A good wedding photographer can literally make life-long memories with your family and friends and make you relive those moments every time you see your photos and videos. These are possible only when couples ask a few questions to the photographer to get things right. This casual yet professional interview is necessary not only for great shots at the end but also for being comfortable with each other.
Here is a handy list.

In what style do you shoot weddings?
In other terms, you want to know his method of capturing the moments. For example, is he/she a big believer in candid moments or want you to strike a pose for every shot. Other styles could be cinematic/documentary, stylized or artistic, etc. This is important to match the theme you have decided on.

Could you show some of your past wedding works?
This is an insight into the photographer’s portfolio as a principal shooter and not the number of years of experience. It becomes crucial for you to know he/she has a sense of the right and important moments to be captured.

What are your deliverables?
One of the most important questions to ask is how many photos you will get and in what form. Are there any other things included in the package, like an album or non-edited photos? Making things clear of what you will be getting in return for your fees is necessary.
What are the total fees and the process?
The process might include a form to fill or an e-mail to shoot, depending on their approach. Also, make yourself clear if the fees also include an advance deposit to seal the deal.
When will I receive my deliverables?
This will help you to get an idea of the time frame before you have your photos in your hand. Knowing beforehand will be helpful to manage some butterflies in the stomach.
