Query: Out of Date Book

This was once a very good introduction to exposure for beginners. Alas the years go by and the book is seriously out of date. The concepts are still correct and somewhat useful. However, the book was written before the advent of serious digital cameras and before Photoshop and other programs were available to improve images. I think that if one looks at the dates of all the glowing reviews, you would see that they were written some time ago. I would look for a more up to date discussion of exposure.
