hard way: try to tell your mind to focus in the fact that all the image is a whole thing (concentrate in that), with practice your brain will form the whole image at the same time without processing the individual objects that will trick you.

half-hard way: view the image askance, try to lightly turn your head outside the picture and concentrate in the whole picture. This way must be easier because the brain process different the information that comes from the lateral part of the eye -faster, without much detail, with poor quality color and looking for movement-.

easier way: focus in one object and move your head from side to side (lightly, remember that the speed of the movement depend of each person); As the brain can’t process all the details, it will not have other option to store the whole picture and save it while you are moving your head, and -Whola!- now the image are static.
