How do you say, 'will you please take our picture' in italiano?

We thought that we would post some pictures of us together, since you don't often get to take pictures together when travelling as two. We braved asking strangers on these occassions. The first picture catches us trying to tell the gentleman that you 'just have to hold the button down a little longer', woops! The second is from last night on Piazza Navona.
