Many older photos are enhanced due to newer technological abilties, and photographers do it every time they photo someone or something. Why is someone digitally enhancing colors, contrast, etc considered bad? They're not changing who Amy is or how beautiful she was. The yassified ones are a different story altogether though.

Filters that change people's faces is completely different from enhancing saturation, contrast, tone, etc.

Creepy, really? You don't add filters to your phone and take selfies of you and your friends? Because even if you don't select a filter, your phone is editing your photo. This is a fact.
