One idea could be to purchase him a macro lens for his camera so he can take even better macro photos. Alternatively, you could book a photography class or workshop specifically focused on macro photography to expand his skill set. Another option could be to create a photo book filled with his best macro shots or design a personalized photo album with your favorite macro photos that he has taken throughout the years. Lastly, you could gift him a custom-made macro photography print or canvas to decorate your home.
Or you can get him a star map with the date of your anniversary.
