Thinking about the next project/module

We have to present/bring in 7 to 10 images at the next meeting to show our current work.  I have been working on composite images over the past few months and I am looking at producing something about this.  I am not sure what this will entail at the moment but an idea has been itching at the back of my head for sometime about 'contact sheets'.  Why was a particular image chosen and what lead up to that image.  As you can see this is not a very well formed idea at the moment but it is something I thinking about.  Not sure how this will play out?
