Panoramic cameras use assorted sizes of film and can expose an area with an aspect ratio of 2.5:1 compared to the familiar 1.5:1. There are two types of panoramic cameras, models that simply use wide-angle lenses and others that have a rotating lens that projects the image onto a cylindrically curved film. Some types of 35mm compact cameras can operate in a panoramic mode by just masking off the top and bottom of a normal photo frame. If you crop a normal image, you can also achieve the same effect. Some panoramic digital cameras are very costly and bulky. Some of them let you take 360 degree angle shots with no stitching. However, many compact cameras come with a panoramic mode which enables you to stitch the images together later on. This isn't useful for photos with moving objects though.
Other types of panoramic cameras are available, including models where the film moves past a slit shutter while the camera rotates. Some complex and costly digital models that are similar to this version are available. Fixed lens and interchangeable lens cameras are available. True digital panoramic cameras can cost over $30,000 while film models can cost several thousand.
