Hidden Kingdoms 2

I'm looking forward to viewing more groundbreaking cinematography from the BBC's Natural History Unit in this evening's episode of Hidden Kingdoms: Secret Forests on BBC One at 8pm (CLICK). The use of blue screen backgrounds allows the creation of dramatic composite images, such as this Eastern Chipmunk under attack by a Great Horned Owl (2014). But blue screen isn't the only trick up the sleeves of these film-makers. The techniques they use have got to be seen to be believed. A TV must.
