I covered this, the 3rd of the EuropaBio conference at the 5 star Sheraton Grand & Spa in Edinburgh with a drinks reception at Edinburgh Castle.
350 delegates pretty well filled the main room. Lighting on the stage was a challenge to say the least (none) but was able to direct the flash directly to a near white ceiling which resulted in light coming from above the speakers and with the bounce card out it worked out OK.
See here for some short interviews filmed on the first day and here for some interesting stuff on the way tyres may be made in the future.
