Hi guys, I see from a older post that the 14mm isn't the first choice for spherical panos and that the 15mm is a better choice. However the 14mm is what I already own and would like to make it work. I have used a (borrowed) 15mm and like it (I know, some will say, keep borrowing or buy it :. I have been testing the 14mm by shooting +45¬?, 0, -45¬? with 6 shots per row. I'm pretty certain of my NPP settings of upper arm 91 lower rail 53.5. But PTgui is having a tough time with the images. Am I shooting too many/not enough, wrong tilt angles, etc.? Thanks for any help.
