Types planarcylindrical spherical cubic

martin florek7 Taking pictures choose a place turn and shoot overlap 30%

martin florek8 Taking pictures continued good tripod pano-head small aperture (high f-number) hyperfocal distance shoot verticaly wide angle spirit level remote shutter release no polarising filter

martin florek9 Problems brightness problems → manual exposure white balance → manual WB or shoot raw parallax problems → nodal point? [3] shoot to raw → very good idea :)

martin florek10 Parallax problem pictures from [4] solution - turn camera around “nodal” point it is the center of entrance pupil

martin florek11 Special hardware 180° or full 360° views in one shot hyperbolic and spherical panoramic mirrors circular fish-eye lenses

martin florek13 Software steps photos input, lens specification lens corrections – distortions, vignette, abberations control points selection images composition stitching brightness correction, blending cutting, export to output format

martin florek14 Hugin graphical interface for several free applications fully automatic with added “plug-ins” –Panorama tools – main engine, stitching, remove distortions –AutoPano – automatic corresponding points (patent on SIFT algorithm) –Enblend – blends images “without” seams
