It's always really important that you get a great vibe from your photographer and love their work before committing to them. Any opening questions you ask a photographer should be met with a warm welcome and a clear indication, such as what's included within your package and what you'll pay in terms of deposit. You should talk to your supplier about their style and the type of shots you want for your wedding. They should also have public liability insurance, so if you're not sure, then ask. Find out what they cover in the event of a cancellation or emergency. Your photographer should agree to re-schedule at no extra cost. Ask to see examples of their work if you feel you haven't seen enough. They should be more than happy to provide you with this. It's always good to try and get to know as much as possible about your chosen supplier. The most important thing is that you feel comfortable and relaxed. They are, after all, capturing one of your most special days.
