Join Richard Harrington for an in-depth discussion in this video The Cylindrical method, part of Creating Panoramas with Lightroom.
- Alright, now that you've mastered the perspective method, Let's switch to the cylindrical method. This is best for very wide-angle panoramas. So if you have a lot of shots, even up to a full 360, the cylindrical method tends to work the best. The benefit of cylindrical is it does a good job of eliminating, sort of, the bow-tie effect that we saw with the typical projections methods. Remember, when you look at the standard shape here, and you look at the crop, you see that perspective tends to make a bit of a bow-tie shape.
Alright, let's take a 360 panorama here, 24 shots. This is the Red Rock area in Las Vegas, Nevada. Let's take this 360. I'll select the entire stack, and press Ctrl m to invoke the merge. Let's choose the cylindrical method. Now, this method will take a while with all of the images selected here. So, it may take a substantial amount of RAM, and a good bit of time. If it fails, you might not have enough memory in your computer. There we go, and with the auto crop on there, it removes some of those other areas.
Let's uncheck Auto Crop for a second. And you'll see that this was a fairly well-shot panoramic photo. Now, it wraps all the way around the cylinder. If you see this brick here, you'll notice that it picks back up here on the other side. And, this little divot here is really a straight line. What happens with the 360 is things wrap off from one side, here's this truck, and pick back up on the other side here. So this is a full 360 degree image. Let's choose Auto Crop and let it trim the top and the bottom.
And, when I give that a look over, if I'm satisfied, I'll just click the Merge, and it will generate the new DNG RAW file. Remember, this is still a RAW file. So after the fact, you can easily go in and enhance the images. That merging is happening. And we can track the progress up here in the left corner. It's a pretty large file so it's going to take a bit to complete the merge. But once it's done, any of the adjustments that you've made so far are available. You'll notice that there is a substantial overlap between each image.
In fact, it's almost 50 percent. Having this large amount of overlap makes it very easy for the panorama to successfully merge. Also, it's going to build the panorama from sort of the middle. So anywhere around image 12 or 13 will give you a pretty good idea of where it puts the middle at. It's this path here. Now, that's the technical center. But because this can be wrapped from side to side, you'll notice that it's really, essentially the inside of a cylinder.
And if you wrap this around the tube, the two edges would meet up. Now, if we go back in and try to merge this another way, Let's just select that stack there with it closed, and I'll invoke the merge again. And, I'll choose a different method here. Such as spherical. We're going to tackle spherical more in just a moment. But I want you to see the difference between the two. It's pretty minor in this case. But it is going to create a similar effect. What you'll see is a bit more of a stretch vertically.
With the spherical method there, if we turn off the crop, you see that the negative space, or the empty space, is just a bit different. But in this case, cylindrical was the best method for that 360 degree pan. Alright, let's click cancel. And we'll go on to the last type.
