Write your husband an e-mail, letter or text explaining Bond Spy School for Hot Dads and then present him with his first challenge:
Your first mission, should you choose to accept it, is to take three pictures of me today without my knowledge whatsoever. This challenge may require covert operation, trickery and/or ninja skills
You might want to indicate how he'll show you the photos, if they are for "your eyes only", and you could give him a time frame (48 hours to complete).
(On a fun note, this actually WAS my first mission which I completed easily. However, I did call on the help of a friend--'cuz girls stick together. Don't be shocked if your husband thinks outside the box.)
