There are brackets designed specifically for that purpose and they are quite expensive. You need to find the camera's nodal point and be able to rotate the camera around it. Ease of use - precise stitching of a 360 degree panorama requires skill.The Theta has several advantages over more traditionally stitched panoramas: In the case of the Ricoh Theta, it uses two fisheye cameras to produce a 360 x 360 degree view.Ĭompared to other 360-degree cameras, the Theta is priced competitively, and is smaller and more portable. The BublCam ($799) uses four cameras in a tetrahedron formation in a ball-shaped body to produce a complete 360 x 360 degree spherical view. For example, the NCTech iris360 ($1,999) camera uses four cameras to produce a 360 x 295 degree view. That is the approach used by cameras such as the Kodak SP360 and 360fly.Ī newer approach is to stitch a panorama but instead of using one camera to take several shots, they use more than one camera to take several shots simultaneously. A variation on this approach is to use a very wide angle fisheye lens and point it upward, so the periphery provides a seamless 360-degree view (although the vertical field of view is around 235 degrees or less). The disadvantage of the catadioptric approach is that it will have a relatively large blind spot along the stem of the mirror - the thicker the stem, the larger the blind spot. Previous digital cameras used a similar approach, with stitching either done internally, or in post-processing.Īnother approach was to use a 360-degree mirror which would reflect into a lens (catadioptric design). Previous methods relied on the camera taking several photos as the camera is rotated.
Panoramic cameras have been in use as early as 1843. Note: For images here with the Ricoh Theta logo, such as the one above, you can click on the images to view the photosphere (as long as your browser supports it). In this post, I review and compare the three models, with an emphasis on the Theta S. I had the original Ricoh Theta, the second-generation Theta m15 model, and I now use the third-generation Theta S. While there have been other cameras that can take 360-degree panoramas, the Ricoh Theta strikes a very good balance of usability, image quality, and price.Ĭhristmas eve dinner #theta360 - Spherical Image - RICOH THETA The Ricoh Theta is a unique camera that shoots 360-degree photospheres. The Ricoh Theta S serves that function very well. Especially in this age of social media, photos help us share our stories with friends and family. Many family photos are taken for documentary purposes, i.e., to memorialize events and places we've been to. Separate from the increasing interest in VR shots, I think the Ricoh Theta S is a very good camera for family photos and vacations. Unlike panoramic photos with some cameras and phones, the Theta S captures its photospheres with a single shot, making it possible to capture movement and action in real time. The Theta S takes photos and videos with 360-degree horizontal and 360-degree vertical field of view. It is the third generation of the Theta, which first came out in 2013. One such device for capturing photospheres is the Ricoh Theta S. While much of the spotlight in 2016 is on virtual reality devices such as the Oculus Rift and Playstation VR, part of the trend is the increasing number of 360-degree cameras that can capture photospheres.
