Firmware Upgrades are one way to revitalize old Hardware but we are still limited by the Hardware itself. So what best to do before donating the Device to XDA? How about a single dedicated usage like a DIY 3D Camera?

​

After careful consideration and plenty of “3D is not important for my decision” talk I decided on a Samsung 46” LCD 400Mhz 3D Capable TV. What a beauty and 3D came as a bonus with two glasses included. Unfortunately free content is rare so I thought and I set out to search for more material. As I soon found out Stereography has been around since the 1840’s. There is an abundance of Tools and Material you just have to find it.

​

I also realized there are a whole bunch of 3D Standards but found the Half-SBS (Side-by-Side) function to work best for me. This brought up an idea. I still had two HD2’s laying around and I figured from what I read Stereoscopy is really not that much more than taking two pictures side by side at the same time. Easy enough I used my 20 year old Stockis/Mechano set to construct a crude frame for the HD2’s.

​

It took a couple of tries to get the rig to be easy enough to carry with me and take pictures simultaneously. An Android or Windows Mobile App to synch the Cameras would be nice to have but for now it works fine manually. Up to this point I really didn’t expect too much from my contraption. Once I had the rig done I took some test pictures, hooked the Phones up to the Computer and transferred the files. With the “StereoPhoto Maker” for Windows I created the final Stereo Pictures and transferred them to the TV. Among other things I suggest you try Auto Alignment to optimize the 3D Image.

​

Eager to see the results I turned to my TV, put on my Glasses, and Voila a perfect 3D Image. I can now capture the world in 3 Dimensions and all this without going bankrupt in this dimension. Off course a little adjustment and practice in taking 3D Pictures will most likely be need to get the best results. Here are a few Tips and Tricks to get you started.

​

Intra-axial distance on 3D Cameras:

The intra-axial distance is the distance between the lenses of the Camera. Two HD2’s next to each other have a Intra-axial distance of 7cm. The average human intra-axial distance is 6.35cm. Furthermore the distance from the Camera to an Object should at least be 30x the intra-axial distance.

Optimal Average: > 1.90m

Optimal for HD2’s: > 2.10m

​

​

The Concept of Parallax on a modern 3D LCD TV:

The Distance an Object is felt from the Screen. Whereas the Screen has a zero or neutral Parallax.

Negative Parallax (comes out of the Screen)

Object shift -15pp to the left to get a negative Parallax effect.

Positive Parallax (goes into the Screen)

Object shift +12pp to the right to get a positive Parallax effect.

​

Objects are best felt as 3D when at the bottom of the image the objects come from the outside to the inside and at the top from the inside to the outside. Never the other way around or you will get a headache looking at the pictures in 3D.

HD2 / Phone Camera Tips:

The HD2 Camera is good enough to take these kind of pictures but you are preaty much limited to good light conditions. I prefer Portrait Pictures on my 46" TV. Turn off the Flashlight it will make a simultaneous pictures much easier to take.

3D Films with DIY 3D Camera

For 3D Films the timing is absolutly crucial. Use StereoMovie Maker to auto allign, rotate, and create the final 3D Movie. See Links in next Post. In order to keep it the picture sharp move the Camera slowly and stay atleast 2.10m away from the Object.
