More on the Ries Tripod and how to use it--from an article I wrote quite some time ago:
On Using a Ries Tripod
Michael A. Smith
I bought my first Ries Tripod in 1977 with money from a National Endowment for the Arts Grant. I had seen a photograph of Edward Weston using one and I suspected it was probably the best. My suspicions were not wrong. It was one of the best equipment purchases I have ever made.
Here are a few things I discovered along the way about using the Ries Tripod. The Ries is a hardwood tripod. It never jams when used in sandy locationssand dunes or beachesas do metal tripods when sand gets on the legs and keeps the sections from easily sliding. It is never uncomfortable to handle in either hot or cold weather.
The extendable legs can be used with rubber tips or with the spikes at the other end. When using the tripod outdoors always use the spikesno exceptionseven on concrete surfaces. They will not slip. And the spikes insure that there will be no vibration. After making thousands of large-format negatives, I have never had the tripod vibrate once. Indoors, I use the rubber tips. If you are doing mostly indoor photographing such as still lifes, another tripod, a Majestic for instance, might be preferable. In the landscape, however, there is no other tripod that begins to compare with a Ries.
If you are reading this, I am sure that you already know to have the front leg facing the subject or scene you are photographing. This is so you can stand between the two back legs and are therefore less likely to kick the tripod. When setting up a Ries tripod, always, without exception, extend the front leg about two inches longer than the back legs. With metal and carbon fiber tripods it is usually necessary to have all of the legs extended the same distance, but never with the Ries. This is because, when setting up the Ries with a camera on it, one can easily balance it on that front leg and then pivot around that point. Also, when collapsing the camera and tripod, one grabs the back two legs and balances the camera and tripod on that front pivot point. With the back legs shorter than the front leg, while maneuvering they never touch the ground and get hung up on rocks or plants or other uneven terrain. You then collapse the back legs together (the camera is still on the tripod), push them forward toward the front leg (all is now standing on that one pivot point), bend your knees, and the tripod and camera will incline gently onto your shoulder. Just lean into it and straighten up to walk. The tripod and camera, as heavy as it might be (and my Deardorff 12x20 with the 8x20 back weights 35 pounds without a lens) never has to be lifted. No extra strength is needed to set everything onto your shoulder to walk to the next spot. The dark cloth remains attached to the camera as well so that I can bunch it onto my shoulder as I am doing this so that it becomes a convenient pad for bearing the weight of the camera and tripod.
I had never realized setting up a tripod was anything that needed explaining, but when the photographer Paula Chamlee and I first got married we were photographing at Canyon de Chelly and I saw Paula working at the very edge of an 800-foot cliff. She was struggling a bit with setting up and taking down her 8x10 camera and this was her first experience with a Ries tripod. I was afraid she would fall off, so I felt compelled to say something. After I explained about the front leg extending longer and its pivoting advantage she has never again struggled with setting up or carrying the camera and tripod. To this day she carries her 8x10 camera as easily (almost) as if it were a 35mm camera.
The other important tip about using the Ries is this: never (except when working indoors on a smooth surface) lock the legs. Never. When I used the Ries for the first time I dutifully locked the legs. I needed to level the horizon and could not do so. I became so frustrated that I was ready to throw the tripod in the swamp where I had set up. And then I unlocked the legs. Voila! To level the tripod all one has to do is gently move one of the back legs toward or away from you. It takes less than a second to do this. Now, this was with the older Ries tripod head, one without the side tilt. Paula and I have the tripod heads with the side tilt, but prefer not to use them. With a relatively heavy camera (an 8x10 or larger), when loosening that side tilt lever you have to carefully hold the camera so that it doesnt suddenly flop all the way over. It is so much easier to just nudge one of the back legs. And we both do this quickly without coming out from under the dark clothit takes only one hand and a nudge with the knee to quickly get the angle one wants.
The versatility of the Ries tripod is unmatched. The unlocked legs operate like a hip joint and rotate in many directions, not just the two directions of in and out. Therefore, you can align the camera to virtually any difficult position or angle. If there is, say, a cliff alongside of you, you can easily extend one leg almost horizontally to secure into the tiniest crack in the cliff. When you are on uneven terrain, each leg of the Ries can be a different angle, yet the head remains perfectly level for stability and aligned viewing. The legs never need to be locked unless you are working indoors on smooth flooring.
For maximum versatility, and if your budget can afford it, I recommend getting a set of extension legs and a short tripod. Extension legs allow you to elevate the tripod quite high (you will need a ladder to be able to see the ground glass) and it also allows something else: Once I was photographing looking down a stream and the back legs were balanced on rocks, but there was nowhere to put the front leg, as there was a steep drop-off into a pool of water. On the other side of the pool, however, were more rocks. I connected all three sets of extension legs and attached this assemblage to the front leg. It extended about twelve feet, long enough to get over the pool of water. Without the extension legs, I could not have set up the tripod for this particular situation.
Another example: I was photographing in a city and wanted to photograph from a bridge. There was a shoulder on the road with a concrete barrier at the edge, but if I set up the tripod as I normally did I would have been dangerously close to the traffic behind me. So I set up my short tripod and put the extension legs on the back legs and set the short front leg almost upright on top of the concrete barrier of the shoulder. The back legs then were much closer to the barrier and I could stand on the shoulder without worrying about being in the traffic lane.
My opinion is that the Ries is such a great tripod in the landscape when used with a large-format camera that anyone who uses a different one is making life much more difficult for themselves, and not having the ease and fun that should accompany their work experience.
