The shutterbug’s high-style mea culpa tells prospective donors that they, too, have a “unique opportunity to be part of the shoot by sending a personal floral greeting to Kate.” Really? It mustn’t be so! Wait, there’s more: “Simple sprays of freesias are very welcome, and hand-ties of peonies even better, but our advice is to get creative to ensure your contribution stands out and makes it into the final selection!”

Apparently Mr. Knight plans to take pictures of the fragrant offerings before he snaps Ms. Moss. Then, Mr. Knight’s Web site says, he will produce a three-dimensional “photo sculpture around which the supermodel will be posed.”

Donations will not be accepted after December 5, so hurry up and help Ms. Moss be photographed on top of a really neat three-dimensional flower picture!
