Blending Mode

Blending Mode

Blending modes apply a specifi c mathematical formula to
the operation of compositing a layer with those behind it.
These are essential because they mimic real-world optics

When compositing an element that is made up more of
light or shadows than refl ective surfaces, for example
footage of fi re shot on black, it is essential to use blending
modes instead of a luminance matte—don’t try keying out
the black (see Chapter 14 for more details). You can of
course use selections combined with blending modes to
get the best of both worlds.
The primary useful blending modes are detailed later in
this chapter
