Phantom Slow Motion Camera Used to Study Coughing Reach!

Phantom Slow Motion Camera

Schlieren Imaging has always been a very narrow and specialized field of imaging. It can visualize air perturbations in a fluid-like way that can show the reach in this case of someone’s breath and heat dissipation to see if a mask makes a large enough difference in transmission of infected airborne particles compared to no covering.

By using a Phantom VEO4k 990 slow motion camera at 938fps and a speckled background with specialized angled lighting, researchers were able to test a variety of masks while coughing to see the effects.  You can watch the video posted here and also check out the full study available here if you want to dig deeper. → Continue Reading Full Post ←

Blackmagic URSA Mini Pro 12K is Frame Rate Beast!

Blackmagic URSA Mini Pro 12K

The Black Magic Design URSA camera line has been one of our favorite high frame rate options for many years now as it is a blend of excellent quality at a relatively low price with the added bonus of RAW recording and ProRes options.  Now the company has announced the latest iteration of the camera with a monstrous pixel size of 12k or 80 Megapixels per frame. All of this in an APS-C super 35mm crop from Full Frame sensor that is built to satisfy the requirements of their Black Magic RAW codec or BRAW for short which is in this camera the only recording format available.

What interests us as always are the high frame rates and this camera does not disappoint when it comes to this spec. The only real problem we see is that recording is made only from 4k resolution and up, completely avoiding 3k, 2k and HD resolutions which could yield even higher frame rates with probably a huge crop in the 80MP frame which will probably yield a noisy and artifact prone image hence why they probably avoided recording down on those modes. → Continue Reading Full Post ←
