![]() ![]() Note that for this to work, the scene has to be photographed multiple times using exposure bracketing and the EV exposure values set either manually in the hugin Camera and Lens tab, automatically from EXIF data or by optimising exposure in the hugin Assistant tab or hugin Exposure tab. Each of these bracketed exposure stacks will be exposure blended with enfuse and the results stitched together into a panorama with enblend. If Blended panorama (enfuse) is enabled then hugin will group the input images into exposure stacks by comparing positions, any images with more than 90% overlap are grouped like this. Further enblend settings can be found in the hugin Preferences.Įnable remapped images if you want to keep the intermediate images that enblend uses as input - For example modifying the alpha channel of these images and then blending manually is one technique for including and excluding people or objects that move between shots. In the final stitching process nona reprojects and distorts images to fit, enblend takes these images as individual TIFF files and merges them using sophisticated seam positioning and blending. If Blended panorama is enabled then enblend is used for blending. The following options determine which kind of image is created, and allow keeping the intermediate images created during the process. Hugin can output 'normal' stitched images, exposure blended images or high dynamic range ( HDR) images. The cropped-out areas are shown darkened in the hugin Preview window. Large 'gigapixel' style panoramas can be stitched in sections then blended later.When correcting perspective large areas of the panorama output will be empty anyway.The crop settings allow just a portion of the panorama to be stitched, there are various reasons to do this: Small images, it is better to create an Optimal Size image in hugin and downsize it later in an image editor such as the Gimp. Than about half the size of the Optimal Size will show aliasing artefacts. Note that the interpolation used by hugin doesn't handle downsampling very well, so output images smaller Have a pixel size of 3500 x 2480, a full screen spherical Equirectangular Projection image will have pixelĭimensions of 6000 x 3000 or greater and a gigapixel image has a pixel size of 32768 x 32768. Some examples: a three megapixel image has pixel dimensions of 2048 x 1536, an A4 print at 300 pixels per inch will Calculate Optimal Size will estimateĪ size that has about the same resolution as your input images. Set the width and height of your output panorama in pixels. Transverse Mercator has to be less than 180 degrees horizontally.Mercator has to be less than 180 degrees vertically.Stereographic has to be less than 360 degrees both vertically and horizontally.Panoramic (cylindrical) has to be less than 180 degrees vertically.Rectilinear has to be less than 180 degrees both vertically and horizontally.Note that some Projections have a limited field of view, notably: Hugin Preview window does the same thing. Output to fit the arrangement of the input images - The Fit button in the This is the horizontal and vertical angle of view of the output image,Ĭlicking Calculate Field of View will shrink or enlarge the field of view of the Sinusoidal, an equal area projection of an entire spherical scene.Trans Mercator, a mercator image rotated 90 degrees, suitable for displaying tall or overhead objects.A good projection for printing a 360 degree panorama. Mercator, a conformal cylindrical image.Objects in a stereographic image keep the same shape and show less distortion than simple fisheye. Stereographic, a conformal fisheye image.Better for representing a wide Field of View than rectilinear, but in many cases Stereographic Projection gives less distortion than simple fisheye. Fisheye, the same projection as a photo taken with a fisheye lens.It covers 360 degrees horizontally as well as the zenith and nadir. Equirectangular, the all purpose format for representing an entire spherical scene.A good projection for printing a 360 degree panorama, though you may prefer Mercator Projection. Panorama, actually a simple Cylindrical Projection as used by traditional rotating panoramic cameras.Use this if you are just stitching a handful of photographs together with a narrow Field of View or correcting perspective in a single shot. Rectilinear, this is the same projection as a photo taken with a 'normal' camera and lens.To choose from, each with different advantages and disadvantages: Here you can set the output Projection of your project, there are lots The rest of hugin is all about setting up the project and aligning images, the Stitcher tab is where ![]()
