It's a combination
of tricking the eye (The blurring distorts you're mind's perception of depth/distance/size) and altering the colours to more accurately represent those commonly found in model paints.
The name comes from the orignal (manual) method using a camera lens that tilts and shifts, giving a very similar effect to that above. It's only fairly recently become common to replicate this using Photoshop etc.
