Well, alright. We've now reached the point in our tutorial where we're just going to have some fun. Photo merge in Photoshop is an amazing function. I'll tell you why. It takes several images that you might want to stitch together to create one contiguous panoramic shot and just does amazing things and you've heard about it, I know you want to learn about it because you're looking at the tutorial. I'm going to show you how to do it. Now, these two images right here were shot, obviously in Vegas, and I think on this particular image I had five, five shots merge together. But on this one it was more like 16. I'm pretty sure I had 16 images that got merged together and photo merge did this and it's just, it's just unbelievable. I defy you to find the seams in here and I think that there may be one right here that you might be able to see and, you know, possibly right here, you know, maybe. But considering that it was an automated process and I really didn't have to do anything to finish it off, I was just absolutely dumbfounded about the result that we got on this thing when I got it done and if we look at this image, look at the detail in here. This is what you get. This is the benefit of doing stitching and, you know, putting five or six or seven images together to create one contiguous image is the detail because you're blending so much color and pixel information together. Now, this was shot with a Canon 1D Mark 2 from a distance of , and I'm going to guess 10 miles. I got a vantage point of Vegas, a secret vantage point that I go to and it gives me a complete 180 degree view of Vegas. Man, you can see everything. This is the Luxor with the light coming out of the top of it. This is the MGM. This is New York, New York, that brand-new one. And on down the street; Bellagio right there. And you can just see everything and if I printed this out it would a wonderful, wonderful thing. So there's the Vegas skyline. And we did this with photo merge. Now, here's how to do photo merge. Let me kill these two images. Photo merge is located under file, automate and photo merge and you click on it and up comes a dialog box and what you want to do is under layout, be sure you click reposition only. If you do any other, it coughs and spits and doesn't give you a good result. If you want the best result possible, click on reposition only. Then you got to grab your files and what you need to do before you go down this road is you need to take all the files you're going to use to stitch together and put them into one segregated directory, like I've done here. Now, these are the tif files. If I were going to put this together and my plan was to print the result, I would use the tif files. It takes forever to process because you're using larger files, 16-bit images and you start the process, go sit down and watch an episode of Andy Griffith, come back and it might be done. Ok? I'm going to use JPGs because I only want you to see the result. It's going to work a lot quicker. And we open and it will bring the files in here in this little box and then it's as simple as simply click OK and the program will cogitate and ruminate and it will jump around like you see here and then it just spits out the result. Wish I had a drum roll here because it would be apropos. Can you believe that? I mean, that's just amazing how incredible that is. If we look at it at a hundred percent, is that just draw dropping, unbelievable or what? You see any seams? No. Just amazing. Just absolutely amazing. Then we go to our layers palette and we see how, kind of what it did. It made masks for itself, it did clipping, let me show you some stuff here. Alright, look how it, look how it did all its own cropping. It made its own puzzle pieces and put them together. I mean, it's just absolutely unbelievable. All automatically in photo merge. Now, in order to finish this image off, what we do, now, why did I do that? Ok, we're going to flatten our image. Now, notice the horizon right here is crooked. Ok? And we want to fix that. Now, what do we do class? All together now, we get our Ruler Tool and we start up here at the Luxor way down here and we come all the way down to some part of Vegas and we let go, rotate canvas, arbitrary and we got a one-degree angle which ain't really too much and then it straightens. We go get our Crop Tool. We all remember what the Crop Tool is, right class? Everybody together. Very good. And we just reposition everything. You want to try to get as much of this into your result as you can. Maybe take it up to here because that's where the road ends. Pull it over here as far as it will go without going overboard. Double click on it and there you've got the finished product. And that took us, what, all of 90 seconds? The photo merge process in Photoshop is truly amazing. Now, next I'm going to show you from an equipment standpoint how you can do this at home. Now, you have a lot of people that will tell you you need to go out and buy all kinds of fancy clamps and dials and switches and software and all kind of tripod heads and all this stuff that costs, you know, hundreds of dollars and it just ain't so. Now, I did this with a Canon 1D Mark 2, 50-millimeter lens and the cheapest tripod you can image with a plain, old, everyday, run of the mill clamp.
