I think it's low self esteem to engage in any act that would make someone appear better in pictures. For you not to use it for your business purposes, it means you are not using it as an agent of deception. That's very good. Filter should be just a little finishing to a pictures. However, if you see what some people do, you would be surprised. A totally different appearance off phone.
Thank you for your nice comment, people are different with the way the accept things. The world is changing.
