You don’t have to worry about a film crew taking over and spoiling the day for you and your guests. I'm a solo shooter and I keep a low profile during the day, in fact, many of my couples forget I'm even there!
I'm sensitive to what you want and need and will take my cue from getting to know you—so if you hate posing or standing about for hours with a fixed smile, that's fine. Equally, if you prefer to take some time out for special moments, that's good with me too.
