Self Portrait vs. The selfie

1. What is a selfie?
2. What is a self portrait?
3. Is there a difference? If so, what?
4. What style do you prefer?
5. Is one more valuable/important than the other? Why?

The selfie is a picture taken by yourself and you are the main focus of the picture unless you have a group along in the picture. A self portrait is a picture of you but taken by someone else. The difference between both of them is who takes the photo. I don't prefer either one it depends on what camera i have, but self portrait looks better because typically for self portraits use a better quality camera. I believe self portrait is the most valuable/important because it looks more professional and can come out better quality.
