Relax, she’ll be right.
I shoot my sister’s wedding a few years back with a 400d 18-55mm kit lens, Sigma 70-200mm f2.8 and a flash. The photos turned out great, the weather definitely helped Melbourne in summer. I just floated around taking picture nice and relaxed, at the reception I mostly kept my distance using the 70-200.
It’s not all about your gear, a great photograph with a crappy old camera will take better photos than a **** photograph with a 1d and a bag full of L glass.
But after saying all that I wish I had my 1diii and 50mm f1.4 back then !
Just make sure you get the kiss at the ceremony !
