Case study: compositing
Editor Nial Brown is an effects specialist. He talks us through the process of inserting shots of a train into a scene in EastEnders.
The compositing technique in post-production can give you the best of both worlds, because two elements from entirely different shots can be combined into the same shot.
Here, Nial takes us through the process of getting a 'Walford East' train into EastEnders, which is filmed in a location away from any train lines.
"Sweeping the exposure can give you back the detail of the shot." – Nial Brown
This involved using various exposures on one shot in order to retain all of the detail, such as railings and branches, that he wanted to keep.
Then he was able to insert the train and add reflections in nearby windows.
