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

This article contains

  • Links to example images processed from RAW DNG images from the Z1
  • How to set Z1 to take RAW(DNG) images
  • Configuration of Lightroom Classic CC Plug-in
  • Updates and information

The RICOH THETA Z1 is a major improvement over the THETA V, offering superior image quality and features such as RAW that are valuable for many industries, including real estate, tourism, training, construction, used car sales, and visual special effects (VFX).

Higher resolution and more color and light information in each picture mean greater detail on the zoom and better shots in low light or shots with bright and dark sections. The Z1 takes images at 6720x3360, a major improvement over the 5376x2688 of the V.

You can see great use of THETA Z1 DNG images by Sam Rohn in this article.

RICOH developed a plug-in for Adobe Lightroom Classic CC that makes it easy to stitch the RAW DNG images in a smooth workflow with Adobe Lightroom Classic CC.

I tested the RICOH THETA Z1 in early morning low light conditions. Even with my below-average photography skills, I found that Z1 handles the light/dark balance better than the V. I also compared the resolution and found that in pictures of my garden, the Z1 offers much better details of the leaves. For a better example of images, see the article on Sam’s images.

This update eliminates an old issue that caused a seam to form when using many of the adjustments in ACR. Removing chromatic aberrations is no longer a problem.

How to Set the Z1 to Take RAW (DNG) Images

Setting the Z1 to take RAW images is easy with the mobile app.

 

THETA Z1 Firmware update (Jun 8, 2021) Link

 

Noise reduction, HDR rendering and Handheld HDR are selectable when shooting with RAW (DNG)+JPEG mode.

 

Lightroom Classic CC Plug-in to Stitch DNG Images with Conversion to TIFF or JPEG

RICOH created a Lightroom Classic CC Plug-in to easily stitch the dual-fisheye RAW images into equirectangular format.

The DNG file is created alongside a standard JPG file.

Configure the Lightroom Plug-in To Use the THETA Stitcher

Please pay attention to the following screenshots for usage of the plug-in. Note that you must keep the filename of the stitched file the same as the DNG file.

As of RICOH THETA Stitcher ver 1.10.0 (Dec 19, 2019) you can change the file name as you like.

Within Lightroom Classic CC, the stitching app can automatically be called up at time of export.

After you press “OK”, an image is saved to disk that can be used in 360 viewers.

 

RICOH THETA Stitcher ver 2.00.0 (Apr 23, 2020)

・Batch process
・Changeable window size
・CVR Option added

Please note: Batch process stops every 20 images due to the restriction by Adobe (LrC). You need to restart it manually.

Warning; You always make sure CVR/OFF before stitching.

 

RICOH THETA Stitcher ver 2.20.0 (Nov 26,2020)


3 presets can be saved.

RTS

"Set to zero" (preset) would be very useful to correct Pitch/Roll and nadir when using Dualfisheye or Dualfisheye RAW plug-in.

If you have a good workflow for developing RAW (DNG) images without Adobe Lightroom Classic, you should consider using the standalone THETA Stitcher.

However, due to lack of human resources in the THETA division of RICOH, THETA Stitcher is not strongly supported. More discussion in the community would be helpful! If you use the standalone THETA Stitcher, please let us know about it and post your workflow and comments here: https://community.theta360.guide/t/sticher-stand-alone-for-z1/6243

Reference Information on Metadata and File Size

The metadata of the exported image is preserved. The test below was done with exiftoolgui.

 

As the RAW image format has so much flexibility, I spent additional time comparing the RAW DNG file to the JPEG file. The DNG file is 46MB in size.

JPEG images are 7.6MB

 

 

 

 

Summary

This is a first quick look at the THETA Z1 images. We have recently added excellent updates from community member Toyo Fujita, IKOMA360. The app is being steadily improved.

Due to the improvements in image resolution, light, and color data, the Z1 images offer much great flexibility for color and light editing compared to the images from the THETA V. The stitching app for Adobe Lightroom Classic CC is a great addition that allows the DNG images to be used easily. The increased resolution will also help computer vision and object recognition projects.
