For horizontal panos, if you’re using a non-video (meaning no leveling bowl) tripod, it’s easy enough to add panning. But you need to add the panning so that horizontal pans are in a level line — so the pan section needs to be (nearly) perfectly level.

There are two ways to approach this. Either a panning clamp (so the pan level is disconnected from the tripod level by the head) on a ball head or pan/tilt — or a leveling bowl below your head if it has panning already built in.

If you are looking to do a lot of panos, or multi-row, there are panoramic heads, but they’re moderately expensive and a bit awkward to use for non-panos — and many/most do not have a built in leveling bowl.

Also: If you have an L-plate on your camera you can flip from landscape to portrait orientation without changing where the camera is pointing. With a video tripod, you absolutely need one to shoot in portrait orientation as the bowl is too wide to allow the camera to be flipped on its side by the head alone. FWIW, I’ve had very good luck with ProMediaGear and RRS L-plates.
