I finally finished writing this section of the blog! Please check it out – thank you! Which 3D cameras to use? | 3d.coldstreams.com.
“Testing the Effectiveness of 3D Film for Laboratory-Based Studies of Emotion”
Full text of study published in: PLOS ONE: Testing the Effectiveness of 3D Film for Laboratory-Based Studies of Emotion.
The authors found little difference in emotional response of watching film clips (not entire films) in 2D versus 3D.
The study had 408 volunteers view selected clips from 4 films in 2D or 3D while hooked up to cardiac monitoring machines. Physiological data was used as a proxy for the viewer’s emotional state.
The British press has concluded this proves that 3D is worthless and announced that all British reporters plan to cover one eye with an eye patch, in their future lives.

Brian May’s collection of 3D stereoscopic photography to go on display at Tate Modern
The Victorian craze for 3D stereoscopic photography is to be the subject of a major gallery exhibition for the first time – thanks to former Queen guitarist Brian May.
Perhaps lesser known, Dr. May is also an astrophysicist. He’s been collecting historical 3D stereoscopic photos for decades.
Olympus E-M1 firmware update will add “keystoning” feature
“Keystoning” refers to the distortion that occurs when the camera sensor is not in the same plane alignment with the subject and is very noticeable when, say, pointing your camera upwards at a building or big ship.
According to this rumor, a firmware update to the Olympus E-M1 will provide a software feature in camera to correct for this distortion: (FT4) E-M1 firmware update will add “keystoning” feature. | 43 Rumors.
Keystoning also occurs when shooting 3D and using toe in on the left and right cameras to position the primary subject at the viewing plane. Some 3D photographers choose to shoot 3D using cameras that are strictly parallel in their forward view, while others toe in the camera slightly (I believe director James Cameron does this in his films). The non-parallel view is helpful for alignment but can create keystone effects in the image. These keystone effects can be corrected during editing (e.g. Sony Vegas and Movie Studio include features for this) by warping the original (but keystone distorted) image back to normal.
Which leads to a question: would this firmware upgrade enable toe-in of a paired E-M1 cameras with in-camera keystone conversion for 3D application?
Who knows!
