Nodal Ninja SPH-2


Nodal Ninja SPH2

This model (SPH-2) has been discontinued and all warranties have expired. We are no longer able to offer support or replacement parts.



Introduction

Congratulations on your recent purchase and welcome to the exciting world of panoramic photography.
Panoramic photography is one of the fastest growing segments of photo imagery today. With developments in hardware and software this technology allows for seamless stitching of multiple images.
If you take simple two shot panoramic images or complex 100+ shot super mega pixel mosaics, the Nodal Ninja is designed to eliminate parallax inherent when shooting adjacent images. Our panoramic tripod head is a quality piece of equipment designed to give you many years of use.
Nodal Ninja is shipped in its foam lined carry case and come partially assembled.

About Parallax

Parallax defined:

Parallax is the apparent shifting of a foreground object to a background object when viewed at different angles or perspectives. With panoramic photography, multi-shot images and mosaics, as well as QTVR’s parallax error creates serious problems. This is because each image shot is actually different from the one before it due to the minor shifting of objects in the field. Seamless stitching of adjacently shot photos is very difficult whenever parallax is prevalent. Things simply won’t line up properly.

Parallax Demonstrated:

Hold your thumb out in front of you at arm's length and view it with your right eye (left eye closed). Move your head back and forth while remaining focused on the background and you’ll see your thumb move back and forth – this is caused by parallax. The apparent movement of foreground objects to backgrounds and perspective changes. This is the same thing that happens when a camera is on a tripod. Tripods are NOT designed to eliminate parallax with panoramic photography.

Using a special head like the Nodal Ninja and adjusting it properly so it rotates about the "nodal point" of a lens will eliminate virtually any parallax.

Assembling the Nodal Ninja


Putting Nodal Ninja together is simple as it comes partially assembled.

1). Open the zippered case and familiarize yourself with the parts inside. You may or may not need all the parts.

2). Determine if the off axis camera bracket will be needed. Look at the base of your camera and note the position of the 1/4” female tripod mount. If this tripod mount is off center from the center portion of the lens you’ll need to use the small camera bracket.

Note position of tripod mount to the actual center of lens or barrel of the lens. Most small prosumers cameras have this offset.


3). Position the bracket so the adapters thread mount is directly inline with the lens axis. Tighten with small coin or screwdriver.

Note how the new camera mount is now inline with the center of the lens.


4). Next attach the vertical arm to the lower horizontal rail. You want to mount this with the upper rotator knob (FANOTEC markings) facing outwards. Slide this vertical arm to the outside of the rail before tightening.

5). Attach Nodal Ninja directly the tripod neck as shown above or a tripod head using quick release plate. Attaching directly to the tripod neck will give you a smaller tripod footprint if you need to shoot directly down. Attaching to an optional tripod head with quick release plate will also give you a bit more flexibility and ease in leveling the Nodal Ninja.

Mounting of the Camera

Mount your camera to the Nodal Ninja's upper horizontal rail. Depending on the camera and lens you can use different combinations as shown below. Note the hand grip of the camera is always positioned so it’s on top.

If mounting directly to the upper rail (without the off axis lens adapter as shown on left) make sure you use the wing nut and square rubber washer.

Positioning Camera to the Nodal Point of the Lens


What is the Nodal Point and Why is it Important?

The nodal point of a lens is the point inside a lens where light paths cross before being focused onto the CMOS, CCD or film plane. Although technically incorrect the nodal point is sometimes called the entrance pupil. When taking adjacent images you want to rotate the camera around a line that runs through (or very close to) the nodal point inside of the camera lens. By finding the nodal point of lens, and rotating the camera about this axis, will assure parallax free images. Parallax is more obvious to closer objects in the viewfinder. The more distant the objects the lesser the parallax. If using a lens with zoom capability the nodal point will change as the zoom change. Because of so many variables it is best to learn how to find the nodal point manually.
Now that your camera is mounted to the Nodal Ninja, as explained above, we need to find and set it up so the camera rotates properly around the lens nodal point. The nodal point will vary from lens to lens and will also vary depending on the focal length you use. We encourage you to learn to how to find the nodal point of your lens manually. Specific information you find elsewhere with respect to where a nodal point may be located on a lens should be taken with a bit of concern to accuracy. Once learned how to find your nodal point it’s relatively quick and easy. In this example we’ll use the popular Nikon D70 w/ 10.5 mm Nikkor lens.

Finding the nodal point:

There are only two adjustments needed – lower and upper. 1). Set the lower rail adjustment by pointing the camera directly down. Do this by loosening the upper "Fanotec" knob and rotate your camera to it is pointing straight down to the ground. Next loosen the lower adjustment knob, the one that tightens the vertical arm to the lower rail. Slide the vertical rail inwards on the lower rail until the lens is centered directly over the lower rotator. Once centered note the position on the ruler and tighten the lower adjustment knob. Your first nodal point is set and will not change regardless of lens or focal length.

Cheater note: On the 10.5mm Nikkor Lens the Nodal Point is located at the gold ring on the lens. But we’ll proceed as if we don't know this or if using a different lens.


3) Position in front of the camera two objects – one nearer than the other. For example indoors you could use two lamp poles or if outside try using two fence posts or light poles. Any two objects creating a vertical line will work as long as one is positioned behind the other. In this example we’ll use two floor lamps.

4) Looking inside the viewfinder, or at the LCD screen, rotate the camera so the two objects are towards the left side of the frame. Note the exact position of the two lamps. Ideally place the lamps so they aren’t directly behind each – slightly offset them. Note the apparent distance between the two lamp poles as shown below.

5) Now rotate the camera so the two objects are now in the right side of the frame. Go back and for the a few times and watch to see if the distance between the two poles change. If the distance changes, even slightly, then you have parallax and you’ll need to move the camera and lens slightly forward (or back) on the upper rail.

6) Loosen the wing nut and move the camera forward approx ½ inch (10 mm) and tighten. Repeat step 5 until the lamps remain relatively unchanged as shown below.

7) Note the position on both upper and lower rails. If you change cameras or lenses you’ll need to repeat the above steps. That’s it! It’s good to be close as possible to the nodal point, depending on the lens being used, sometimes it’s difficult to note much change with the objects set up. If you’re having difficulty noting object move (i.e. wider angler lens) when making minor adjustments try moving the lamp poles closer to the camera.
