RE: Camera setups
Same tree, above hunter is VERY important. Commnunication is critical between the hunter and cameraman. Without it - you're asking for trouble. Several of our teams had the cameraman below the hunter this past season - and it results in poor footage because of the angle (bright sky behind hunter makes hunter very difficult to see).
We have set-up in different trees before, just because of tree size, or issues with getting two stands in a single tree. Sometimes it can work, but it is not the desired set-up. Worst case you can always set the cameramans stand directly above the hunter (about 8 feet above). In certain circumstances, you just have to make it work as trees are never easy to set-up. Every set-up is different, but generally you try to get the cameraman's stand about 4 ft. above the hunters stand, on the opposite side of the tree.
