posting unedited or raw photos. But people will agree that when you post a Photo that looks this good it makes you feel proud and happy, knowing that if there was a way to make certain changes they could/would look perfect.
This world is far from perfect, so people should not be ashamed of their imperfection right? Well, there is no simple way to answer that question. I believe the allure behind a perfect photo is because of the fact that it shines amidst this Imperfect world.
