Photoshop Image Stitching Tutorial

Photoshop Image Stitching Tutorial – Processing image sequences for HDR requires a separate process. And processing multiple images for a panorama requires a different process. So how do you create a panorama with multiple images taken for HDR processing? In this tutorial I’ll talk about how to do this using Lightroom’s HDR Efex Pro 2, Photoshop, and Nik Software.

The image below is one of the HDR panoramas I created. The panorama was created by stitching together 14 images in Photoshop. There are many images to collect. But here are the highlights from my portrait mode shoot. (as opposed to horizontal) But wait, there’s more! Each of the 14 images/quadrants was recorded using 5 different exposure levels for HDR processing. That’s a total of 70 images and lots of interior design!

For example, I took 5 photos from each of the 14 images that would make up the panorama. and set the exposure to -1.3EV, -0.7EV, 0EV, +0.7EV, +1.3EV. First, I combined all the -1.3EV images into a single panorama image. The -0.7EV images are then combined into another panorama, etc. The result is 5 panoramas separated by 2/3 points.

I recommend continuing to make image adjustments after your images are stitched together into a final panorama. If you want to make changes before cropping Be sure to apply the same changes to all of the images that will create the final panorama.

If you’re using one of these apps and Your panorama images are not the same size. You’ll need to resize your images before performing HDR processing. You can do this in Photoshop by opening any image and increasing the Canvas size (not the image size).

You can always trim later.

Select your 5 panoramic images in Lightroom, right-click on one of them and select Export > HDR Efex Pro 2.
