I don't know what's correct but this differs slightly from the pfstools: EV = (2*log($aperture) - log($et))/log(2) BV = (2*log($aperture) - log($et) - log(0.32*$iso)/log(2) -- View this message in context: http://old.nabble.com/How-Does-Hugin-Calculate-EV-%28Eev%29--tp27400199p27409116.html Sent from the hugin ptx mailing list archive at Nabble.com. -- You received this message because you are subscribed to the Google Groups "hugin and other free panoramic software" group.
