How to Create a Panoramic Image in Photoshop
A panoramic image starts as a series of images, either handheld or shot on a tripod. The images are opened in Photoshop and stitched together to form a much larger composite.
Take a series of images. Overlap at least 1/3 as you rotate or pan to capture the next shot. Try rotating the camera to the portrait position for taller images.
In Photoshop, choose File > Automate > Photomerge....
In the dialog box, select Use Files and press the Browse button to navigate to your images.
To select your images, Cmd (PC-Ctrl) click each of the images in the sequence. Press Open.
There are six Layout options to choose from. Select Auto and click OK.
Photoshop calculates, aligns and merges. The stitched image appears. The Layer palette contains several image layers and layer masks.
Using the Rectangular Marquee tool, drag a rectangular selection that frames the image. Choose Image > Crop.
