@prncevegeta is right. If you look at the quality of photo Meg herself posted as the preview on OF, you can tell the quality was shit to begin with. Could have been lighting conditions, but I personally think she was taking the photos from wherever she could prop up the phone. That was probably on other side of room and required it to be zoomed in. Only explanation I can think of for quality like that these days. Phone picture quality drops horrendously when zooming in.
Posting lower quality like that allows her to be a bit more daring, less to see as it were. I'm all for it. I actually prefer her candid photo sets than the professional ones.
while i agree she's more daring with the candid vs the professional ones o don't think she purposely trying to make them a lower res for "less to see" I think she just used her front facing camera so she could see her poses as she went. At least thats what it looks like to me.
