3D/VR Stereo Photo Viewer App

3D/VR Stereo Photo Viewer

It seems like it has been a long time since my last post, because I have been very busy coding, testing, and writing. Especially in the last three weeks, when I published and polished my new 3D/VR Stereo Photo Viewer app for Android Google Cardboard VR head mounted devices. I also built a supporting web site. It's a for sale app on the Google Play Store, and is an upgrade from my free app 3D Stereo Photo Viewer. You can find it at:


The web site supporting these apps is http://www.tekla3d.com

Why buy this app when you can get the free version??

The answer is that you can use the app with Google Cardboard VR headsets. The app corrects the lens distortion that occurs with Cardboard style headsets, yet it can still be used with smart phone stereoscopes, same as the free app. In the free app the distortion of the lens in Cardboard VR may not bother you depending on the photo, but you will only see the center of the photo close up in the Cardboard HMD due to the immersive viewing effect of these headsets for VR.

With the paid app you can zoom in and out of the photo and reposition your viewing window over any area of interest in the photo. You zoom in by rolling (airplane roll) the HMD to the right (i.e. clockwise) and zoom out by rolling to the left (i.e. counter-clockwise). You reposition the viewing window by moving the headset left/right (airplane yaw) and up/down (airplane pitch). By moving your headset to zoom and reposition, the result is similar to making a temporary photo crop. This will be of interest depending on the photo subject.

The app will also automatically detect when you reposition out of the photo. Then you can click (pull lever) or enter key on a remote controller to get back to the center.

The advantages of the zoom feature are:

  1. Zoom-in  will show photo details you might otherwise miss. And you can see much more detail when photos are sized to 4K (3840x2160 pixels) for each eye, and stored as individual left and right photos. This works well even for phones that have 1920x1080 display resolution.
  2. Zoom-out allows you to see close foreground subjects with more eye comfort.
Other new features in the Cardboard VR mode use two remote bluetooth controller keys for viewing with a headset. These features replace the keys used for Camera cha-cha and Menu..
  1. When you view 3D photos from web sites, some of the images in a web page may not be 3D. A remote key (volume up) allows you to switch to 2D mode showing the same photo in each eye, do you don't have to open the HMD to change your view.
  2. Sometimes your viewing window in the headset may be far from the center. For this situation there is a remote recenter key (volume down) to reposition the viewing window to the center of the photo but keep the same zoom level.

There is also a new free app consisting of a short collection of 3D photos from a vacation trip to Barcelona, Spain, where we visited a food market "El Mercat de La Boqueria". The photos were taken with a FujiFilm W3 camera (3D), aligned with Stereo Photo Maker and color adjustments made with Lightroom. This app demonstrates how the head movement works in the paid app.

Henri Cartier-Bresson Interview in NY Times

Photographer F. James Conley wrote a blog entitled "An Interview with Cartier Bresson on the X-Pro2"  http://fjamesconley.com/effeleven/2016/5/13/an-interview-with-cartier-bresson-on-the-x-pro2. His blog posting is a clever way to review a camera as if it were used by a famous photographer. It caught my attention because I'm a fan of Henri Cartier-Bresson's work. In the article there are also links to an interview with Cartier-Bresson by photographer Sheila Turner-Seed and transcribed by her daughter Rachel Seed and published in the NY Times.

I think the interview contains jewels of wisdom for photographers. But I would disagree with his assessment of color photography. The technology of digital color photography is so much better now than it was in his time. 

Here are links to the two articles with the interview transcription:


Animated Photo Merge Video

I created this video from two photos by blending them with program code I wrote using Processing 3.1.

Here are the two photos:

Ephemeral Art - 3D Fruit Sculpture

Fruit and Vegetable Sculpture 3D Photo

There is so much short lived, ephemeral art, that you must photograph it before it is gone. This includes subjects like the fruit sculpture above, as well as ice sculptures, beach sand sculptures, body painting, light painting, platted food designs, sky writing, sidewalk chalk drawings, and all types of performance art, to think of a few. When it's gone, the photograph becomes the Art, so you have to capture it well. And 3D photos will make it look virtually real (VR).

UPDATE - more ephemeral art:

Morikami Museum - Japanese Tattoo Exhibit

Japanese Tattoos, front panels

During a visit to the Morikami Museum and Gardens, Delray Beach, Florida, I was intrigued by the "Perseverance: Japanese Tattoo Tradition in a Modern World" exhibit by photographer,  Kip Fulbeck. Standing out in the exhibit are the larger than life panels with front and back photographs of the whole body Japanese tattoos, known as irezumi. Many more photographs of the intricate tattoo fine art were shown with both male and female subjects.

I shot the 3D side by side photos using the cha-cha method with my Samsung S6 phone camera and edited with Lightroom, Stereo Photo Maker, and Faststone.

Example 2D to 3D photo transition

What you see here when looking through a stereoscope is a 2D picture of a plant followed by the same plant in a 3D view. Your vision transitions from monocular to stereoscopic and back. The plant comes alive and pops in 3D compared to 2D.

I took three photos of this plant using the stereo cha-cha camera method: left, center, and right. After aligning the 3D photo formed by the left and right photos in Stereo Photo Maker and aligning the center photo with the 3D photo in Photoshop, I made this GIF image.



3D Stereo Photo Viewer - Cat

I have been busy improving my 3D Stereo Photo Viewer app for Android. One new feature I added works directly with my blog site. If you are viewing this page with an Android phone in the Chrome browser, then all of the photos embedded in this Web page can be seen using the viewer by clicking on the link here to launch the app:

And 2D photos can be viewed too.
