Tutorial 15

In this this tutorial I demonstrate just three of the many possible ways of levelling your Ricoh Theta panoramas — a question that seems to come up quite frequently.

Those three methods are

  1. The original RICOH THETA software (free)
  2. Using PTGui from a command line script
  3. Using Pano2VR — Bonus: Patch editing!

Links: My command line script, and the fabulous Exiftool.

This is Part 15 in a whole series of tutorials!

  1. Hi Florian,
    how do you preserve the Exif Data after patching and converting in Pano2VR?

  2. Basic question, I am shooting a 4 shot panorama with a 8mm fisheye on a tripod with rotator head. I take 1 shot at 0 degree position, then 90, then 180 and the forth at the 270 degree position. Next I need to take the up and down shots.. Question, do I rotate the camera back to the 0 position and then take the up down or do I leave the camera at the 270 deg. position and shoot the up / down shots there. I have seen tutorials that do it both ways.. does it make a difference. I use both PTGui and Panoweaver.. is the position software dependent?

    • Makes absolutely no difference. However, I would recommend you pick one and then stick to it as your own convention, because one day you might just have trouble bringing that zenith shot in on a featureless sky – then it helps knowing roughly what yaw it was shot at (0 or 270 ;-))

  3. Hi!

    I’m a bit lost here, I’m trying to execute your script but nothing happens, if I execute: “exiftool -All” to show all tags in the image from my Theta S there’s no info about Roll…???

    I have a licensed version of PTGui Pro.

    Thanks for all the tutorials, it’s been really helpful! 🙂

    • Hm, that’s strange. How did you get the file? Did you directly transfer it off the Theta with OSX’s Image Capture.app?

        • It seems like the pitch information no longer exists in the EXIF, maybe Ricoh has changed it? I’m running the latest firmware and software from Ricoh.

          Creating PTGui Project File…
          Error, missing Pitch information in EXIF!
          RolandMijersMBP:~ roleks$

  4. Hm, that is indeed strange. Either way, if the pitch / roll data is missing, then the script simply can’t do its work…

    • Sorry for my ignorance, I was using the Photos app and not the Image Capture App. Now everything works fine 🙂

      The Photos app strips out the Pitch and Roll EXIF when importing from the device…

      Thanks again for all your tutorials 🙂

  5. Hi Florian

    Thanks for the video!

    Do you know how i can get multiple images from ricoh all centered at north using the exif compass data?

    • I don’t have anything prepared, but it should be straightforward to hack something together based on exiftool (for reading out the appropriate EXIF field) and then Imagemagick’s convert (in order wrap/offset the image appropriately)…

  6. Hi Florian, hi guys,
    any of you have ever tried the classic nadir patching method with the Ricoh Theta? I mean the method of taking a first shot and then a second from a nearby position pointing to 45 degrees below horizontal and then taking the second shot what need to recover the ground or floor doing the processing in Ptgui. Like you do in the first tutorial. I think it should work. What do you think? Tks best, Valerio

    • Well it’s easier to patch in a small patch. If you take a whole 360 equi just for patching it’s a) overkill, and b) much more difficult to “fit in”… But given the small nadir area, it’s just retouch it rather than try to map in some pixels from a separate image.
