It sounds like your photog is staying at a different resort? If so, (based on my recent experience) you'll definitly have to pay for him, and the fee is currently $350 (or was 2 weeks ago!).
In my case, I told my offsite coordinator my plans to use outside photography as I was making all the arrangements through her - a couple months out - when I provided numbers, meals, and other extras I wanted like dance floor. She then sent me a whole recap with all the fees I owed, broken down by each piece, which I paid before I was assigned my onsite coordinator (about a month out). I got a balance sheet back that showed everything paid, and my onsite had it when I arrived. She noted the outside photog with the front desk, and they had no issues getting into the resort to shoot from there!
Does that help?
