Brief: To grade and finish a new 6 x 60-minute BBC investigative drama.
How it was done: Kevin Horsewood graded HDcam rushes on Digital Vision Film Master before the online was completed on DS Nitris by Sion Penny and Simon Giblin.
Additional visual effects work included making light beams come from helmet-mounted torches and making a character appear as if in deep water instead of just below the surface.
Watch it: Tuesday 8 July at 9pm on BBC1 and BBC HD.
