I'm sure this has been answered somewhere on these boards but I couldnt find the answer, and it's probably in the book, which I am going to give a more thorough read tomorrow morning..
When PRing single pages, like computer printouts or web pages, where is it best to keep focus, since there is no blip page... Just look, in photofocus, at the center of the page, or look at the white colum on the left side of the paper where the spine of the book/blip page would be?...?
