Planning your wedding takes serious skill. It comes naturally for some and not so naturally for others. When it comes to booking your photographer there are just a couple of things you need to already have planned and executed. At the top of your wedding planning list (and I think the MOST important) you have the man. Check ✔. The wedding date will need to be nailed down. so you can check off the next thing. You have your dream venue. Check ✔. The next thing you will want to book is your dream photographer. When you book majority of professional photographers will save a deposit on your wedding date but the price may very based off location! So make sure you have your wedding venue booked before sending off the inquiry with your dream photographer.
Most photographers book 1 year in advance. So if you find the photographer that is the right fit for you in both personality and photographic style you better message that photographer quick before someone else gets your day!
It is really that easy just those three things will need to be completed before reaching out to your photographer. Popular months that book up fast are July - September. You can wait longer, but that just leaves to chance that another bride might books with them.
I hope this helps make a small piece of your wedding planning easier!
