This time, I’m especially interested in the ability to add Android apps directly onto the camera itself. Last time, we didn’t have that.
We’re definitely covering this. Please bring a laptop with Android Studio installed. If you are ambitious, feel free to download and open this Android Studio project and see if you can build it. We’ll cover that step in the workshop, so no advanced preparation needed.
It would be useful to install Android Studio prior to the event because it is a large download and me take several minutes to install during the workshop.
Once you build the Android package for the camera, we’ll install it with the standard
adb install package.apk directly into the camera. You’ll be able to use the app during the workshop. We’ll then modify the application for your specific requirements.
You may be able to add still image watermarks or decoration (like a company icon) directly to the image taken by the camera. This might be good for an online magazine or photographer that wants to give themselves credit.
If there’s Android code to add effects or snowflakes, we can try it, possibly even prior to the workshop.
Attendees of the workshop will leave with a plug-in that can take 7 images in dual-fisheye that has different exposure compensation values.
I’d like to encourage people to consider finishing the plug-in and submitting it to the THETA Store.
There are three use cases that users are asking for right now:
- HDRI files for visual effects industry to record lighting data for 3D modelling
- HDRI files for tone mapping
- timelapse with 1 second intervals instead of 4 with the THETA V
The use case we have the most feedback on is the use of HDRI files for the VFX industry.
Current feedback on product requirements:
- 7 to 13 images
- 1/25000 second to 1/2 second shutter speed range
You can make a very easy plug-in that just does bracketing or take up the challenge of stitching the images internally and merging into an HDRI file or tone mapped image.
|bracket only||easy||post-production workflow to stitch images and then convert to HDR|
|timelapse||easy||post production workflow to stitch images and then convert to HDR|
|stitch internally||moderate||must save lens parameter information to camera one time, then convert to HDR post production|
|create HDR file inside camera||difficult||must first stitch all images, then convert to HDR inside camera|
Ichi Hirota has a commercial stitching library and application on Android phones. You may be able to license the library for use inside the camera. Other stitching libraries are available, but require work. You need a way to manually adjust for lens distortion then save the parameters inside the camera.
I will be there for the event August 30
Excellent, see you in a couple hours!
I’m updating Android Studio on my laptop and will load the project from GitHub
I did that this morning, downloading the zipped repo onto my laptop worked great. Did it on both a Windows laptop and a MacBook Air.
Attending with a guest. See you all tonight!
Great, we’re already setting up, looking forward to seeing you!
I would like to RSVP
Notes from meeting
Finishing Plug-in Tutorial
If people want to correct stitching errors when using Ichi Hirota’s Android application or PTGui, @Juantonto wrote a great tutorial of how to use GIMP to correct the stitch line.
Heat when live streaming
The HoloBuilder 360 SiteStream requires use of the HoloBuilder servers. If people need to get stream to YouTube/Facebook, they can consider the following:
- using a USB cable will reduce the heat
If you want to experiment with Wi-Fi streaming with the camera, you can try to attach heat sinks to the body of the camera or attach a fan if noise is not an issue.
In the past, people have created 3D printed models to hold small fans next to the body of the camera (design files for THETA S).
You can also try a normal fan and point it at the camera. A combination of the heatsinks plus a normal fan may reduce the problems.
Community member PC Chow contributed this idea:
Could you place a balloon over the bottom two third of the cam, the battery part, to protect from water, then tie,with rubber band, a miniature freeze pack, something like a bag of frozen pea, to the outside of battery area. You could exchange these freeze pack when needed.
I looked on Amazon and saw these:
Pictures for Events
Thanks to all participants! Great location at PubNub, really appreciate them hosting the event. Cool to hear how everyone is using their THETAs, from live streaming, to VFX, to crazy 360 degree videos on a bike changing out of one shirt into another while coming down Twin Peaks. (Seriously. There’s a video.)
Multiple people went through the workshop and successfully built a useful plug-in for themselves taking a bracket of pictures that can be turned into HDRi for visual special effects work. Very useful!
If you’re interested in programming for the THETA, let me know, we can get you going with similar tutorials and documentation!
Another successful developer
Lots of people networking.
Test with Google photos onebox
Dropping a note here to C Le who blazed through the tutorial and had lots of good questions. I’d like to follow up on your ideas for building an education plug-in that you could demo, but your email is bouncing. If you see this, please DM me: @jcasman
could you summarize some of the ideas?
Thanks. It’s the iframe link!

Nadir is clean. You are good GSV Trusted Photographer.
Oh, that’s cool. Nicely embedded in Markdown! Looks great. Thanks @Juantonto !
