[EX Q]: While old and out of print, this book is a very good way to learn the basics of photography. You have to ignore most of the references to digital cameras as the technology has changed a lot.
[EX A]: Positive

[EX Q]: I bought this for my great nephew - 18 months old who is already learning to count and learn his colors. I also got him a dino puzzle by Melissa & Doug. Both items are really great. They are very durable and colorful so he likes playing with them and putting the shapes back in their places. The number puzzle is fun because when you take the number out, there are pictures under each number for example - take out the three - there are three turtles (I may have the wrong animal but you get the gist!!). His 3 year old cousin that visits often also loves playing with them so they have a good age range.
[EX A]: Positive

[EX Q]: Book has some interesting insight but does little to develop technical understanding. Is cheaper at B&N locally
[EX A]:
Negative
