28 days later utilised more often than not a crapload of post production with colour correction after a very clean shot had been created. All of it was done on Canon XL1' with 35mm adapters then lighting added in post so the overall effect could be controlled. With controlled windows of time this is the only way Boyle secured shutting down london where he needed, along with the obvious motorway closures.

I have to say, most post I have done like this is great fun and a proper challenge when creating mattes. Much better than all the bluescreen/greenscreen stuff I have done recently, which is plain boring.
