It doesn’t matter if you have an outdoor or indoor wedding, you need to prepare for rain.
You can’t control it, therefore don’t stress about it.
Always have a back up plan, and delegate someone to bring along some big umbrellas. I’ll have at least two – one for you and one for me.
I have shot a wedding on a clear and bright summer’s day only to have the rain come through a summer storm. It was an outdoor wedding, so we all had to flee to shelter. Some of my favourite photos were taken at that wedding.
In short, surprises produce surprising photos.
