Need help: writing a 5 pages photography book Chapter

Updated with Diagrams

I just woke up and noticed that you've updated the contest and mentioned that we need to add Diagrams as well. So, here is my updated entry, explained with diagrams. Rest, I've sent you designs in INBOX as well. If you select me, I can do further updates with the content and can provide more designs as well for free. Please check and give me detailed feedback. Thank You!
