Discuss with the photography some his abilities at special effects if you really want some different shots. Special effects from infrared film, fish eye lenses or specific outcomes like sepia toned prints and handmade wedding albums are not run of the mill for some photographers so it is important that you examples of the photographer’s technique for the special effects you have your heart set on.
If the photographer is not comfortable with the different techniques or effects you absolutely have to have, then this is probably not the best one for you because you do not want him to learn off your prints or use them as guinea pigs for experimenting in his darkroom. When you provides you examples of his work, make sure they are not too overdone or artsy because these are still wedding photographs or that the look is not barely noticeable because you want to see the special effects.
