You need to hire a photographer who has experience in shooting weddings and whose work you like. A street-style photographer may be able to capture some great shots but if he hasn’t shot a wedding before, you risk the chance of him missing some key moments since he doesn’t have the experience to know what to look for and when. And a photo shot list will only help so much.
Why not look for a photographer who can do both, and not someone who just says they can do both but who has shot weddings and you can see a complete wedding album to know for sure that you’re getting what you’re paying for.
You don’t get a do over on your wedding day so don’t risk missing the moments you want photographed.
