If its just to take pics, why an enclosure?
Are you scared of the neighborhood kids that you cant whack em with a broom if they get too close? Are your bushes full of deadly predators that cant be kicked in their ribs for going after your snakey? If not, why bother with the enclosure. You should be all the protection he's going to need IMO, especially if its just for photo shoots or to cruise the grass.
