My dad gave me a copy of The Negative and The Print for Christmas. OK I already had them, but still not an unwelcome gift.

I just picked up on his advice to have Dektol and Selectol Soft stock on hand and mix them in various proportions to get intermediate grades... Now why didn't I do that 10 years ago when I first read it? Why don't I do that now, especially since I am committed to graded paper? Well maybe since I only have one bag of Selectol Soft. But so simple an idea. And how many times you can read a book cover to cover and not pick up a detail.

That's why I love these books, sure they are full of information. But you can go back later and get something you missed before.
