How To: Edit and Stitch RAW DNG Images From RICOH THETA Z1 with Adobe Lightroom Classic CC and THETA Stitcher

@CorLeone, that’s great news! You should do a box-opening video and post it here. Let us know when you get it!

And, yea, I’ve looked for the Ricoh Stitcher online. I’ve looked here - - and I couldn’t find a link so far. I’m guessing with the Z1 now shipping that that will change soon.

OK, got it today and currently trying to get everything working (sorry, no unboxing video).

Fortunately, Ricoh also published the software (apps, stitcher, etc.) today as well!
However, the sticher is currently only available on the German page:
Not on the English page:
Is German preferred over English by the localization team? :wink:


Oh, @CorLeone, good eye! I went to look on the English site, didn’t see it. Nice sleuthing.

now on English site.


Tips on Using Stitcher

Problem: No compatible DNG files

Solution: Check filename and directory

The filename and the directory of the output of Lightroom Classic CC must match the original DNG file location and name.

More working examples

Example from Steve Swayne on Facebook.

Having explored some more, I now recommend using TIFF and not JPG as I showed in that screen grab. It seems the stitcher returns the file to Lightroom in the same format it gets, thus an uncompressed TIFF would be the obvious choice to reduce the introduction of additional artefacts and image degradation through another save into JPG format.


Steve, thanks for your help with these tips. This is all new to me and I could use all the advice you’re willing to provide. TIFF at 16 bits/compressed is good?

Thanks for this tip, Steve. Really helpful.

TIFF at 16 bits/compressed is good?

Yes, 16 bit TIFF is the right choice. You can also use Zip compression which is lossless but doesn’t gain much on photographic subjects (maybe 10-20%).

My initial tests show that going via the DNG workflow results in significantly better results than the out-of-camera JPEGs. Maybe I can post some examples later. Will also compare the Z1 with its grandma S (or is it the grandpa?) …


Here’s a sample image to illustrate my previous statement.

Just to give an overview of the scene, this is the DNG (scaled down):

This was taken with 100 ISO and f2.1.

Then two detail sections from this exposure …

First, from the out-of-camera JPEG (‘OOC JPEG’):

Second, from the DNG, developed in Lightroom (default settings, no tweaks) and stitched in Ricoh’s stitcher (AKA ‘processed DNG’):

Comparing the results shows:

  1. The size of the two images is slightly different:
    OOC JPEG: 6720 x 3360
    processed DNG: 7296 x 3648
  2. The OOC JPEG shows unnaturally saturated colors
  3. The OOC JPEG shows fewer details due to strong noise reduction and sharpening applied

This is all with default settings. The processed DNG can probably be further improved by fine-tuning the development.

Conclusion: If you want the best image quality, use the raw image data in the DNG file and an appropriate workflow!

(NB: What’s not visible from this sample are differences in the dynamic range. But, of course, the DNG is expected to win in this discipline as well …)


Is anyone else seeing issues with files that you have renamed before editing in Lightroom not working when exported to the Theta Stitcher app? From what I am seeing, the stitcher will only work with files using the file naming structure the camera uses (e.g. R0010003.DNG).

I shot some images yesterday and renamed the files to something like this: 2019-06-01-Plane-000001.dng. After editing the image in Lightroom and trying to edit it in the Stitcher, I get an error saying that a DNG must be in the same directory. Simply renaming the file to “R0010003.DNG” an exporting it again works fine.

I tried some other file names (e.g. “plane.DNG”), but the ONLY file format that seems to work is a capital R followed by a series of numbers.

Note: I am doing this on a Mac.

Yes, this is a restriction also documented in the help file for the stitcher. The reason for this is obscure to me.

BTW: I also don’t understand why the suggested workflow (as described above and in the help file) is using the export function of Lightroom. For me, it’s more natural to call the stitcher via ‘Edit In’ as illustrated in this screen shot:

My configuration for this is:

Using the export function would make sense for batch processing a set of images. But unfortunately, the stitcher currently only accepts a single image.

A UI-less batch mode stitching with default parameters or even specifying parameters on the command line should be on the list of possible improvements!

Hi, i try to use this plug’in but when i validate my settings in the plug’in and i clic on OK, i have this error

“Les images n’ont pas pu être traitées 0x00010505”

Translation of that
“Images could not be processed : 0x00010505”

Tkx for your help

Please post a screenshot of your Lightroom Classic CC settings with filename filled in

Hi, there is my setting

and my workflow

Thanks for posting this detailed information. I think the settings look okay.

Please post:

  • version of MacOS
  • Version of Lightroom Classic CC
  • amount of RAM in computer (needs to be 16GB or higher)

Hi, thanks for your Help.

Lighroom 8.1
Windows 10 64bit 2019
Intel HD graphics 4600 Open GL ???
but i only have 8gb of memory :confused:

I juste add 8GB of memory to reach 16gb and i still have this problem.

I do not have this problem, so I can’t test it. However, it might be worth updating your Intel graphics drivers.

What version of Windows 10?
