Tone-mapping is the step usually responsible for ruining HDR images. It turns out that most photographers considering HDR would actually prefer Exposure-Fusion which is a lighter process that produces readily usable results since there is no need for tone-mapping. The HDR capabilities of PTGui Pro are a great asset. The main difference is that PTGui allows control-points to be tweaked, so one can improve upon the automatic solution. It fails to correctly stitch objects at about the same rate as MS ICE, so slightly behind Autostitch. The automatic stitching is good and works well for the most part. PTGui Pro produces high-quality images with excellent sharpness throughout the frame and distinguishes itself by exceptional blending across seams. The final phase jumps to the Create Panorama tab which allows the usual parameters of size, quality, format and output file to be specified. This is also where the Pro version allows Exposure-Fusion and HDR blending to be enabled. It is then possible to review and edit control points individually, in case details were not matched correctly. while a drop-down menu offers a staggering number of alternate projections, 15 in total.Īlign Images positions and links them automatically. Projections: There are direct buttons for the most common projections Planar, Cylindrical, Spherical.Straighten Horizon: Automatically straightens the horizon to account for non-uniform camera movements.Center Panorama: Automatically centers the panorama.Set Center Point: Manually sets the center point of the panorama.Edit Panorama: This lets the panorama be moved and rotated along the projection surface.A number of really useful tools appear in the Panorama Editor toolbar: It can range from slightly choppy for a panorama of a few images to excruciatingly slow for a complex one. The interactive experience varies tremendously depending on the complexity of the panorama. This where parameters can be interactively modified by manipulating the whole panorama or individual images. The second window is the Panorama Editor. Obviously, such areas have to be in the overlap otherwise there will be discontinuities. The Mask feature is extremely useful for dealing with moving objects and lets the user paint over areas which are to be included or excluded from the panorama. The Load Image phase, for example, enables the Source Images and Mask tabs. This lets the user tweak any parameter and, to some extent, get a better understanding of how the process works.
