The approaches that have thus been developed by the different stitching software developers yield different numbers for optimal maximal resolution: the length and width of the equirectangular frame shall definitely vary. In addition, some software compute the optimum maximal resolution by assuming the successive digital transformations to end up in a final output where the equatorial line of the equirectangular frame is composed of pixels that were the least interpolated in the process. Software use different mathematical model for the concerned lens (be rectilinear or fisheye) and different mathematical model for the correction of the distortion required before warping the individual images. Many interpolations have to be performed in the workflow including correction of lens distortions, correction of aberrations and individual images warping, etc. You can read that too.There is no standard method to determine and to compute the natural resolution to expect from stitching individual photographs into a spherical (equirectangular projected) panorama. Use them - one or the other, or both, like me! You can’t go wrong.įinally, 360 Cities has its own Help site, including a page about how to create panoramas. If you want to learn panoramic photography, you should be happy that it is not 2005 anymore – these days, it is much easier, and it is principally because of the creators of the above two programs. Here is the PTGui support group and here is the Autopano forum. Whichever program you choose, you can post your questions and problems to their support forums, and you’ll get a quick answer, either from fellow users of the programs, or the authors themselves. The makers of PTGui and Autopano Pro are really smart and helpful guys. For this, PTGui and Autopano Giga work in quite different ways and it is up to your preference which one works better for you. Depending on how you shoot, you will need to fine tune the stitching and optimization of your panorama. Autopano Giga is especially for creating very large panoramas. The software I used to create the London Gigapixel is Autopano Giga (they also make Autopano Pro which is for normal panoramas). I used PTGui to create the Prague Gigapixel last year. I love it! I’ve used it to make literally thousands of panoramas (both normal ones, and gigapixel panoramas). The one that I have used the most is PTGui. If you really want to learn how to make panoramic photos, read his tutorials.įor software, there are a lot of different programs out there. He is truly a great resource of knowledge, and incredibly friendly with this tips. Houghton is a photographer from England, and he has been one of the most helpful people out there on various forums and mailing lists. My favorite tutorials for shooting spherical panoramas are John Houghton’s tutorials. It required some ugly editing of command-line scripts and stuff like that! Now it’s much easier, because the software for the creation of panoramic photos has come such a long way in the past few years. When I started shooting panoramas seriously, 6 years ago, it was much harder to create a spherical panorama that it is now. Usually I shoot “normal resolution” spherical panoramas, using a digital SLR camera and a fisheye lens. I don’t normally shoot these giant images like the London or Prague gigapixels. The better you get, the more tricks you learn, which allows you to do it even faster, and better. The more you practice, the better you get. There is nothing special about shooting panoramic photos.
