If possible take the pages out of the binder and lay them side by side you might find it easier keeping photofocus by flipping the pages rather than wrestling with the binder.
Also photoread the binder material upside down... whenever you find yourself drifting out of photofocus with page turning difficulties it seems to help to have the book upside down... probably because it reminds the mind to stay in photofocus state since most people cannot read upside down consciously.
