Nagasaki in 3D
01/21/2007
And for the first time, here is a post that is not directly related to Japan. Stereoscopy is a technique used to recreate a 3D effect from plain, 2D pictures. Although the effect is striking, the principle that lies behind is extrememy simple: it's based upon the fact that our eyes see different images, which are computed by our brain to create a 3d representation. Similarly, stereoscopy consists in taking two pictures instead of one, one for the right eye and one for the left eye. Then it's all about how to make each eye focus on its image...I'm not going into further details about the techniques, I'll leave it to you to refer to dedicated websites to learn about that. A good start would be to check out the wikipedia article, and then browse the web for stereoscopy-related websites.
So what's the relation with my blog? Well during my last trips, I took a couple stereo pictures...They're not of the best quality because I made them manually. Ideally one should use a tripod for better picture synchronization or even better, a dedicated double-lens camera (which are not really produced anymore, unfortunately). However some of them are really nice! The landscape pictures are not very good, I still need to increase the interaxial distance (hyper-stereoscopy), but I'll improve!
Now it's up to you, give it a try! With a little practice, it actually becomes easy to see 3D almost instantly and without any gimmick. For each couple of pictures, you will find the "cross-eye" version and the "parallel" version. Everyone has their own preference, although parallel viewing is generally much harder to achieve (but provides a better result).
Here are the pictures:
- Nagasaki 1 : cross-eye - parallel
- Nagasaki 2 : cross-eye - parallel
- Nagasaki 3 : cross-eye - parallel
- Nagasaki 4 : cross-eye - parallel
- Nagasaki 5 : cross-eye - parallel
- Nagasaki 6 : cross-eye - parallel
- Nagasaki 7 : cross-eye - parallel
- Nagasaki 8 : cross-eye - parallel
I significantly reduced the image size but I can send the originals for a better effect, just ask me.
Now it's up to you! If you really try hard but still cannot manage to see the pictures, contact me and I'll try to give you some pointers.
I'll upload more stereo pictures every now and then...
