I love engagement photos but originally didn’t want them because the cost of wedding-related photography really bothers me, and I thought my money could be better spent somewhere else. But my FI thinks they’re a great idea, so we’re going to get some done once it’s not so cold and gross outside. ;P We’re going to use them on our wedding website, and also just keep them for sentimental reasons; we’re not the type of people to take a lot of photos of ourselves so we have a surprising lack of “couple photos”.
We will probably pick the same person to do our wedding photos and the engagement photos, it’s a friend of a friend who’s done destination weddings before, and we’ve even seen her in action so it’ll work out pretty well I think.
But by all means, if they’re not important to you, don’t do them! It’s your wedding and your budget, do what’s right for you.
