THETA Z1 DNG Image Editing Using Adobe Lightroom and PTGui

Photo Credit: Sam Rohn on Facebook. Original post

Photographer Sam Rohn recently posted some beautiful pictures taken with the RICOH THETA Z1 on Facebook. He took the images in DNG format and used Adobe Lightroom to edit the images. The results were really impressive! I was able to interview Sam online and got some additional tips.

Stitching Z1 Images with PTGui

Although RICOH announced that they will release a stitching plug-in for Adobe Lightroom in the future, Sam indicated that he used the third-party software PTGui to stitch the images as the THETA Stitcher was not available at the time of his test.

Joost Nieuwenhuijse of PTGui sent me this information:

The current PTGui can stitch images from the Z1 with some manual work,

basically by splitting the image into two separate fisheye images and then following 6.41:

Support / FAQ - PTGui Stitching Software

I’ll add support for the Z1 in the next PTGui update, it will recognize the camera, split the image and initialize the lens parameters. This will enable batch stitching. Stay tuned.

Alternatives to Lightroom

Sam indicted that open source darktable can be used as an alternative to Adobe Lightroom.


Using DNG can dramatically improve the color and light of THETA Z1 images. To get maximum benefit, photographers should edit the image light and color in software such as Adobe Lightroom. You can share really outstanding 360 images with your friends and clients on sites such as Facebook.

Adding some more examples of high quality Z1 imagery.

Thanks to @Juantonto (Link) for posting these images in his Twitter feed. His tweets say that he has a loaner Z1 from RICOH, has used HDR a little and noticed that the red dot does not show up.
