Now we will arrange the images into a grid: choose Project -> Align to Grid: To start we launch PTGui and load our 80 images by pressing the Load Images button, or by dragging the imagesįrom Explorer or Finder onto the PTGui window: (from 3744x5616) and the jpeg quality has been reduced considerably. To reduce the download size the images have been downsized to 2000x3000 pixels To follow this tutorial you can download the source As you can see the first 27 images contain only sky, with hardly any recognizable detail. Images without control points in such a way that the grid setup is preserved as much as possible.Īnd of course if an image contains only pure blue sky, small positioning errors will not be noticableĪs an example we have taken 80 photos with a 100mm lens of Paris from the Sacré-Cœur:Īt full size this will give a 760 megapixel panorama. The optimized panorama to the panorama prior to optimization (as set up by Align to Grid) and moving all In PTGui 9.1 and later will attempt to keep the panorama aligned as well as possible. Panorama by generating control points and optimizing.Įven if not all images have control points, the optimizer Not sufficient, we still need to align the Therefore just arranging the images in a grid is Will always be small positioning errors in the robotic head. This arranges all images into a grid of rows and columns. To overcome this problem a feature called Align to Grid has been included in PTGui, accessible from the Project Using a narrow angle tele lens increases the chance that a photo contains pure blue sky, only grass or a plain white wall.įor such images it's impossible to place control points since there is no recognizable detail. Smaller panorama, but in practise you'll often run into a problem: ![]() Stitching a gigapixel panorama is no different from stitching a psb file format supports panoramas of up to 300,000 pixels in width and length, PTGui has no problem stitching such extremely large panoramas. ![]() Lens panoramas of multiple gigapixels can be taken completely automatically. The robotic head will move the camera and release the shutter. Just set the number of rows & columns and press Start. NB: the shooting technique of each photo of the panorama is described in the article “ Photograph the Milky Way”.With a robotic panoramic head it's easy to take hundreds of photos at regular spacing.If there are luminous places in the panorama (light pollution), check that your settings does not overexpose them.Check that your tripod is (roughly) at level.Do not change neither the focal length nor the settings of your lens. Start with shots of the ground, then ground and sky, then finish by the zenith (some pictures will suffice). To create the panoramic image, you must take several rows of photos (depending of the focal length you use) from the ground at the zenith. Mountainous massifs are ideal, provided you climb on the heights. Such places have become too rare in Europe. You must preferably find a place with no light pollution on the northern horizon and on the southern horizon. ![]() Note that the Milky Way must not be too high in the sky (between 60° and 80°): it will will facilitate the assembly of the panoramic (there will be less deformations of the arch). That is to say from May at the end of the night until the end of September at the beginning of the night. The Milky Way must be high in the sky so that it is clearly visible on the images. I use a Bushman Gobi panoramic head that is very light and very compact. You must use a wide angle lens and a panoramic head, indispensable to create panoramics composed of many individual images.
