Hi Bruno, Not sure if I found a bug or if I am doing something wrong. I am using SVN4352 of 2009.2. I attempted to use the default arguments for autopano-SIFT-C, and I found that it indicates conversion to a stereographic projection in the control point generation window, even though an equirectangular projection is indicated in both the stitcher tab and quick preview window. It only finds 3 control points. When I remove the "--projection %f,%v" option it finds over 500 control points.
