This file naming issue is another good reason to use the ‘Edit in’ way instead of ‘Export’ because you don’t have to think about selecting the right preset each time. 
Also note that in version 1.10.0 of the stitcher the name handling was changed (although it’s not clear to me what is now working and what still not):
Wow, great information! Thanks.
I wonder what the bug fix was that was fixed on the Mac on 1/28?
Maybe people need to upgrade the plug-in and everything will start working???

Every few days, I read on Facebook about people having problems with the stitcher. Here’s another example of problem and solution. This one again relates to the file name. I am sharing again because the question keeps coming up and I am just trying to share the information widely.
My RAW images are coming out of the camera already stitched. Di I have a setting wrong or was there a Theta update that means we don’t need the extra stitcher anymore?
With normal usage, your RAW images should come out fully stitched. You don’t need to do anything to stitch them. If you want to get them in dual fisheye (maybe you want to stitch them yourself, maybe you want to take many pictures quickly), then you can use the DualFisheye Plugin.
Then why is there a special adobe plugin and a length forum thread about how to stitch them within Lightroom if you can just edit them in Lightroom already stitched?
On the Z1, the camera can take both a JPG and DNG image in dual-fisheye mode, meaning for one shutter press, you’ll generate two files. The JPG is equirectangular (stitched). Is it possible that you’re looking at the JPG and not the DNG file?
Yes. I am sure. I pulled the images off the camera instead of off the phone, they say .dng and are over 40MB each.
jcasman says that “your RAW images should come out fully stitched”.
I am so confused. 
Can you put your DNG image up on some place like Google Drive or dropbox so that we can take a look at it? My understanding is that the DNG image is normally in equirectangular. I have’t heard of a firmware upgrade to stitch the DNG image internally.
@Juantonto, great point.
@JPPeron, can you open the DNG file in Lightroom or darktable (which is free) and tell us what you see?
Example of opening DNG file from THETA in darktable.
Yes. I do. That is how mine are looking.
OH! It shows as already stitched until I go to the develop tab and then I get the two spheres.
Thanks for reporting back on the solution to the mystery. Editing the dual-fisheye DNG is new to many of us.
The light and clarity results from the expert people like Toyo are amazing.
I’ve been trying to collect some of the information on the process here:
https://www2.theta360.guide/doc/article/9
I’m slowly learning more about this process.
Becasue every DNG will save a smaller size preview image. If you generate a preview from the Raw data , you will end up with a dual fisheye image.
Actually, the DNG contains the full JPEG version (6720 x 3360 pixels) in addition to the raw data.
How to stitch raw photos with Ricoh Theta Z1 without using Adobe Lightroom or PTui. Any suggestions?
Thanks. Luc
