How Active D-lighting works

Hi,

I could not find an exhaustive article about how active D-lighting works. For what I understand this is what the happens when D-lighting is on and shooting only RAW:

1. The meter evaluates the scene and if it finds there a need to apply D-lighting then:

2. It underexposes the picture

3. Picture is taken

4. RAW file is processed while in the buffer and shadows are opened up

5. RAW file is written back to the card.

Please suggest your flow if the above is wrong. Please point me to any in-depth paper on the topic you might be aware of.

Thanks.
