Photos are obviously in order, but we’ve found an incredible addition for couples with plenty of room in their budgets. Artist Anne Watkins, 212-866-0057, annewatkins.com, creates a series of unposed watercolor paintings "live" at events, while sitting inconspicuously in a pew during the ceremony or at a table at the reception. The results are glorious, fleeting moments captured in a graceful, abstract way. Couples receive up to 12 paintings, created on high-quality hot-press paper from France and packaged in an archival box. She can also create thank-you cards using one of the watercolors. Cost: $10,000 and up for at least 12 11"x15" or 7.5"x 11" paintings; reproduced thank-yous are $8 each.
