Lasers Target Classical Guitar For Rolling Shutter Effect (String Oscillation) - Is It Safe?

It takes a lot of light for the rolling shutter effect to work and provide the illusion of string oscillation we're after. Lasers do provide a lot of light and it's very focused, for a high-contrast effect. The camera here is a Canon 5D Mark III. Settings during guitar playing are 1920x1080, 24 fps, 1/1000 shutter speed, f/2.8, ISO 4000. Laser power needs to be measured to make sure we're using the lasers safely. The high accuracy laser power meter used in this video for safety assessment is a PRONTO-Si from Gentec-EO Inc. https://www.gentec-eo.com/products/ph... We measured a total of 31 mW of power from the green laser (532 nm wavelength, 2 mm beam diameter) and a total of 45 mW of power from the 360-degree red laser (635 nm, 2π.200 mm x 2 mm beam surface area). Since only a 7 mm x 2 mm red laser beam would reach my pupils (7 mm is the average diameter of a fully dilated pupil), it yields a diluted power in this area of 0.25 mW, which is rather safe. On the other hand, working with a focused, Class 3B green laser requires protection. We measured that my sunglasses attenuate by a factor of 10 at 635 nm and 7 at 532 nm, making it all safe because less than 5 mW of remaining power could then reach my eyes. Always use safety eyewear adapted to your lasers. Go to my blog post about Laser Safety Officers to learn about laser safety standards and the type of detectors required to measure laser power, energy and beam profile. Contact me if you need a power meter! https://blog.gentec-eo.com/blog/when-... Many thanks to Josée Lecompte for lending me this camera with two lenses. Contact her for your corporate photo needs! http://joseelecompte.com The two guitar tracks were recorded in one take using the Shure SM57 and Sennheiser MD421-II microphones simultaneously, plugged in a Focusrite Scarlett 2i2 preamp interface. No editing was done, no EQ was applied, just compression and reverb. The guitar is a Ryoji Matsuoka Model M50 made in Japan in the 80's that I found at a flea market in Tokyo. A pretty nice encounter. I wrote this piece of music except for the heavier part which is the bridge section of the song Creeping Death by Metallica.
