Firstly, I apologise for the promotion. I've just finished an interview with a friend of mine who has recently begun wedding photography and recently completed his second wedding.
We decided to do a 'basics' video because his advice is simple and aimed at beginners because he is a beginner himself (though he's been an amateur photographer for 15 years). People who have done it for years forget those little things that become second nature. I thought someone might find it useful or interesting.
