I asked Dorothy to come in and give them a recording master class based on her years of extensive location experience. The time and money spent on this paid massive dividends on the ground, as the AP's were far more confident about getting the right sound and working with the self shooting PD's to achieve that, in the edit, where more material was useable, and in the dub, where less time had to be spent on the mix than in series 1. I would always now want Dorothy in for a day to supplement any basic technical training
