In case you are a novice photographer trying to learn the tricks of the trade, or an experienced photographer who wants to polish his/her panoramas clicking skills, following article on panoramic digital photography is just apt for you.

Cylindrical & Fisheye Panorama - In Brief

Cylindrical panoramic is an image that is meant to be viewed as if seen through the inside of a cylinder. You can look at the image horizontally at a 360 degree. Cylindrical panoramic images are mostly used for shooting wide open exteriors or interiors where the floor and ceiling are of no significant interest.

Fisheye panorama is a wide angled shot that enables the coverage of a wide surface using a few images. Fisheye panoramas are extremely useful for creating panoramic views of virtual tours. Fisheye panoramas are easy to create and also the cost is less when compared to other types of panoramas.

What is the Difference Between Cylindrical and Spherical Panoramas?

By using cylindrical panoramas you can effortlessly capture any area in all directions. Cylindrical panoramas cover an entire 360 degree, except for the up and down view. Spherical panoramas on the other hand not only capture the 360 degree view, but also take into account the up and down view. Spherical panoramas are the best of the lot, as they can be taken without the tripod being seen or the photographer's shadow.

There are several advantages of shooting 360° spherical panoramas. 360° cylindrical panoramas are ideal for shooting panoramas of wide open areas and can be easily printed. The viewer can also get an overall sense of the place, as 360° spherical panoramas focus on the most significant aspects of the place.

How to Shoot Panoramic?

What all you need?

To create 360° cylindrical panoramas, you will need a camera, fisheye lens, a tripod and a panoramic head. By using a fisheye 10.5 mm lens, you will only need to take 8 photographs.

How to go ahead?
