The magic of slow motion recording

It was a long time ago when I first saw, and was fascinated, by the image of a bullet going through an apple.How could one possible capture “the moment”? At that time, indeed, it was magic.

Today’s technology makes it easier (not easy!) to capture these kind of moments. It can also help in creating slow motion video in 3D with tools and software that are affordable to most of us.

I found an amazing slow motion video, watch it below -it is really worth your time-, that demonstrates the tremendous advances of technology.

We have got familiar with slow motion using our smartphone (for tips look here): the smartphone captures many photos per second (up to 240 in my iphone 12) and when you play it at a lower time frame, like 30 fps you extend the time by a factor of 8 (what took 1 second now it is taking 8 seconds). Using software you can stretch the time even further .

Here is the two key tech that are giving us a peek into time: a fast shutter able to take many photos (frames) per second and software to process the images. This latter can take two images in a sequence and create -often using AI- intermediate photos. Also the software can merge images taken from different point of view to create a 3D image in slow motion. What is really amazing is that all of this is available to each of us (wee can learn how to do it and it is affordable).


About Roberto Saracco

Roberto Saracco fell in love with technology and its implications long time ago. His background is in math and computer science. Until April 2017 he led the EIT Digital Italian Node and then was head of the Industrial Doctoral School of EIT Digital up to September 2018. Previously, up to December 2011 he was the Director of the Telecom Italia Future Centre in Venice, looking at the interplay of technology evolution, economics and society. At the turn of the century he led a World Bank-Infodev project to stimulate entrepreneurship in Latin America. He is a senior member of IEEE where he leads the Industry Advisory Board within the Future Directions Committee and co-chairs the Digital Reality Initiative. He teaches a Master course on Technology Forecasting and Market impact at the University of Trento. He has published over 100 papers in journals and magazines and 14 books.
