How a camera works-Questions

I learnt that a camera has over 1 million different shades of
colours. 
I found it easy to answer the first couple of questions quickly.
I found it hard to find the answers out of the book because it was a very big book. 
I really enjoyed reading this book because it was really interesting to find out how a camera works.
Next time I need to work on finishing this quicker.
My Blog Post shows I am a Stepping Up because i still have lots to work on.
