Ah, the dreaded catering problem...feeding people at your wedding. I have been there, the invitation list is getting tighter as the budget keeps on stretching and you are avoiding to invite more people because you simply don't want the budget to get out of hand. Then one night you realise that your photographer/s and videographer/s are going to be with you for the whole day and worrying if you should include them in your catering plan.
The decision is up to you. You are not obliged to do so, however think how much better they will perform their job if they are not starving and seeing double halfway through the wedding. Even though it is not expected that you will provide food, if they are going to cover your whole day, it is ultimately within your best interest.
If on the other hand, you simply cannot afford to feel a whole crew of photographers and videographers, I would recommend you speak to them and explain that the budget is limited and you will not be able to provide food. In this way, they will have enough time to plan a packed lunch or some snacks to keep them going throughout the day.
