Have you heard of an awesome website called Dear Photograph? I think it is a great idea and enjoy seeing all the pictures put up. So, I of course had to get the book version when it came out. The guy even read through it! I am constantly trying to think of my own 'Dear Photograph', but I haven't come up with one yet. I just think it is a fun idea and ties in well with taking creative pictures. Then, you say something about the photo. It also makes a nice keepsake.
Be sure and check both the website and the book out. You will not regret it!
