Taking the photo should work just fine, I just tested it again. What may be a bit misleading is there are actually two photospots in the scene. One of those (the more obvious one) won't work on purpose, since it's too far away for a close-up shot. Just keep searching for the second one (try the rocky part near the exit to the path up the cliffs). I'm going to add some kind of a hint to make this more obvious.
Hope that helps. :3 If that still doesn't work, I can help you better if you clarify the problem a bit further.
