HDR plugin to automatically create EXR file. For VFX use

Just got a Z1 today, first thing I did was test this out with Blender. Awesome work! This app will make life so much easier, thank you.


Thanks for your post and congratulations on using your new Z1 with Blender.

I’m trying to get better screenshots of examples of use for the sites below. If you want to contribute any screenshots to help out @Kasper and the community, please post.


Absolutely! I’d be happy to help support in any way possible.


Really nice plugin! It exactly serves the purpose i bought the z1 for.
Thanks for developing this!

Some issues i encountered which i dont know if anybody else experienced:

  • one cycle of hdr creation with 9 stops and 3 denoise steps uses almost 10% of the battery
  • i just cant connect to on my android phone. My ipad connects without problems.

Curious if anybody else experiences this

Hello, error454

I recently took the first pictures on Z1, the plugin gives the best quality among all tried (not only standard) methods, so I would like to use it in the future. But the quality of stitching fails, I spent many hours in Photoshop to eliminate the effects of automatic stitching.
Here example:

I see that you have added a solution to this problem here:

But the fact is that I am not a programmer and cannot compile the code into a ready-made program for installation on the camera. So, please, could you uncomment this section of the code and post a link to the finished plugin so that I can install it on my camera?

Dear Craig,

Firstly, I want to express my gratitude and say that the photo as a result of the plugin is pleasantly amazing in its quality!

Please tell me, how can I disable automatic hemisphere stitching in the plugin? Automatic stitching often gives errors in the stitching line. Correcting stitching errors takes a lot of time in Photoshop.

Hi Artyom,

I’ve uploaded a new version to github which has the option to turn the stiching on and off in the webinterface. If you are a developer you can install the new apk on your device. (To become a developer you can follow one of the turotials on this community it’s not that hard.)

Else I will try to publish a new version to the store soon but I need a bit more time to finish some stuff and then Craig en Jesse have to push it to the theta store which usually tkaes about two weeks. So in total it will take some more time before it well be there.

The apk can be found here: https://github.com/iamagod/Authydra/tree/master/app/build/outputs/apk/debug



@Kasper Great to see that you’re still improving the Authydra plug-in! And, yes, happy to help if/when you want to push the next version up to the Plug-in Store!

I used the plug in one time then went to use it again and when going to I get a page that says

This site can’t be reached" The connection was reset. Try Checking the connection. ERR_CONNECTION_RESET Reload / Details

I searched the thread for some keywords I noticed someone had the same issue but I didn’t see a reply for advice.


Hey guys,

Using this plugin on a V, largely speaking, it’s pretty bloody great! However, having a few issues.
I’ve been testing it taking 3 HDR’s, with reboots in between.
When I connect to a PC after taking the 3 photos, 1st HDR is usually fine.
2nd, a bit hit or miss, sometimes it works, sometimes it doesn’t. A few reboots, connect/disconnect from PC a few times can sort it. The source jpegs can appear as 0 bytes, and the tone mapped preview jpeg can be broken, but eventually it seems to sort itself out.
3rd, pretty much always broken. No HDR or preview tone mapped jpeg has been created. The source jpeg files in the folder are reading 0 bytes. No amount of reboots/reconnects seems to nudge this. On a few occasions, it creates a HDR of the previous photos source jpegs, so I end up with a duplicate of the 2nd.

I have a shoot next week. So I suppose the workaround would be to take 2 HDR’s of every setup, offload to PC, delete off the camera, and start fresh for each set up :man_shrugging:

Any thoughts or anyone experiencing the same issues?


Hi! I had this problem, what worked for me was:

  • Connect to the Theta wi-fi network
  • turn plugin mode on by pushing the “mode” button on the camera
  • insert the address on the browser

Connected instantly!

Hope this helps!


Hi Dindong,

strange behaviour! Have you updated to the latest firmware? Also make sure the auto power off is set to something a bit long like 10 min or more.

I’ve just updated the app, usually takes a couple of weeks to get it in the store maybe that fixes your problem…

Hope that can help…

Thanks for your work. Do you have plans to update this plugin to work with the Z1? We’d be very appreciative!

This plugin is great job!
I have few issues.

  1. In my opinion the previous sounds was better. The new set of sounds is almost inaudible in the environment. Without connection to smartphone It’s hard to tell when the camera is done taking photos.
  2. sometimes it happens that after taking photos, the camera processes them almost endlessly or just turns off.
  3. I think that “Number stop jumps…” is not working. When is set for example to 2.5 the jump is still 1. Sometimes it’s not enough time take 13-15 photos in order to cover all exposures.
  4. Is it possible to add a feature like Merge photos in separate task? This is very time consumig especially when I want to take more than one hdr’s on a time on set. Yes I know that i’ts a lot of apps doing this job but it would be much simpler workflow.

Thanks :slight_smile:

I’ve never been able to connect to the web interface of Authydra. Chrome on a Pixel 4. Theta Z1 I’m connected to the wifi of the Theta but it just won’t connect to the web interface.

Realized I probably should have replied to you for my above question regarding web interface.

I used it once and now my Z1 won’t stay on. I get “ERROR” with beeps and that’s it. Hopefully I can find a fix but until then, avoid.

[edit] Make sure your firmware is up to date. If you do happen to get the ERROR on your device, just update the firmware once again through the Ricoh desktop app.

I’m loving this plugin but have noticed that one of the lenses seems to be capturing a different white balance. This problem doesn’t present itself when capturing with the native Theta software. Any suggestions?
