exposure book

I saw a link in here about a must have book for beginners, something to do with exposure, can someone either put up the link or tell me what the book is thanks

Is this the book your looking for here
if so i can highly reccomend it for a begginer ..it explains all the relationships between speed, aperture and iso and goes on to explain how to get good,correct exposure on photos..a must have book for the begginer and also worthwhile rereading for the more experianced to relearn old techniques!

Thats the one I was looking for, thanks

Highly recommended, well worth the money.

I agree, one of the best book ever written about exposure.

I have 4 of his books. They are all very informative, but slightly overlapping.

I highly recommend them for anyone trying to learn about photography. They speak in plain language and give you exercises to practice.
