One of the fun things that I like to do is take multiple images across a scene and then stitch then together in a panorama. And one of the great benefits of doing this of course is that you can end up with a lot more information in a single file. So as a result, you can print the image much larger without having to have Photoshop re-sample or make up information. So we'll select the first series of images. I've go the first one selected and then I hold down the Shift key and select the last one. And then, in order to merge these together into a panorama, I'll select Tools > Photoshop > Photomerge.
Now, I get this dialog box where Photoshop asks me what type of panorama I want to merge together. If I don't know, I can simply click auto. But there are different options here. For example, the perspective option chooses the center image, in your panorama. So in this case, it would either be the third or the fourth frame and then, it transforms the other images, in order to fit or match up with those middle frames. If we choose cylindrical instead, it's going to blend the images but it's going to do it in a way that it tries to make sure that all of the images end up being the same height. Because one of the things you might notice if you choose perspective is that you tend to get this bow tie effect.
Where the center images are a lot shorter than the ones on the sides. If we want to shoot a 360-degree panorama, then we might want to try the spherical option. If we want Photoshop to limit the transformations that it does to simply rotating and scale the images so it doesn't distort any of the images, then we can use collage, and if we want it to. Do the least amount of distortions, meaning just align the layers and match the overlapping content but do not do any transformations.
Then we can select reposition. So I'm going to select cylindrical and then here at the bottom I'm going to choose to blend the images together so that Photoshop will make this a seamless panorama. And one thing that I were really taking care of before I exported these RAW files as JPEG files for the exercise files, I actually went in and opened them all in Camera Raw and I applied the Lens Profile Correction for each of the images because I want to hand off Photoshop the highest quality images that I can.
And in order to do that, I need to remove any of the distortion that might by caused by the lens. So I applied the profile which not only remove the distortion but also removed any extraneous vignetting. So I probably don't need to check on vignette removal for this set of files and the geometric distortion correction. This actually runs another algorithm that's a lot more complex. If you ever tried to merge panorama, and it just doesn't work, you can try turning this on and seeing if the more refined math will allow Photoshop to merge those files.
But, for the most part, it's just going to take more time, so I'll uncheck that, and then we'll click OK. Now, while Photoshop is making this panorama, we should probably talk about a few tips that might help when you're actually capturing the original frames. First of all, it'd be great if you could use a tripod. But if you can't, at least try not to move the camera much, and certainly you want to try not to tilt it. And you don't want to change the F-stop or the zoom when you're taking the photos. And you need to overlap each one of the frames by about 30% in order for Photoshop to find the overlapping or the duplicate information in each one of the frames.
So here we can see the resulting panaramas. You'll notice that over in the layers panel, Photoshop has actually kept each layer separate. And we can toggle on or off the eye icon for each one of these layers if we want to see which portion of which frame is being used. If we hold down the Option or the Alt key and we click on one of the masks, I think it's really interesting to see if we zoom in using command plus or command minus that Photoshop is using a very hard edge mask. It's actually going in there and cutting a very precise mask in order to create this seamless panorama. So I'll toggle back on the eye icon again by just clicking on it. And we'll zoom out using Command+0 or Control+0 on Windows. And I just want to crop away all of this extra white area around here. So with the Crop tool selected, making sure that I don't have any options set here.
If there are values, we can simply click clear button here. And then I will drag the crop marquee into my image to make sure that I'm cropping out all of that extra white area or that transparent area that I didn't quite capture in the original frame. And we'll just move this out a little bit. One shortcut to note, if Photoshop keeps snapping the crop to the edge, we can hold down the Control key. But you have to hold it down after you start dragging, so start clicking and dragging with the crop marquee and then hold down the Control key. And now I can get really close to those edges without Photoshop snapping to them. Then I'll choose the check mark, or we can tap the Enter or the Return key. And there is our finished panorama.
If we want to save some space because I do know these panoramas can get very large cause I see we're up to 81 megs I could use the fly out menu here from the layers panel and simply flatten the image because I'm pretty sure I'm not going to be moving around and of those layers or change any of the layer maps. So there you have it we've stitched together images from left to right, but you should also know that you can stitch vertically or you can even stitch a grid of images in Photoshop.
