Perhaps you are hiring an amateur photographer, roping in a friend to do your photos for you, or you just want to look over the possibilities before you get to the studio.  Whatever your situation, here are some suggestions for when you take your engagement pictures.  Mostly I've suggested different poses I've seen done, but there are a few techniques I mention, too.  The more variety you have in the pictures you send me, the more inspired I'll get in creating your unique invitation.  

1. Try laughing together
2. The girl can snuggle into his shoulder
3. Catch him gazing at her while she's looking at flowers
4. The piggyback shot is what I used in my own wedding invitations
5. Capture a stolen kiss--on the cheek, the forehead, or the traditional--just make sure eyes are closed blissfully
6. A bridge makes for wonderful scenery--try looking into the river, almost as if you're pondering its symbolisms for your life ahead
7. Sit back to back and turn your heads toward the camera or towards each other
8. Look off into the distance together
