On occasion, you encounter a vista that is so broad and interesting that, even with an ultra-wide lens, it cannot be photographed in a way that replicates the impact seen by the eye.
This is the time to create a panoramic composite. To do this I hold the camera in portrait mode (held vertically), choose a suitable aperture and ISO setting, and take a meter reading from a central part in the image. The camera is then switched into manual mode and the settings adjusted to match those previously noted. I then shoot a series of heavily overlapping images capturing the full breadth of the scene.
The series of images are then loaded into Photoshop and stitched into a single panoramic photograph which is then tweaked and edited as I would do with any normal shot.
