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.
Positive

I was so excited when I received this air bed, but after sleeping on it on the first night, things changed. Every single night I had to put more air in it in order to keep it firm. There were no leaks that I could hear, but it was a pain to keep putting air in it every night. If this does not bother you, the bed itself is extrmeley comfortable.Intex Pillow Rest Queen Airbed with Built-in Electric Pump
