It's a question that I hear every now and then around the world wide web, and I think all Photographers have a slightly different answer to the question "Should you feed your Wedding Photographer?".
Some Photographers think you're just there to do a job so quit complaining, others think it's almost a crime to not be fed. But here's my opinion - If your Photographer is going to be at your wedding all day, I think you should feed them. More than anything it's appreciative and it's polite.
At quite a few weddings I've worked on, I've sat on a table with guests socialised with them and ate a three course meal. Other times I haven't been put into the seating plan but I'm still given a meal, and so I eat it elsewhere at the venue. At one wedding I was given a little picnic as my lunch, and it was so hot that day that it was perfect! I sat under a tree (I felt like a Hobbit!) in the field right next to the barn where all the guests were eating their dinner, I took off my shoes and I enjoyed my lunch. All of these different scenarios made me more than happy and did not go unappreciated.
Most catering companies or wedding venues will have an option in one form or another for a cheaper meal that you can give to your Photographer (or other vendors you may have hired).
I hope you found this helpful and happy wedding planning!
