In planning a wedding with my partner across the ocean I have come across a huge variety of wedding blogs, catering to different styles and niches of wedding. Most of my favourites display gorgeous images of wonderfully diverse people and all their different wedding celebrations:
Offbeat Bride has been my favourite though, because they have a private 'no drama' ning site for all sorts of offbeat brides (and grooms) in fully-fledged wedding planning mode. While Mr and are decidedly 'offbeat lite' we are also a transatlantic couple, and there's a group on the ning site specifically devoted to us 'geographically challenged' couples and that has been a great resource and constant source of support.
Many of these blogs show couples who opt to have engagement photo shoots to announce their wedding, and to get the opportunity to practice in front of a camera before the big day so they don't end up looking back on awkward family photos in years to come. We didn't do this (it's not wholly practical when we have limited time together and spend most of our spare money on flights) but we are in the habit of capturing the few precious moments we get with each other. When we were on our recent trip over to NY and PA, my mum half-joked that we needed plenty of photos to show immigration one day and gleefully snapped us at every chance throughout the trip. But indeed, photos of our relationship across time can form part of the requirement to provide immigration with "Evidence of a Bonafide Marriage - relevant documentation to establish that there is an ongoing marital union".
