Thanks for the advise, I tool 3 different exposures but I was relying on autopano exposure fusion. I guess you get a better result if you do it manually. What program do you use to process your HDR images?
some pixels rows of the empy zenith of the intro pano can be seen so in panotour export cubefaces and in gimp, pse or ps etc. clone the sky pixels to fill the gaps... you could limit the maximim zoom more than you did (?) to avoid getting unsharp details.... as Desitiny said, brackets: onboard the DSLR cam most have 3 brackets +-2EV some nikons and recent (expensive) canons have up to 5,7 brackets a +-3EV... promote control from promotesystems.com can do also the job for canon and nikons... even without all that if you shot your images in RAW you could do pseud HDR/bracketing by exposing the RAWs +2,0,-2EV... autopano can handle the brackets, you can do it with external software for free too with EnfuseGUI and also with commercial tool photomatix and oloneo
Destiny just a quick question, do you process your images on HDR software prior or after stiching? I tried both but if I do it prior I get a funny ghost lines and if I do it after there are some alignement issues that photomatix can´t handle accurately.
