Presidio - I'll tell ya what - I have a digital camera and it's a pain in the ass to photo a course. You gotta either walk the course without playing -- uh... not gonna happen -- or you have to lug the camera around while you're playing and taking shots while you play (distracting).
Then, you have to face it that many holes just don't work for camera shots on the ground. You have a dogleg or an uphill shot with lots of trees or something, and you can't see the hole. You can take multiple shots, but then it takes awhile to figure them all out when you get back.
Can't recommend enough walking the course from #1 on out and not mixing up holes!
Make sure you have a spare set of batteries (or an extra) or that you've at least just charged it. I took the camera out one time and the batteries died about 1/4 way round the course -- this would be on the opposite side of the world from the car where I could dump the camera.
Make sure you don't go out near dusk (doh!) Courses that are heavily wooded might require a flash as the sunlight doesn't get down through the trees.
Lots to think about, but on the whole, I think it's worth it. Oh, don't forget you have long and short tees too sometimes!
