I wish there were such a book. So, I'm not sure I understand the relationship between the mode dial (iA, P, A, S etc) and the menu screen (push "menu/set) on the LCD display. For example, if I'm in iA, the menu selections are reduced in number, which makes sense. But if I'm in any of the others, there're many more menu item choices. If I'm in "A" for example, do the choices I make in the LCD menu screen apply to P, S and M? The reason I asked is somehow, I switched resolution on some of the pictures I was shooting and some others were in b&w all accidentally. I figure I must have been fooling around in onemodeanddidn't realize it would carry over to another (viewfindercorrextly showed b&w BTW but I was in a hurry.
