Experiment of a slide-show with constant Far disparity and limited Near disparity.
Constant Far: +3.8% respect the image width.
Limited Near: -0.8% respect the image width.
All images are 1920x1080.

Synchronism measures on Samsung NX1000
Album created by afgalaz
The shots here are made to the screen of an analog oscilloscope, which is triggered with the remote release shutter of the two cameras.
These tests provided several interesting findings:
1- An analog oscilloscope with delayed sweep is possibly the best tool for synch measurements
2- If one camera is inverted respect the other the synch error is different for different areas of the image.
Rendered for viewing on 5.5" auto-stereo phones. WARNING: SICKNESS ON SCREENS WIDER THAN 700MM (32" DIAGONAL)

My take on synchronism discussion

My take on old stereo cards
Album created by afgalaz
This is my take in the discussion on photo-3d about refurbishing old stereo cards.
The examples are downloaded from https://www.loc.gov/photos/?q=keystone+view+company (Congress Library).
They are aligned and rendered generating two separate left & right aligned images using STMANI3.
Then mixed the aligned images with the unaligned raw scan of the card using GIMP (this step was the most time consuming)
