Photomerge
Photomerge automatically combines several photos into one panorama. Photoshop aligns the shots, blends the overlaps and corrects the perspective. That builds a wide, seamless image from a series of separate frames.
Choose File, Automate, Photomerge and load your series of shots that overlap by about 30%. Pick a projection method like Cylindrical or Auto and keep Blend Images Together ticked for a smooth transition. Photoshop delivers a layered file that you then crop and optionally fill at the edges with content-aware fill. Tip: shoot your source images with fixed exposure and white balance, so the panorama blends far more neatly.
