Panoramic pictures are actually simply a number of pictures stitched collectively to make one actually broad photograph. There are completely different sorts of panoramas, all of which will be taken to the following stage when shot with a drone. All of them have roughly the identical course of for taking pictures and modifying, however you’ll be able to select to get inventive when stitching them collectively.  Be taught extra about the right way to create interactive 360 diploma panoramas by testing our current put up on the topic.

Taking pictures

  • When taking a panorama, at all times shoot in handbook mode. As a result of we shall be stitching a number of pictures collectively, it can be crucial that the entire settings keep the identical between the pictures. When taking pictures in automated, the digicam may change publicity or white steadiness barely between pictures.
  • Be sure you are taking pictures in RAW. The best technique to sew them collectively later is in Digicam Uncooked, which wants RAW pictures, not JPEGs. This additionally permits for rather more detailed modifying and shade firming.
  • Place your drone within the air at no matter top you select (I feel it really works properly at about 100-200ft).  Take your first photograph, and rotate the digicam about 45 levels to the fitting. Be sure that a minimum of 30-40% of the second photograph overlaps with the primary photograph to make sure that Photoshop has sufficient data to sew the pictures collectively. Activate the grid to assist information you.  Repeat this about 3-10 occasions, or till you’ve captured the entire panorama or returned all the way in which again to your place to begin.

Apps & Automation

There are apps that may automate this course of for you, equivalent to Litchi or DronePan, or you are able to do it manually. I’ve discovered that doing this manually leaves room for error, and this may trigger points when stitching the pictures collectively later. It’s fast and simple to make use of an automatic app, however a few of them do value a bit of cash to obtain.

**Tip for taking pictures: While you go to sew your pictures collectively, it may be exhausting to inform the place panorama ends and the following one begins you probably have taken a couple of consecutively. So if you end up taking pictures, take an image of one thing else, equivalent to a photograph straight down on the floor, in between panoramas. This manner, if you end up going by way of your digicam roll, it’s simple to inform which pictures belong collectively in a single panorama.

Modifying

Upon getting your pictures, import them into Digicam Uncooked and edit them as traditional. One vital step is to you should definitely activate profile corrections to eliminate any lens distortion. This may assist mix the pictures collectively seamlessly and assist to keep away from continuity errors. To make sure the modifying on all of them is constant, edit one nonetheless you need, then choose all of them press Alt + S. This may open up a dialog field with an entire bunch of checkboxes. Be sure that they’re all checked, then click on “Synchronize.” The entire edits you made will now be similar on the entire pictures. Your group of pictures ought to now look one thing like this:

On this instance, I rotated my digicam 360 levels across the bridge, so the primary photograph picks up the place the final one leaves off. This manner, when stitching, you’ll be able to select any phase of the sequence, utilizing only a few or the entire pictures to get completely different outcomes.

Common Panorama

DronegenuityTo sew collectively a conventional, rectangular panorama, import your entire pictures into Photoshop.  Choose all of them, proper click on, and choose “Merge to Panorama.” This may open up a dialog field with a couple of choices. On the fitting facet, there’s a part known as “Projection,” the place you’ll be able to select Spherical, Cylindrical, or Perspective. This modifications the way in which that Photoshop places the photographs collectively. Fortunately, Photoshop provides us a preview of how every one will look, so you’ll be able to click on every one and see which you want the very best. Relying in your topic, how shut it’s to you, and the attitude you will have, completely different ones may look higher than others. Additionally, typically a number of of the modes may not be an choice primarily based in your pictures. Strive all of them to see which one seems to be probably the most correct. Beneath that part, there’s a field marked “Auto Crop” and a slider marked “Boundary Warp.” As a result of Photoshop has to warp the photographs a bit, there shall be some jagged edges and white house across the exterior. You possibly can both crop this off, or use the boundary warp to stretch and skew the picture to suit right into a rectangle. I like to recommend utilizing the boundary warp as a result of cropping would lose among the data from the photograph, whereas boundary warping retains the entire pixels. Click on “Merge” and select the place to save lots of your new picture. Photoshop then provides your panorama to the tip of your digicam roll in Digicam Uncooked, the place you’ll be able to export it as a JPEG.

Tiny Planet

DronegenuityOne other enjoyable factor to do with a panoramic photograph is make it right into a tiny planet. They are often made with regular pictures as properly, however work particularly properly with panoramas. To make a tiny planet, take a traditional panorama, similar to the final one, and open it up in Photoshop. We have to mix the fitting and left edges, in order that it isn’t apparent the place they join. Choose a small rectangle on one facet, and duplicate and paste it on the opposite facet. Click on Edit, Rework, then Flip Horizontal. Then masks out elements in order that it blends. Make every other changes needed, then choose the entire layers and use Command + Shift + E to merge the entire layers collectively. Choose the picture, and use Command + T to remodel the picture. Squish the picture till it turns into an ideal sq., then crop off the additional white house. Flip the picture 180 levels so it’s the wrong way up. Choose Filter, then Polar Coordinates. Chances are high there may be some distortion within the sky, so make changes as needed. And there’s your tiny planet!

When Issues Go Improper…

1. Distorted horizon line:

I’ve discovered that the simplest technique to repair a distorted horizon line is to make use of the “Puppet Warp” perform. To make use of this, open up your panorama in Photoshop. Choose Edit, then Puppet Warp. This could make one thing like this pop up:

Dronegenuity

I’ve discovered it a lot simpler to show this off by unchecking the field up high that claims “present mesh” and as a substitute, use the grid. Use Command + ‘ (apostrophe) to toggle the grid on and off.

Drop pins alongside the horizon line, then drag them to line them up alongside the grid. This may assist appropriate distortion in your horizon line and preserve it as straight as attainable.

2. Error Messages

Whereas I used to be experimenting with panoramas, I got here throughout a number of dreaded error messages.

The primary one seemed like this:Dronegenuity

Fortunately, this one is simple to repair. Within the Panorama Merge Preview dialog field, merely choose a unique projection choice (spherical, cylindrical, or perspective). Not all of those choices can be found for each set of pictures that you simply attempt to merge, so if this error pops up simply decide a unique one.

The opposite error messages I obtained included these two:Dronegenuity Dronegenuity

The primary one signifies that a few of your pictures merged collectively, however others had been not noted.

The second signifies that Photoshop couldn’t discover sufficient matching factors to sew any of your pictures collectively right into a panorama.

You possibly can strive a couple of issues to repair these issues. First, be very cautious to ensure your horizon is in the identical place in your entire pictures. If the horizon line is off in a number of pictures, Photoshop may need a tough time finding factors to attach. Subsequent, make it possible for there may be sufficient overlap in your pictures. You wish to have about 30-50% overlap from one photograph to the following to make sure that, once more, Photoshop can find sufficient connecting factors between the pictures. To keep away from these issues, strive utilizing one of many automated apps that may take the pictures for you. DronePan or Litchi will take all of the guesswork out of taking panoramas, and can cut back the possibility of getting one in all these error messages. Additionally, you may strive utilizing a unique mixture of pictures. Typically one or two are usually not fairly just like the others, so strive leaving one out or utilizing a smaller quantity of pictures. But when all else fails, strive utilizing a unique program. Lightroom additionally merges panoramas, and the method is sort of similar. There are additionally tons of different applications you may strive, equivalent to PTGui, however they probably require subscriptions.

3. Continuity Errors

DronegenuityLastly, typically we get issues like this in our panoramas. Photoshop makes an attempt to attach comparable factors, however doesn’t at all times get it fairly proper. At all times zoom in shut to ensure every thing is lined up, particularly across the horizon line. If there may be an error like this one, deliver the photograph into Photoshop and use the patch software or clone stamp software to restore it.

And that’s a fast tutorial on the right way to shoot, edit, sew, and repair panoramas with a drone. Now go shoot your personal panoramas and share them with us!
