Amazon is today ( 15th ) offering the kindle version of "Digital Photography Basics: A Beginner's Guide to Getting Great Digital Photos" for free.
I have downloaded it but not had time to check it out yet, so I can not vouch for the quality or content.
But something for nothing is alway worth a look, so if you are interested go to your local Amazon and search for
Digital Photography Basics: A Beginner's Guide to Getting Great Digital Photos
It might still be available after the 15th, the free books sometimes are for a couple of days.
@jools you may be interested in this too.
