When you have a mirror, use it!
Those Mirrors make the prettiest pictures and usually they are candid shots!
I aim for those candid shots so I scope out a mirror EVERY. SINGLE. TIME!
It usually involves them putting on the vail, earrings, a necklace, looking at their dress, etc and makes the most elegant pictures.
Those shots may not be something they will blow up and frame but they will most definitely put them in a photo album/book and show their children and their grandchildren for years and years.
