Results of stitching 4 fish eye images into a 360 spherical image. It is also possible to print the rectangular stitched image.

The panorama is then converted into a spherical movie that can be displayed on an LCD monitor, computer or TV screen.

For best results I use the camera in manual mode so the exposures are all identical and use f/8 or f/11 for good depth of field.įour images of the McDougall church near Morely, AB taken with my 8-15 mm Canon fish eye lens and stitched together using PTGUi software into a flat 360 panorama below. The zenith and nadir photos are sometimes not needed when photographing outdoor scenes, but are essential for indoor photography if the floor and ceiling include textures and patterns. The easiest method to create a 360 spherical panorama is to use an 8 mm fish eye lens on a full frame camera and take 4 photographs at 90 degrees to each other, then one shot straight up (zenith) and one straight down (nadir). While almost any lens can be used to create spherical panoramas longer focal length lenses require more images to stitch them together. Some programs also offer the ability to customize various interface features or add snow and rain. PTgui can save the stitched panorama as a flash (.swf) movie, but there are several other programs that will also save spherical movies in HTML 5 format that does not require the Flash plug-in so they can viewed on mobile devices. Photoshop CS6 does not stitch 180 degree spherical images reliably, but is used to enhance the panoramas and fix the top (zenith) and bottom (nodal) regions of the images. Hugin is a free program that stitches spherical images, but I have not used it. The easiest method to capture 360 spherical pans is to take a series of photographs using a full-frame fish eye lens and stitch the images in software such as PTGui. In addition there is also a growing interest i n moving 3D spherical movies - in these images a camera is pulled or moved through the scene to capture a real movie that you can turn around in while it travels.ģ60 panorama of the Castle Junction Bridge in Banff National Park, ABīelow I describe the basics steps for creating spherical panorama images and I have added links to other sites that include more detailed descriptions of the equipment, software and methods. Google is also popularizing spherical imaging and has created virtual tours embedded within their street maps. There are also other programs available to stitch images into 360 panoramas (see links below). Dersch's software and is now available commercially. PTGui is a stitching program built on the basis of Dr. In 2006, IPIX filed for bankruptcy, many of its patents were sold and this also allowed other companies to develop alternative spherical stitching software. Helmet Dersch who had created his own stitching software and released if for free, but had to take it down because of the high cost of defending himself and this created ill will in the VR community. Unfortunately the high cost of making spherical movies, their poor quality and the aggressive marketing tactics used by IPIX lead many photographers (including myself) to avoid using their proprietary software.
My first attempts were made with a compact Olympus digital camera and a small fish eye lens.

Back in the late 1990's there was a method to make spherical panoramas using proprietary software provided by IPIX, but the company charged a license fee to create each movie of $25-75 each.
I have been photographing panoramas for over 10 years and making movies out of them, but my earlier movies were tubes that did not allow a visitor to look up at the sky or down at the ground ( see my earlier article and tutorial on panorama photography). It's also possible to link one movie to another in order to create a virtual tour with hot spots and add music, narration, video, text, expandable maps, and animated radars that turn in the direction the movie is pointed. Spherical panorama photography involves stitching a series of images together to create an entire 360 sphere that with the right software can be converted into an interactive movie using QuickTime VR, Flash, Java or HTML 5 with Javascript. Watch animation and note it is snowing in the panorama.
