Digital photography for dummies!

Finally I bought a photography book - the obvious choice was Digital Photography for Dummies. I figured it was high time I actually learned a few things about photography than just being a clicking maniac! I did take a quick class about photography basics a few months ago, but I need something more - like a quick guide with comparative examples - what happens when you take a picture at 1 fstop vs. another.
Another beauty I found was this book - Digital Macro Photography by Ross Hoddinott: This dude is apparently a leading nature photographer who is into macro and has won a lot of different competitions. I liked the book because it gives a lot of examples with particulars about how the picture was taken. The language is easy and the book has great tips to improve shots considerably. Now on to actually reading the book...
