How many weddings have they shot before?
Are they professional or do they do this just for fun?
Important to know their style and see if it matches yours.
Discuss what you envision for your day.
Is the photographer someone you get along with?
Although the last thing you want to do is shop by price, is this person within your budget? If not is she or he worth the price difference.
How long does it take to get the proofs back?
Can they provide them?
ALWAYS ask if they have back up cameras. This is very important as the last thing you want is the camera to break and they don’t have another one, this also goes for all equipment.
Again this is very important ask. Has the photographer ever worked in this location before? A local will know the area and will have a better knowledge of all the great locations.
