The sun umbrella
Stitched panoramic picture, made of 5 series of 15 pictures each, using the panoramic head. The virtual "sphere" is almost complete, only the tripod zone is missing. Raw processing was made with Bibble 5.1, using default parameters. Autopano 2.0.9 was used for the stitching, with a few links manually corrected. Two versions of the same panorama have been generated. One with the "smartblend" mixer, which worked better in the bottom part of the picture, and another with the "multiband" mixer, which gave better results in the upper part. These two versions where exported to tiff files in order to retain as much information as possible, and then imported into The Gimp as layers. These layers were merged by hand, using the smooth selection tool in order to keep the best output everywhere. Export to tif, without the alpha-channel in order to be imported in Bibble. The layer tool was used in Bibble to enhance the contrast in the shadow of the umbrella.
