Video camera - automatic exposure problem
The room lighting in the computer lab was not suitable for lecture capture. The lights were the latest specification that are designed for computer room. They send the light straight down and not sideways to reduce screen reflections. The result is that their is little light directed at the presenters face. This was made more pronounced by the fact that the background was white. The automatic exposure on the video camera cused the presenters face to be too dark to see any features. After experimenting by hanging variously coloured sheets behind the presenter it was decided to paint the background wall a mid blue colour. This has solved the problem.
