All hail the king.
Mine lasted 2 hours. I brought two changes of clothing: A casual outfit (the shirt I'm wearing in my piratey picture found in the "What do you look like?" thread and a pink and black, strapless dress. Additionally, there were cap and gown shots and drape shots.
I recently found out my photographer was a pervert. He kept telling my friend to straddle things in a suggestive voice, talking about how pretty two other girls were, and told her to pretend it was like a porn shoot. Fortunately, my mom came with me, so he did no such things. However, he did take some black and white pictures of me laying on a blanket with rose petals all around me--all but one were "lost"... My mom believes he kept them for himself.
That one black and white picture that we did receive looks great though along with most of the other pictures.
The two hours were completely worth my time, but I'm a girl, and these things seem to matter more to us than most guys. *shrug*
