I think it is safe to say that most wedding couples prefer to have mixture of formal and informal (reportage, documentry style) photographs to remember their day by. It's your day so you call the shots (no pun intended), posed family and friends, bridesmaids and usher portraits can punctuate lots of atmospheric photos capturing the moment and day (black and white prints too).
Printing to canvas is a service I also provide and is proving to be growing in popularity, if you like the idea of creating wall art from one or more of your wedding photographs you can choose from sizes as small as 12"x12" up to 36"x48".
