Mmmmm - Some illumination on the speaker would be advantageous. Perhaps it would have been better filming/videoing from the right, rather than the left, side. Viewing it on my PC (running Centos of course), Mr Singh's talking is not always distinct. Different types of mic provide different levels of clarity. A laval mic (clip-on miniature microphone) with better audio would probably help. Am interested to know what camera and mic were used. When is the next presentation in the London/greater London area ? -- Regards, Paul. England, EU. England's place is in the European Union. Exclusively Centos for more than 10 years.
