Ah! The proposal! 

If you are thinking about having your proposal documented, think no more. Take my advice.. do it. 

There's nothing sweeter than asking your love to be yours forever and then having me pop out of the bushes to let them know I captured it all! Okay, maybe I won't pop out of the bushes that obnoxiously but I'll capture it discreetly. They won't know I'm there. We'll work out a scheme to be sure it all goes smoothly and in the end you'll have that amazing moment they said "Yes!" captured in time. How awesome is that? They won't believe you were thoughtful enough to think of it.
