Online 3D Photo Web Sites

The following web sites are more than just Flickr – they provide online 3D editing tools. You typically upload two images, a side by side 3D image or an MPO file – and then make alignment and other changes “in the cloud”. Once done, your finished 3D image can be stored in your online photo gallery and viewed in multiple formats, as selected by the viewer – such as side by side cross eyed views or anaglyph.

  • Dualfoto.com
  • 3dMedia.com (uses offline composition software, web site does not display photos on my NVidia GPU – because I do not have a stereo monitor)

Fujifilm 3D W3, Lumix 3D1, Toshiba Z100, Sony Bloggie 3D specifications

A comparison of inexpensive, consumer level 3D cameras in terms of the specifications that matter for 3D photography and video. There are other cameras besides these but these are affordable and available from many vendors. Another day I will look in to specifications of higher end cameras, such as the Sony TD10/TD20 3D video cameras.

Update: Since posting this item it appears that most of these cameras are in the process of being discontinued and you can find some great half price deals right now. It is likely that new 3D cameras will be introduced in a few weeks at the 2013 Consumer Electronics Show.

An interesting observation – some of these cameras have 1920×1080 image sensors but actually cut the image in half when encoded into video. The reality is they are not 1920×1080 but 960 x 1080 x 2.

In addition, the frame rate offers additional temporal resolution.

Let’s compare the image quality in terms of actual resolution, as well as resolution in time by calculating a “mega pixels per minute” rate:

  • Fujifilm W3: 1280 x 720 x 2 x 24 fps = 44.2 MP/minute
  • Lumix 3D1: 960 x 1080 x 2 x 30 fps = 62 MP / minute
  • Toshiba Z100: 960 x 1080 x 2 x 30 fps = 62 MP / minute
  • Sony Bloggie 3D: 960 x 1080 x 2 x 30 fps = 62 MP / minute
  • Generic 1280 x 720 x 30 fps = 55 MP / minute
  • Generic 1280 x 720 x 60 fps = 110 MP / minute

Interestingly, depending on many factors, your highest image quality might come from 720 x 60 fps because it delivers more potential information to your eyes over time.

Shooting 3D with my two Kodak Playsport Zx3 cameras, I think the 720/60p dual camera view looks on par with the 1080p/30p view. But that is also because after editing and 3D processing, the output of a 1080p video often ends up as a 960x1080p side by side video (as needed, for example, to upload to Youtube).

Figuring out which is best can get complicated!

Courts ruling that video recording police in public is legal

It is hard to believe, in this YouTube age, that taking video of people in public could be a crime. But the police are serious about not wanting to be recorded — and they have been making arrests to prove it.

via Adam Cohen: Is Videotaping Police a First Amendment Right? | TIME Ideas | TIME.com.

A U.S. Court of Appeals in Boston, a Court of Appeals in Chicago, and a filing by the U.S. Department of Justice are establishing that the people have a right to record police activity in public. Continue reading Courts ruling that video recording police in public is legal

Build your own 3D dual camera mounting rails

Ritwika Mitra shows how to build your own dual camera mount featuring an adjustable interaxial distance for 3d stereoscopic photography or video. Ritwika is a high school senior, by the way. Cool young woman! She and her sister are also the founders of the non-profit Rennow.org.

The details begin at about 2:30 into the video. I built this but I also use a fixed mounting bracket that is simpler and smaller. At some point, I will post photos of my set up for 3D.
