I probably am being VU but every time I see a picture of somebody with their arm stretched out obviously holding a camera/phone, or worse, taken in front of a full length mirror holding a camera, I can't help but think they look horribly contrived!
I mean ones specifically put up on places like Facebook to generate comments like "u look stunnin" rather than (for example) pics to record a growing bump in pregnancy ... Though I think I'd still ask someone else to take the pic for me!
