The Photomerge command offers six different layout options when creating a panoramic photo. Each method interprets the panoramic photos differently. We often try to run multiple methods to see which produces the best results. A good place to start is Auto, which attempts to align the images but will bend them as needed.
- Auto: With this method, Photoshop first analyzes your source images. It then applies either the Perspective, Cylindrical, and Spherical layout option. Photoshop attempts to choose which method to use that will produce a better Photomerge.
- Perspective: This method creates a composition by designating one of the source images as the center of the panoramic image. Photoshop generally picks the middle image, then transforms the other images around it. Photoshop will stretch and skew images as needed to overlap the layers and blend them together.
- Cylindrical: The cylindrical layout option works best for creating very wide panoramic images. The source images are overlapped in a way that looks like an unfolded cylinder.
- Spherical: The spherical option is best suited for 360-degree panoramas. The images are mapped to the inside of a sphere and can create a seamless image for use in specialty applications like multimedia or animation.
- Collage: This method only changes rotation or scale in order to overlap the content.
- Reposition: This method only changes the alignment of images, but does not transform (stretch or skew) any of the source layers.
