Correction to the 2016 Technology Year in Review

  Correction: In the video of the Technology Year in Review, a modified version of what was presented at the HPA Tech Retreat, the Polaroid Snap camera shown starting about 8:12 in does make instant prints but is not a film-based camera. There are also new Polaroid instant-film cameras being sold, such as the PIC-300, […]  More

Regarding the recent HDR presentation

There is both a correction and an elucidation for “HDR: The Great, the Okay, and the Yikes!” Correction:  About 35:30 in, the term “ground glass” is used for what test viewers looked at during projector-illuminated tests.  Actually, it was an LCD screen being rear-illuminated by the projector. Elucidation:  At about 26:24 in, the chart says […]  More

"Bang" Presentation: A Bit More

I neglected to describe all of the images on slide 19. The upper right image on that slide (at right here) shows that, in a cinema auditorium, detail resolutions beyond HD might be visible to everyone in the audience, even in the last row. The ARRI Alexa camera, from the same company that provided that image, […]  More

Handwriting Matters!

In many of my Fandom of the Opera lectures and some of my other writings about media technology and opera, I’ve made reference to two people who are candidates to be called the first person to use electronic home entertainment. I cannot yet tell which had priority. The year was 1880. The month was likely November. […]  More

The Earlier Earliest Bell Recording

This week, there has been a lot of publicity about the first recording of Alexander Graham Bell’s voice, an 1885 disk, finally being heard thanks to the latest technology. But there was an earlier recording, and it was heard in 1937. The headline of the story in the October 28 issue of The New York Times that […]  More

Seeing Sound Waves

John Huntington posted a comment on my “Late–and See?” post about latency and lip sync.  It includes this link to a video that illustrates very well the speed of sound:  More

Not Quite the "Cure" for Stereoblindness

I’ve posted a comment to the story that implies that the movie Hugo cured someone’s stereoblindness.  But the person was never stereoblind.  Here’s more from Professor Banks: “The data show quite clearly that Bridgeman had stereo but that his thresholds were not normal (that is, his stereo vision was reduced, but certainly not absent).  “We have […]  More

Comments on the Tessive Time Filter

In a previous post, I described the Tessive Time Filter, subject of a presentation and demonstration at February’s HPA Tech Retreat.  John Watkinson submitted a comment on it, and Tony Davis, Tessive’s founder, responded.  First, here is John’s comment: The Tessive LCD shutter Numerous claims have been made for this device which I consider here.

Commercial vs. Non-Commercial Satellites

In my post “Satellites Are Really Old,” I distinguish between the Emmy-winning first commercial geostationary satellite, Early Bird, and the earlier non-commercial Syncom III. Was the “commercial” distinction Emmy-worthy? Here’s a link to a story about how the 1964 Tokyo Olympic Games coverage was delayed in the United States precisely because it was carried on a […]  More

The First Holographic Video

The originally posted version of “The Best 3D Conference” indicated an apparent conflict between Mark Lucente’s and Michael Bove’s statements about the beginnings of holographic video. Lucente has pointed out that he was referring to work on actual displays, whereas Bove’s earlier date referred to the theoretical. Lucente’s comments have been appended to the bottom […]  More
