BritM:
I take a selfie either by using reverse camera mode, or by doing it in the mirror like cmd2014 says.
Then I upload my photos to my MacBookPro and edit the heck out of them. I crop them. Zap my zits away. Wipe out my work name tag details, etc. etc. Then I post the photo here.
There is a way to crop photos in my iPhone, but it's just easier to do it all on my laptop.
So, no, my selfies don't look like what I finally upload. My aim isn't that good.
