The Bloomsbury Media Cloud was officially launched on 20 May at an event held at the London Knowledge Lab and I was invited to cover the event. Like most events which involve presentations, coverage of this event had its challenges, mainly from the contrast between a very bright projection screen and the presenters standing by the lectern in the darkened room/auditorium. In a normal situation you would use flash to compensate for the lack of light on the subjects. However, it was a smallish space and lack of lighting except for the presentation screen meant that any flash would be very noticeable and I didn’t want to disturb the event and presentations with its use (the same applies for photos taken during the service at weddings) so I had to be a little more creative with my photography.
One simple trick is to wait for the moment when the presenter crosses in front of the screen and is lit by the projection itself. This also often produces some rather interesting images depending on the presentation. Another method is to compensate for the high dynamic range by taking several exposures. One at the level of the presentation on the screen the other at the level of presenter and carefully merge these together later in photo editing software, such as photoshop. Of course there are other methods as well :-)
