This is a sort of part two to a recent video that I posted on how to create panoramic images in Capture One software. As one commenter pointed out though, I didn't discuss finding the optical center of a lens. The original video is here: • Stitching Panos with C...
This short video looks at how to overcome the issue of parallax in photographing panoramas with more complex shapes inside them. In particular I use a leveling base on my tripod (built in to the Leofoto CEX range), and a small nodal rail - also from Leofoto - the NR-200. With this simple and light setup I can shoot perfect panoramas that don't struggle with parallex.
Please note that this technique is specifically for single-row panoramas. If you want to shoot multi-row panoramas a gimbal head is needed to get the actual nodal point (x and y axis) of the lens itself. I very rarely shoot multi-row panoramas (unless I have to create a VR or 360 degree image which is a different thing entirely). As such, finding the optical center along one axis through the use of a rail clamp is more than sufficient for single row panoramas.

Thanks! Yup, as I mention in the video, it is not essential to use this rig (and many photographers who insist that the only way is with a full nodal rig are probably trying to justify their own purchase of the big and heavy, and expensive, nodal rigs). If all you need is a single row pano, then using a rail to find the optical centre/entrance pupil/etc ensures that everything aligns neatly without too much computational wizardry from the stitching software.

You need to be sure your nodal rail isn't too long, if using a wide angle lens. I was using nodal rail that barely extended beyond the length of a 12-24mm lens, and the nodal rail showed up in frame at the 12mm range. Now I have 3 nodal rails. 100mm, 140mm and 200mm. Or, if wanting to have just one rail, you can get a double sided rail/plate without a built-in clamp and buy a double clamp that you can place anywhere you want on the rail.

Thanks for watching. If you aren’t using a system like this and you’re using the x system primes and want to try this, look for a slightly shorter nodal rail than the NR-200…or else be prepared to slice some of the rail off with an angle grinder. Lenses like the Laowa 9mm (which has its optical centre marked I think) are so short that the 200mm rail butts into the edge of the frame when shooting in the vertical position.

Another "thumbs up" for the Leofoto CEX tripods. I own two. HOWEVER, an alternative that I've actually come to prefer (in some instances) is the iFootage Gazelle TC6S. In addition to an in-built leveling head, the iFootage tripod includes a very useful center column and large, positive acting lever locks on the legs. Carbon fiber, of course. Excellent video, Emll.

Good tip about using the mobile phone. Thanks. I often shoot waterfalls which require more than one row of images (if it's a tall cascade), so I use a Neewer full gimbal head that allows measured tilt angle as well as pan angle but I too often manage hand held panoramas. One point you did not mention is that your rail might be too long for wider angle optics and thus appear in the image. An excellent explanation of measuring the nodal point. Thanks. subscribed.

@emilvonmaltitz Ай бұрын
Yes, for a stitch with multiple rows a full nodal head is the most accurate solution. I’ve had a discussion with another photographer about length of rail. It’s a good point. Using my 16-35 and 18mm f2.8 I’ve managed fine… on a DSLR. Mirrorless folks might need a smaller rail, or get comfortable with using an angle grinder to shorten the rail. As an aside, I have used the rail with a 12mm Laowa for a 360 degree room view, and the plate did intrude. But with that full setup (and that specific purpose) it’s easy to just not use that section of each image.

If you tilted the Ballhead down the Nodal Point is changing. You have to place a Rotator on the top of the ballhead and Rotate than. Maybe you can stitch the panorama together, but if you show this all the people here you have to do it right. A better ballhead is from Novoflex Germany you can place them upside down on the Threepod and you can rotate on the upperside.

I do this frequently with my landscapes. I like to preserve aspect, often using mid-tele to slightly compress - too retain the drama. You. ca. get some great results. Multi row and focus stacking (affording a more open lens). But you are right it is a lot of work and any movement can potentially. ruin the shot (wind or changing light). Oh well. This is the cross I bear. When works though ... it uniquely emmersive.

One trick to taking hand-held panos is to pivot around one foot. You plant one foot and rotate the other foot as you take each overlapped image. This emulates pivoting using the physical center of the lens, not necessarily the nodal point. It's not exact, but close enough for reasonable distant panos.

I think if, as a photographer, you’re worried about parallax, then you’ve gotten past knowing about manual everything. I mention it in the first video on shooting panos. Focus, exposure, white balance, everything has to be set to manual so that everything stays consistent exposure wise. Even though I use a CPL in the video I’d be cautious about using one where there’s sky involved as that shifts the exposure as you swivel the camera.

Tilt-shift is definitely more accurate since it’s two photographs of the same image circle. Swivelling the camera will change your shooting angle for each image. I used to own the Nikkor 28mm Shift lens purely for making panorama shots. Really enjoyed it, but it dod have an issue with vignetting which was a little more complicated getting rid of than simply pressing a button on the RAW converter.

Hi Stephen. If it's a single row it actually doesn't matter. You're still finding the axis of rotation. The best advise I can give is for photographers to try it themselves. I use this technique and it works. It is possible you'll find that you'll get better results from shifting the rail after tilting, but also after focusing. A lot of wide-angle lenses have quite signifcant focus breathing...but to be honest we're splitting hairs so finally at that point that it won't make a difference in your final image I suspect.

​@nuwanda923 You beat me to it: the axes of rotation (vertical and horizontal) both have to go through the PUPIL POINT (of the front element). That is NOT the same as either nodal point, but, as you said, you can find it by experiment. I was amused that the example Emil gave (mauve flower pan) showed very clearly he had NOT found the pupil point successfully - the leaves of the background moved left-right compared to the closer flower. Maybe that's what he intended to show and I was confused. The thing about parallax is that it affects the ability to stitch _either_ near or distant objects - you'll be able to do one or the other but not both. I love having a levelling head on a tripod. In fact I have a heavy Manfrotto video tripod I've modded for critical stills use. But most of my panos simply involve a lightweight stills tripod, and I level-up the panoramic head with a chunky ball head underneath it. I have a loose bubble level that just sits on the base of the pano mount. It only takes seconds and it keeps the kit compact yet high precision. I'm coming back to 360VR panos after a gap of quite a few years (I started using 35mm and a 17mm prime, back in the early 1990s, so the negs had first to be scanned-in!), and I was delighted to find that the Laowa 15mm f/2 actually has the pupil point marked on the lens casing. That's really handy. It has to be said that, if you want to do really creative stuff, you need to pay attention to this alignment detail, to within fractions of a millimetre. You can't just tilt your rail down and expect it to work. On the other hand, if you have a 360VR rig (and there are many brands nowadays), you position both rotational and vertical centres on the pupil point, and then your pictures should stitch at pretty much any angle of tilt. I have standardised my kit so that I need to make no adjustments in the field (apart from levelling). I've just finished making a new tilt arm for the pano head, which is exactly the right distance between the Manfrotto QR baseplate (for clipping on the camera) and the pivot. I now have a mirrorless body, and I can check the rotational alignment in seconds by using the camera's rear screen (zoomed in), with the camera looking vertically down through the centre of the pano head. That said, even my new Laowa is not immune to pincushioning, and it vignettes quite severely in the corners (nice for arty architecture stuff but a PITA for panos). Thus it's really important still to use a 50% overlap of images, horizontal and vertical, to ensure the stitching software has the easiest time you can give it. I'm expecting a better time shooting with my new lens, but the old one, a Sigma 12-24 zoom used at 12mm, needed 38 images for a complete sphere to stitch easily. I think the LAowa will get this down to something close to 20. Final thought: I use open source stitching software (Helmut Dersch's Panorama Tools, using the free front end _PTGui_ on Linux). There is one big reason, which is that there are tools built in that can salvage otherwise failed panoramas: Years ago, I crept out of bed at 4AM and went down to a beautiful little harbour on Lake Garda, to do a pano on the stone jetty, just after the mist left the lake. Nobody was about, and it was as still as anything, except the ripples moved the boats in the harbour just enough to put the tops of the masts in slightly different places between shots! I wasn't pleased to discover this back in the UK. It wouldn't automatically stitch at all well (who wants boats with bent masts?). It took a while but using masks (essentially a wiggly stitch, not a straight line), I could work round the problem, and in the final thing you'd never know.

I’ve found that if I talk about nodal points to photography students their eyes glaze over. If I say ‘optical centre’ the light bulb of recognition is very clear. But you are right. The correct term is nodal point.

Many sources that write “the rotation axis should pass through the lens nodal point” don't specify whether it is the front or rear nodal point, but either way it is incorrect. To preserve the perspective during rotation, which prevents a displacement of nearby objects relative to the background (parallax), the axis of rotation should pass through the entrance pupil, which is the center of perspective of a lens. No doubt instructions to experimentally find the position of the rotation axis will lead to the correct point, (as this good video gives) it's just that the designation nodal point is wrong. The good news is that, unlike a nodal point, the position of the entrance pupil can be approximately found by visual inspection. When you look into a lens from the front, the entrance pupil is the image of the diaphragm opening.

​@nuwanda923 lovely to see someone explaining this so clearly ... the word 'nodal' is one of the most misused in photography

Of course, if you’re doing a multi row panorama, then you need to find the optical centre horizontally and vertically

I responded in another comment that guaranteed someone would mention this 😂 absolutely correct, but that’s not the goal here. The point is that this is simple to use and light, whereas a full pano gimbal is heavier, more complicated to set up and - for the good ones least - significantly more expensive.

It is not the optical sensor that you align with the center of rotation, it is the no parallax point of the lens (sometimes called nodal point).

My guess is you misheard me. ‘Optical center’ not sensor. Which is another description for the nodal point.

Hello, sorry but I think there is an error. The axis of rotation must pass through the pupil of the lens to avoid parallax. In the movement of your example the axis is perpendicular to the ground and the pupil is making a translation.
@emilvonmaltitz
@emilvonmaltitz Ай бұрын
And yet it works. I know that the pupil is supposed to be where the aperture blades are but zoom lenses as used here do change where the that point is depending on the optical formulae used. The crazy thing is, how I describe in the video works. Try it and see.

So strange how many pano photographers don't understand the calculation, or observation, of a lenses "perspective center", which is, after all, the point around which the outfit needs to rotate to achieve distortion-free (or distortion-minimized) images. A couple of metre sticks, some string and nails, or one image, with two 'rulers', located at different distances, and some trigonometry.

Absolutely, but as you say it’s extraordinarily time consuming… to the point that you could lose the shot because it takes too long to set up. Once you’ve used a leveling you’ll never know how you worked without one

@@emilvonmaltitz With your setup, the pano picture won't be base on lens's optical center. still have parallax witch obviously shows on the sample video. so it's not the "perfect pano". it's must need a clamp like rrs pc clamp to close to shoot "perfect" 1 roll pano.

Great explanation. Despite the 'expert' dissing comments it works for me and is easily transferrable to multi-row panos, Brenizer technique etc with just a little more kit. Thanks, it has prompted me to get out and do some.
