Control points inserted using Hugin which later integrate with panotools.
Exposures are manual using Panasonic Fx , mm focal length equivalent. It is better to use AI exposure. In Fx , AI means that it also adjusts for picture vibration but I notice that it prefers the largest aperture(i.e. the lowest aperture setting of ).
If each picture were to be optimised for its exposure, smart blend has the capability to blend the exposure, giving the impression of high dynamic range, similar to enfuse.
