Today I have just been applying the finishing tweaks to my final video. I revisited my last scene, which shows my actor tossing a grenade through the bunkers window. I duplicated one of my debris layers and scaled it down a bit, to give the impression of smaller chunks of rock and dirt blowing out the window after the explosion. I then added and tweak an adjustment layer over the existing debri layer to colour correct the chunks to a darker muddier colour.
