What is Stereopix?

Stereopix is a social network for stereophotographers where they can publicly share their stereophotographs and discuss them. The photographs are dynamically transformed into various formats suitable for different kinds of viewing methods or display technologies.

It is run by JackDesBwa and is not backed by any company. Authors keep their rights on the photographs and are responsible for all the content they publish on the platform. The medium-term aim is to have a platform self-sustained by the donations of its visitors and publishers.

What is a stereophotograph?

A stereoscopic photograph (or stereophotograph, or stereophoto...) is an image composed of two slightly different views specially crafted to create the illusion of relief when exposed to each corresponding eye. They are also called 3D photographs because you can truly sense the depth. This is really amazing!

The trick is based on stereopsis, a visual and neuronal mechanism that creates depth from two separated points of view, such as the ones seen by our eyes. The characteristic tiny differences between the views (real or photographed) allow us to rebuild a complete 3D representation of the world. Our brain is fantastic.

A variety of devices use different principles to guide each view to the appropriate eye, and of course, the stereophotograph has to be presented in the format adapted to the one used. Some trained people are even able to view side-by-side representation without any device (ocular gymnastics required). This website converts the shared photographs in different formats so that each visitor can choose their preferred way of viewing the images.

If you did not know about stereoscopic photographs before, a lot of amateur's and clubs' websites explain different techniques to view (and take) them. Learn and come back to enjoy photographs shared on this platform, and perhaps publish your own ones.

How to get best Stereopix experience?

You can have access to the content with any browser, however some provide better experience.

Basically, these are the 3 main (easily fulfilled) recommendations:

  • Graphical browser
  • Webp image support
  • Javascript enabled

The first one is quite obvious: as the main content is made of images, a graphical browser (as opposed to text-only ones) which can display them directly is more suitable for enjoyable exploration.

The image format is primary webp, which offers good compression with low quality loss, and is now supported by most up-to-date browsers (see compatibility chart). A jpeg fallback is provided in case of absence of support (the logo in the header indicates fallback mode), but the quality and definition of the images are slightly reduced and this part is less tested.

The stereophotograph viewer uses javascript to transform source images into various viewing formats. Thus, you need to allow script execution to get the best of Stereopix. In case of disablement, a fallback side-by-side image is displayed and some features are disabled.

Please use modern browser to get the best of Stereopix.

How to use the viewer?

By default, the viewer displays the current image. By clicking/taping on it, you can display other options:

  • Various buttons allow to choose the 3D display mode. Their significations are listed in the next section.
  • You can also switch the viewer into fullscreen mode by hitting the fullscreen button (or use letter F)
  • You can swap left and right images on the fly with a dedicated button (or use letter W or X)
  • You can download the photograph with the download button. Warning: remember that most of the photographs shared here are not free to use. You can download them for personal usage only… do not steal them.

What are display formats?

The viewer is able to display various formats listed hereafter.

Note: You can keep the pointer over the icon to get the full name, and an abbreviation is visible too.

Left view SL
It displays only the left image (2D).
Right view SR
It displays only the right image (2D).
Columns Interleaved CI
It interleaves left and right images by columns.
This format is used by some 3D phones.
In advanced parameters, you can choose which image is displayed on odd columns.
Rows Interleaved RI
It interleaves left and right images by rows.
This format is used by some 3D passive monitors.
In advanced parameters, you can choose which image is displayed on odd rows.
Parallel view P
It displays left and right images (parallel) side by side.
This format can be viewed with parallel free-vision fusion (wall-eyed) technique.
In advanced parameters, you can choose if the images are separated in the middle of their space (as for VR viewer) or close to the other part (useful in freeview).
In advanced parameters, you can choose if the images are compressed horizontally (useful for 3D TV).
This format is used by most 3D TVs.
Cross view X
It displays right and left images (crossed) side by side.
This format can be viewed with crossed free-vision fusion technique.
In advanced parameters, you can choose if the images are separated in the middle of their space or close to the other part (useful in freeview).
In advanced parameters, you can choose if the images are compressed horizontally.
Anaglyph Monochrome AM
It displays the left and right images converted to monochrome and fused in anaglyph.
This format can be seen with cyan/red anaglyph glasses.
Anaglyph Half-Colors AHC
It displays the left and right images fused in anaglyph using the half-colors method.
This format can be seen with cyan/red anaglyph glasses.
Anaglyph Dubois AD
It displays the left and right images fused in anaglyph using the Dubois method.
This format can be seen with cyan/red anaglyph glasses.

What are categories?

To explore the hosted images, Stereopix provides special albums named categories.

Highlights category is automatically filled with stereophotographs recently highlighted by the community.

Fresh category is automatically filled with newly published stereophotographs.

Random category is automatically filled with random stereophotographs and the list is renewed randomly.

For connected users, Followed category regroups the photos of the stereographers you follow and Favorites lists the images marked as favorite.

Other categories are filled by the community, either by the authors of the photographs or other members who took time to classify them manually.

The categories are:
