Re: [PanoToolsNG] Which should be smaller, Nadir or Zenith?

      I am already at -15, and the three shots are to cover the zenith, which they do, but with not much overlap to spare. I doubt if -30 could be made to work... But if you're willing to try that could still lead to the optimum workflow.

      I'll see if my registration at GETT still works. I have the set of TIFFs I was playing with this afternoon, and can break those down into JPEGs.

      PS I suddenly realized that I could save considerable time and achieve greater consistency between all 6+2/3/4 shots by processing them ALL at the same time in PS ACR, and only using my favourite SNS HDR for the final panorama. SNS HDR is a bit slow if you use it serially, whereas ACR can be synched to apply to the entire series... Much faster.

      Hmm, if you are already taking 3shots to cover nadir try to go -15 or -30.
      If you can upload somewhere  a bunch of pictures in jpg (compress the jpg and let the resolution be high) I cam build a mathematical model aroun it and find the perfect workflow.

      I find that the nadir is rather uncomfortably big even when I point the camera/lens down by a full 15 degrees, but that I can cover the even larger zenith quite comfortably with three shots at an elevation of 60 degrees (120 degrees apart). As zenith shots are simple and quick to take, and align nicely with the six around, this seems an improvement on trying to get a good nadir shot that will cover a much larger hole.

      On the other hand, I am not totally happy with PS content-aware fill. It is not anywhere near as awful as it was, but still far from perfect.

      So when floors are flat I'll probably take advantage of the perspective change function and just tilt the camera/tripod/monopod/panorama-head assembly. And who knows, with practice I may be able to make better use of the NN nadir thingy.

      But I am hoping that when the programmable rotators are ready, I will be able to program them to take a complete sequence that will stitch easily.

      Hi Roger!

      Hi, Felipe!

      I shoot most of my panos using the Tokina 10-17 on a APS-C camera (Canon 50-D) mounted on a NN3 mk2. I shoot 6 horizontals tiltes about 12º down and one straight up for a total of 7 pics (21 if you bracket). I rarely shoot straight to the nadir (I choose an easy to clon spot down). Hope this helps.

      That is exactly what I wanted to know. Luca also says 15 degrees is too much. This afternoon I will be out and about trying different angles and processing. I will try both 10 and 12.5 degrees.
