I just realized that the THETA X can take a single fisheye image at time.

This is a crop of the image.

Hi Craig,
Thank you very much for sharing this information. I’m relatively unfamiliar with Ricoh development thing. But I currently need to use this camera to capture some fisheye photos. Could you please recommend any entry-level tutorials that can guide me through using the code you’ve provided here?

Do you have an Android phone you can use to connect to the THETA X?

Yes sir. At least I can get one Android from my friend.

@craig This works smoothly for me. I’m using a Pixel 4 running Android 13. Using it with an X, running firmware 2.40.0.

I used the URL in Chrome to download the app to my Pixel 4. I got a warming message but did “install anyway.” No problem.

I run it. Choose the X from the bottom and get a screen with buttons (text only).

Here’s the output:

:hot_pepper: Thanks to a tip from @craig, I used the Image Capture app on my MacBook Air to transfer images over from my THETA to my laptop. Works great.

Thank you for the tutorial! I’m using the Nokia 4.2 with a rather vintage Android 11. I successfully connected and completed the fisheye setting. However, after tapping “take picture,” I couldn’t find any photos in the file checker. Do I need to use any software to retrieve the data output?

Once again, thanks for your help! It truly saved my day!

Edit: I find all photos by connecting the camera with PC. Thanks very much now everything is good!

oh, great news. If you connect the THETA X to your PC with a USB cable, you can see the single fisheye images, right? You may have to unplug and plug back in. Though, it seems like you figured it out. :slight_smile:

Great news before the weekend.
