Photoshop's Photomerge feature has completely automated the process of stitching together a panorama. It works even for non-tripod held panorama photos, like this one from my hike in the Swiss Alps.
The Photomerge feature works best if you use the panorama feature on your camera to assist you. If your camera doesn't have that feature, just remember to capture plenty of image overlap and try to keep the horizon in the same place in each photo. The steps:
- In Photoshop, open all of the image files you'd like to use in the panorama. (Photoshop requires at least 2 images.)
- Choose File > Automate > Photomerge
- In the Photomerge dialog box, choose Auto and click on the Add Open Files button. Make sure Blend Images Together is checked. Click OK.
- Crop, apply Curves and clone as necessary to achieve your final image.
This 5 photo panorama was taken on the Blumen (flower) trail from Bachalpsee to Waldspitz in the Swiss Alps.
